Dyson Supersonic Nural: two-minute review

The Dyson Supersonic Nural hair dryer is the most hi-tech hair dryer I've ever used. The headline feature here is the 'Scalp Protect mode', which senses how far away your head is, then heats up or cools down to maintain what feels like a constant temperature on your scalp. All that means less heat damage; even if you put it right up to your head, it won't burn.

The Nural can also sense when you put it down, and drop into low-power mode in response, and when not using Scalp Protect mode, it also remembers your airspeed and temperature preference for each specific attachment. On test, I found these techy features all worked as they were meant to. While I guess they're not strictly essential to the hair drying experience, they're not just a gimmick either – each helps streamline and speed up the styling process. 

Alongside these new innovations, the Nural also has all the things that made the original Supersonic – widely considered the best hair dryer on the market (read about it in our Dyson Supersonic review) – so popular. Namely, very fast and efficient airflow, a design that's comfortable and easy to wield, and a range of well-designed, magnetic attachments that clip easily on and off. These attachments cater to a range of different hair types (short, long, straight, coily and curly) and include a unique Flyaway tool, which tames stray hairs with alarming effectiveness. 

While the attachments are broadly the same as with the original Supersonic, I would like to give a special shout-out to the redesigned diffuser, which can now be used without the prongs in so-called Dome mode, designed to define your curls. I have natural slight curls, and it's the only diffuser I've ever been able to use that hasn't transformed my hair into a frizz-ball of epic proportions. 

Of course, it's far from cheap. In fact, so far that 'cheap' isn't even a dot in the distance. The Nural's list price of $499.99 / £399.99 / AU$750 puts it firmly beyond the reach of many, and will perhaps make you question the necessity of owning a hair dryer that glows like a UFO and knows how close it is to your head at any time. But if you want the best of the best and have the budget for it, I have basically no complaints about how well the Nural works. 

That's the short version; read on for my full Dyson Supersonic Nural review. Alternatively, for more on this brand's haircare range, head to our Dyson AirWrap review,  Dyson Airstrait review or Dyson Coralle review.

Dyson Supersonic Nural review: price & availability

• List price: $499.99 / £399.99 / AU$750 
• Available: globally
• Launch date: spring 2024

The Supersonic Nural was announced in March 2024, and became available across the US, UK and Australia shortly after. 

Regardless of territory, it's expensive. At TechRadar, we consider any hair dryer over $200/£200 to be a premium product, and at list price, the Nural is twice that. In the US it's $499.99, in the UK it's £399.99, and in Australia it's AU$750.

It's the priciest hair dryer I've tested, but then it's also the most high-tech – by some margin. You're not paying just for the Dyson name, you're paying for the innovation and the engineering. (Okay, and a little bit for the Dyson name.) While I'm not especially mad at how expensive the Nural is, I do think it would be useful to be able to pick a cheaper option with fewer attachments. With their individual sensors and magnetic design, these are presumably driving up the price, and most people will only need two or three. 

For comparison, at time of writing the original Dyson Supersonic is $429.99 / £279.99 / AU$649. So the price jump between the two models is biggest if you're in the UK.

The most expensive GHD model is the GHD Helios, which is significantly cheaper, with a list price of $279.00 / £159 / AU$280. But it's nowhere near as intelligent as the Nural; you're definitely not getting like-for-like.

Dyson Supersonic Nural review: design

• Scalp Protect mode adjusts temperature based on distance from head
• Wide range of magnetic attachments for different hair types
• Light and easy to wield, although handle could be a bit longer

At time of launch, there are two different colorway options: Vinca Blue/Topaz (which I would call purple and orange) and Ceramic Patina/Topaz (turquoise and orange – the version I tested for this review). Otherwise it looks very similar to the original Supersonic – a streamlined version of a hair dryer, with a relatively small and lightweight barrel at the top, with most of the weight in the handle.

While Dyson seems to be getting into the habit of adding tiny, largely unnecessary screens to its new releases (looking at you, Airstrait), the Nural has escaped the curse. Instead, it's operated via buttons – a sliding on-off switch and cool shot button on the handle, and temperature, airspeed and Scalp Protect mode buttons on the barrel. All are small and unobtrusive.

At the bottom of the handle is a filter cage. To clean, Dyson recommends snapping the cage off (it's magnetic), soaking it for 30 minutes in soapy water, rinsing and drying. The filter can be wiped with a dry cloth to get rid of anything that may have built up there.

At time of writing, the Vinca Blue colorway comes with a cushioned 'presentation case', but there isn't one with the turquoise – sorry, Ceramic Patina – option that I tested. I felt both slightly short-changed, and a bit sad, that I couldn't put my Nural to bed like a little prince, but it's not a major issue.

Settings

You have three temperature settings (high, medium, low), plus a cool shot. There are also three airflow speeds – high (for when you're in a rush, or if you're a generally impatient person), medium (for regular use, if you're not an impatient person) and low (for diffusing).

Air speed and temperature are adjusted by pressing little buttons on the main barrel of the hair dryer, with three tiny LEDs to indicate which setting you're using. The Nural also has sensors that recognize which attachment is connected. When you snap on each one, it'll automatically swap to your last-used temperature and speed settings, to save you having to manually adjust as you go through your routine.

As well as the manual settings, there's the all-new Scalp Protect mode, activated via a button on the barrel with a hair follicle on it. When activated, the Nural uses a Time of Flight sensor to measure how close to your head the hair dryer is, and adjust so it maintains a consistent temperature. So when you have the Nural right up to your scalp, it'll lower the temperature, and if it's further away, it'll increase it. The idea is to minimize heat damage to the hair, was well as helping you avoid burning your scalp if you want to have the dryer right next to your head for precision styling.

To hammer home how space-age this feature is, the whole inside of the main barrel will illuminate to indicate the temperature – bright red for the hottest setting, down to blue for the cool shot. Is it strictly necessary? No. Is it cool? Yes. Is it hard to photograph effectively? Absolutely.

Finally, there's a Pause Detect function, which uses a motion sensor to identify when you've put the dryer down, and automatically cut the heat and minimize the airflow in response. There's intentionally a slight delay so the Nural doesn't cut out every time you pause slightly mid-style. This function is automatically on, unless you have a diffuser attachment connected.

Attachments

All versions of the Dyson Supersonic Nural come with the full selection of styling attachments. These are magnetic, and snap on and off the barrel of the dryer. They're broadly the same (save for some slight design tweaks) as those included with the original Supersonic, with the exception of the Diffuser, which has been redesigned more thoroughly.

Wave+Curl diffuser

This is the large diffuser, for waves and curls. It has been redesigned for the Nural, and can now be used in two ways. The central part, with the prongs, can be removed (it's magnetic) to leave a bowl-shaped attachment that Dyson calls 'Dome mode'. 

'Diffuse mode' (with prongs), is designed to add volume at the root, whereas Dome mode is designed to help define your curls. Dyson recommends you use the diffuser attachments with medium heat and medium airflow. It's the only attachment not to be compatible with Pause Detect. 

Gentle air attachment

This has crimped edges, and is designed to very slightly diffuse the airflow, for gentler drying compared to using it without. This one is a little confusing – a Dyson community page states it's 'engineered to be kinder to fine hair and sensitive scalps' but creating a 'gentle, cooler airflow', but then suggests it's used with high heat and high air flow. It is compatible with scalp protect mode.

Styling concentrator

Like your standard concentrator, this channels the air into a wide, thin blade, for smooth styles. It's designed for use with high heat and medium airflow, but can also be used with Scalp Protect mode.

Wide-tooth comb

A broader concentrator, with a comb extension, this attachment detangles your hair as it dries it. Dyson says it's for shaping and lengthening curly or coily hair, and it's designed to be used with high heat and high airflow. 

Flyaway attachment

This is for use on dry, straight hair. It uses 'Coanda airflow' – the same hair-bending phenomenon that powers the Airwrap – to flatten down flyaways. It's designed to be used with low heat and high airflow.

• Design score: 4.5 out of 5

Dyson Supersonic Nural review: performance

• Fast and effective drying; well-designed attachments
• Scalp Protect mode works well and doesn't impact drying time too much
• Auto-pause is useful

If Dyson really knows how to do one thing well, it's move air about. That's a more impressive specialism than it sounds – it's what earned Dyson reputation as the brand behind the best vacuum cleaners and the best fans around. And I wasn't surprised to find that the hair drying part of the Supersonic Nural is extremely effective. For rough drying, it gets the job done, and fast.

Because of the more compact shape and the fact that most of the weight is in the handle, it's more comfortable to hold, and easier to wield, than a traditional dryer. My only real complaint with the design is that the handle is a touch short for me – I'm either in danger of accidentally activating the cool shot button or getting my own 'cool shot' to the hand courtesy of the fan grille at the base of the handle.

As someone who has a habit of defaulting to the maximum settings on any haircare gadgets, I wasn't sure if Scalp Protect mode would be one of those features I'd end up neglecting, having prioritized extra sleep time over my long-term hair health. However, that hasn't been the case so far. 

I found that there was no appreciable difference in how long it took to rough-dry my hair in this mode compared to my usual blast-it-with-heat approach. This might be partly to do with the fact that the airspeed is so effective that it means you're not relying so much on cranking up the heat to get your hair dry. Scalp Protect mode has become my go-to for whenever I just want to quickly dry my hair. 

When comes to styling, the magnetic attachments snap on and off with just the right amount of effort – not so much it's a struggle, or requires the gripping of anywhere other than the dedicated stay-cool sections of the attachment, and not so little that there's a danger the tool will fall off mid-style.

The Attachment Learning tech worked as intended – in use, the Nural reliably remembered my last-used temperature and airspeed preferences. This feature will be useful for anyone who regularly uses a few different attachments for styling. Like many of Dyson's tech innovations here, it's not essential, but it does remove one of the annoying, fiddly parts of hair styling and streamline the process that little bit more. It's not just a gimmick. Exactly the same goes for the Pause Detect when the dryer is put down.

I also appreciate Dyson branching out past your standard diffuser-and-concentrator package to offer attachments for different hair types, although it has taken a bit of experimenting to figure out exactly how some of them work and what they're for (this Dyson community page has come in handy). The Flyaway attachment is a standout, using the same hair-bending Coanda airflow effect that the Airwrap is based on to flatten out flyaways and leave a smooth finish with absolutely minimal effort.

As someone with naturally slightly curly hair, I was also impressed with the redesigned Diffuser. Regular diffusers leave my hair super-frizzy, but the 'Dome mode', created by removing the central prongs, gave me smoother, more defined curls. (You can see how it works in the video above.)

Overall, minor niggle about the length of the handle aside, I really have no complaints about the Supersonic Nural's performance. It's by far the best hair dryer I've used.

How I tested the Dyson Nural Supersonic

• I used it as my primary hair dryer for a month
• I tested all the attachments and features

For this Dyson Supersonic Nural review, I used it as my primary hair dryer for a full month. I tried out all the various attachments and settings, using it to create a range of different styles and finishes. I compared it to other dryers I've used, including the original Supersonic, in terms of how long it takes to dry and style, and how easy it is to use.

GHD Duet Style: two-minute review

The GHD Duet Style promises to be a game-changer, because it can dry and style at the hair at the same time. In theory, it could make for worthy, somewhat more affordable alternative to the Dyson Airstrait (which launched after the Duet), but on test it falls a little short in places.

Throughout my trial, I tested the Duet Style on a range of hair states: soaking wet; damp, towel-dried hair; and second-day hair. Compared to my regular hairdryer, which takes my hair from wet to dry in around four minutes, the Duet Style took an almost painful 15 minutes – the slowest hair dryer I've ever used. (In comparison, in our Dyson Airstrait review, we found this drier-straightener was a genuine time-saver.)

The issue with the Duet Style is that because you have to section your hair and dry each section individually. Even then, it takes multiple passes over each strand to truly dry it effectively. If it takes this long on my long, thin hair, I dread to think how long it would take on thick or coily hair. It's not going to be troubling our best hair dryer guide any time soon. 

Using the Duet Style on damp hair took an average of nine minutes, while using it bring life back to my second-day hair took less than two. The latter has quickly become my favorite way to use the Duet Style. The hot air reaches 300F / 150C, while the plates heat up to 360F / 180C. Like all GHD stylers, there's only one temperature setting.

Once your hair's dry, pressing the Shine Shot button turns off the hot airflow and turns on the plates. After 20 seconds, you can then run the Duet Style over your hair like you would with standard straighteners to knock out any remaining frizz and add a dose of shine.

The styles created with the Duet Style last noticeably longer than they ever have when I've blowdried my hair in the past. I have naturally curly hair, and typically a hint of humidity sends it into a frizzy frenzy, but the Duet Style improved this. The only downside is that you have to sacrifice the volume, body and bounce you only really get from a traditional blow dry.

I'm also not a huge fan of the Duet Style's size and weight. It measures 16.7 x 12.8in / 42.4 cm x 32.5cm (H x W) and weighs 1.5lb / 675g. This makes the styler cumbersome to maneuver around your head and near-impossible to create flicks or curls, like GHD promises, significantly reducing the Duet Style's versatility.

This extra weight also means you have to hold the end of the tool for stability and to stop your arm from aching, but the styler has a tendency to get hot during use, making it uncomfortable to grip for long periods. On the plus side, the large size does allow you to tackle bigger sections of hair at once. 

Size and weight issues aside, the GHD Duet Style's controls are simple and easy to use and the fact it creates styles that last is a major selling point. If you're looking for a one-stop shop for drying and straightening your hair, and you're a patient person, the Duet Style could be a good option. However, if you value speed, maneuverability, and styling versatility, or you have thick hair, you might be better off sticking with your trusty hairdryer and straightener combo.

GHD Duet Style review: price & availability

• List price: $399 / £379 / AU $595
• Available: US, Australia, UK and Europe

The GHD Duet Style is available in black or white as standard, and at time of writing there's also a limited-edition Elemental Blue colorway, which forms part of GHD's recent Color Crush collection.

The standard model costs $399 / £379 / AUD$595, making it the most expensive GHD styler on the market. In the US, the Color Crush version costs the same as the standard model, at $399, yet in the UK and Australia the price for the blue model rises to £389 and AUD$605 respectively. All three regions sell the blue version with a leather storage case. 

You can additionally buy the black GHD Duet Style as part of a styling set in the US. This kit contains the styler, a 'lizard velvet' storage case and the GHD Sleek Talker heat protect spray yet still costs the same, at $399. 

Within the wider GHD range, the Duet Style most closely resembles the $269 / £209 / AUD$370 GHD Max in terms of design, and is closest in price to the $299 / £309 / AUD$500 cordless GHD Unplugged. Yet stands apart from all of its siblings, as well as the vast majority of the market because of its 2-in-1, wet-to-dry features.

The only other like-for-like styler wet-to-dry styler is the Dyson Airstrait. The Airstrait is available in the US and UK for $499.99 / £499.99 and is due to launch in Australia later in 2024. The Airstrait offers the same wet-to-dry features as the Duet Style but doesn't have the flat iron hot plates seen on the GHD model. 

The GHD Duet Style is available in the US, UK, Australia, Canada and across Europe, and is sold directly from the GHD website, but also via plenty of third party retailers. 

Given that the choice of wet-to-dry stylers is limited, and the GHD Duet Style is significantly cheaper than the Airstrait, despite featuring hot plates, it represents decent value for money. You're effectively paying for advanced, cutting-edge tech and innovation and getting a GHD hair dryer and flat iron styler for the price of one. That said, you could still a separate hair dryer and flat iron with change to spare, so it depends on your needs.

GHD Duet Style hair dryer review: design

• Large and heavy paddle-shaped design
• Easy to use controls
• Well-placed air vents 

The GHD Duet Style is notably larger and heavier than the average styler, measuring 16.7 x 12.8 in / 42.4 cm x 32.5 cm (H x W) and weighing 1.5lb / 675g. The hot plates each then measure 0.6 in / 1.7cm wide. This makes it a bulky piece of kit and not the easiest of stylers to move around the head. It also makes it a pain to store.

The plates sit either side of a central air vent on both the upper and lower arms of the styler. These vents are covered in a grid that disperses the hot air evenly onto your wet hair as you pass it through the dryer. There are then two thin air vents built into the arms of the Duet Style. These are used to dry the hair above and below the styler as it moves through the hair. A small but welcome, and smart, addition. 

Design-wise, the Duet Style closely resembles the GHD Max, thanks to its wide, paddle-shaped design, albeit with a much thicker handle. This handle is where the motor and filter for the drying element sits and this filter is attached to the Duet Style's 360-degree, 8.8ft / 2.7m cord. Its minimal, easy-to-use controls are then found on the top of the styler's arm.

These controls consist of a power switch surrounded by a white LED ring, above a Shine Shot button. The switch controls the dryer element of the GHD Duet Style and can be used on wet or damp hair. The Shine Shot button controls the hot plates and should only be used on dry hair. Both controls are accompanied by a short beep that signals that the styler is ready for use. I'm a big fan of this auditory feedback and I miss it when I use other stylers without it. 

The hot airflow on the GHD Duet Style maxes out at 300F / 150C while the plates operate at 180C / 360F. GHD stylers only ever offer one temperature setting. This is the optimum temperature, according to GHD, because it's hot enough to mold the hair into shape, while causing minimal damage.

While the GHD Duet Style has a built-in filter, it doesn't offer a cleaning mode (like the Dyson Airstrait) so you'll need to keep it free from dust and build-up over time. GHD recommends using a soft toothbrush to keep this filter clear. 

It may not be the most stylish, or compact styler, but the GHD Duet Style's design is well considered. It shares the premium look seen across rest of the GHD range and there are small touches and accents that elevate its appearance. 

• Design score: 3.5 out of 5

GHD Duet Style review: performance

• Slow drying times
• Difficult to maneuver and use for long periods
• Long-lasting styles 

The GHD Duet Style takes a bit of getting used to. Not just because it's unlike any styler I've used before, but because it goes against everything I'd ever been told about using stylers on wet hair. For my Duet Style review, I tested the styler on wet hair, straight from the shower; on damp towel-dried hair; and on second-day hair. 

My favorite way to use the Duet Style is on second-day hair. It brings my style back to life without having to rewash it, and it gives more precision than a traditional hair dryer without having to resort to straightening it or similar.

From wet to dry, the GHD Duet Style took significantly longer than it does with a regular hair dryer – almost 15 minutes compared to the average of four. If you have long, thick or coily hair, this could exceed 30 minutes or more.  Taking my hair from damp to dry then took, on average, nine minutes and produced a similar finish. 

These lengthy times are largely because you have to section the hair, and dry each section in turn. GHD advises that you hold the dryer near your roots for three seconds to dry the hair closest to your head before passing it over the lengths, which adds to this time. It then takes multiple, slow passes over each strand of hair to dry it effectively. I had hoped, after spending this long drying my hair, that I'd be ready to leave the house, but my hair lacked the shine and finish I'd have expected. 

Thankfully, the Duet Style's Shine Shot came to the rescue. Press the button, wait 20 seconds and the Duet Style becomes a flat iron styler. You then run it over your hair to knock out any remaining frizz and add shine.   

The biggest selling point of the Duet Style, however, is that whichever way I use it, my style lasts much longer than when I blow dry it. I have naturally curly hair and usually, as soon as it gets even a hint of humidity, it becomes frizzy and the curls return. This was noticeably improved while using the Duet Style. It isn't the cure for frizz, but it's close. 

This does come at the sacrifice of body and movement though. The root drying vents help add volume at the roots but you don't get the same movement or bounce as you do with a regular blow dry. What's more, there's not much you can do about this. The Duet Style is too large and unwieldy to move around the head easily, or twirl it around the hair in the same way you would with a barrel brush. No matter how hard I tried, I never managed to add flicks or curls or achieve the versatility that GHD promises.

Given the size and weight of the styler, it's also necessary to hold the end of the Duet Style while passing it over your hair to keep it steady and to manage the weight. This can get uncomfortable as the styler gets hot and you have to avoid the hot air coming out of the side vents.

It's not so hot that it burns you, but it's hot enough for you not want to hold it for long periods. There are strips of rubber edging to help with this but they're too narrow to really make a difference, and these rubber strips tend to attract a build-up of leftover heat protector and styling products easily. If there is one plus side to the Duet Style's large size, it means you can dry large sections of hair at any one time. Helping to counteract the long styling times.

Two-minute review

Dyson's latest haircare innovation is here, and ready to blow you away – literally. For the uninitiated, the Dyson Airstrait uses focused airflow to tame your tresses (much like the Dyson Airwrap), protecting you from potential heat damage incurred by using a combination of traditional hair dryers and straighteners. In that sense alone, it's easily one of the best hair straighteners I've ever used. 

Dyson may historically be best known for making some of the best vacuums, but in recent years its hair- and air care products have started appearing in TechRadar's best hair dryer and the best purifier rankings. Following the viral success of the Airwrap, the Dyson Airstrait is under a fair amount of pressure to live up to the multi-styler's legacy, and especially following the slightly lukewarm reception to the Corrale, Dyson's still-innovative but more conventional straighteners. All those efforts to master air engineering have clearly paid off; the Airstrait is pretty accomplished and a solid all-rounder, but it's got some flaws that make it far less useful for certain hair types and styling. 

Using a precisely angled (by 45 degrees) blade of focused airflow to simultaneously dry and straighten hair, the Airstrait managed to take my thick, wavy and porous hair from wet to straight in just 10 minutes – less than half the time it would take me to dry and straighten my hair, even if I was using the Dyson Supersonic and Corrale. It's worth noting though that it's pretty hard to achieve pin-straight locks; the Airstrait created more natural-looking results, which I personally prefer.

It's not just for wet styling either – the Airstrait also has a dry styling mode and a cool mode to set your style, though I will say the dry styling isn't quite as effective as wet.

As ever, though, the Airstrait falls victim to two of Dyson's cardinal sins: being overpriced and just a little impractical on account of its size and weight. There's no doubt it offers something fairly unique in the market – barring the ghd Duet Hot Styler, that is – but I'd say if you're gearing up to spend nearly $500 / £500, you're potentially better off getting an Airwrap and using its barrel or flyaway attachment to create a similar effect, depending on your hair type. 

It'd be remiss of me to not mention that although the Airstrait is a four-star product for me, that's largely down to my hair type. I can't speak for how it would work for coily or curly hair, for example. 

Dyson Airstrait review: Price & Availability

• List price: $329 / £289 / AU$465
• Launched in the US in May 2023, and UK in March 2024 

In case you missed the memo, Dyson's products are known for their high price tags, and the Airstrait is no different. At full price, it's $499.99 / £449.99 and is available directly from Dyson as well as at select third-party retailers such as Amazon.

The Airstrait launched in May 2023 in the US, but it has taken nearly a full year to hit the UK. As of writing, pricing and availability have yet to be confirmed for Australia, but I expect we'll see a release date before the end of 2024.

Now, there's no avoiding the fact this is an incredibly costly pair of tongs. In some territories they outprice Dyson's other hair straighteners, the Corrale ($499.99 / £399.99 / AU$699). 

Dyson Airstrait review: Specs

• Value: 3.5 out of 5 

Dyson Airstrait review: Design

• Chic, futuristic design with OLED screen
• Monstrously large plug and broad plates
• Fairly heavy for straighteners

Design-wise, the Dyson Airstrait is a real mixed bag. It's part retro, part futuristic aesthetically, resulting in a pair of tongs that look straight out of an 80s sci-fi movie in all the best ways – provided, of course, you like 80s sci-fi movies. 

Functionally, you've still got two plates that clamp together, which plug into the wall for power (here via a 6.6ft / 198cm cable). The key difference compared to a traditional straightener is that Dyson has swapped out hot plates for unheated panels, and on the underside there are two vents – that's where the air straightening magic happens. 

A thumb-sized OLED display on the main body shows you the styling mode, airflow and temperature settings. Below this, you'll find the five button controls: hot temperature, airflow speed, cool temperature, wet/dry mode and power. To me, the OLED screen is a bit unnecessary – I'd prefer a small light indicator and a slightly lower price tag, personally. 

There are two colorways currently available: bright nickel and prussian blue. It seems like Dyson is dropping its iconic fuschia colorway altogether, which I think is a shame. Still, I love the glossy finish and copper accents on the bright nickel model I tested.

At 1.18lb / 536g when held, they're pretty darn heavy for straighteners – just a touch lighter than the hefty 1.23lb / 560g Dyson Corrale. This does mean you could end up with some light arm-ache if you were using the Aistrait for a long period of time. Thankfully, the Airstrait makes pretty quick work of most hair types.

Even the PRCD plug for the Airstrait is pretty monstrous. This bulky component might be built with safety in mind, but my goodness it's an eyesore. On the plug are test and reset buttons to offer ground fault protection, which accounts for the seriously powerful engines whirring away inside the Airstrait. Just don't expect to be able to plug them into outlets with furniture backed onto them. 

• Design: 4/5

Dyson Airstrait Review: Performance

• Little-to-no hair snagging or sizzling
• Instantly heats up and delivers speedy results
• Shiny, silky hair, but not pin-straight

On test, I was pretty impressed with the Airstrait's performance. I've got thick, wavy and porous hair, so drying it can often be a bit of a pain, especially if I don't have time to let it air-dry a little first. 

However, with the Airstrait, I saved time on multiple fronts. For one thing, the Airstrait can handle fairly chunky segments of hair at once, all without snagging and pulling. I was pretty dubious of this claim prior to my testing (the Corrale promised much the same but I still find it's fairly easy to snag hairs if I'm not paying attention).

Then there's the drying itself. If you're slow and steady enough, the focused and angled blade of air generated by the Airstrait can dry a segment of my hair in just one pass, though I tend to give it a quick once over with a cool shot to set. 

It's worth noting that because of its bulky design, the Airstrait can't get right up to the root. That's fine for my naturally wavy hair, but might be an issue for those with more defined, tighter curls. 

Its wet mode offers three temperature settings (80C / 175F, 110C / 230F, and 140C / 285F) while dry offers two (120C / 250F or 140C / 285F), and there's also a boost mode.

The 45-degree angled blade of focused airflow is a pretty impressive feat of engineering, in more ways than one. For one thing, it heats the segment you're straightening impressively quickly, and there wasn't once in my multiple weeks of testing that I smelled the dreaded stench of burning hair. 

Plus, thanks to the angle of the airflow, the Airstrait doesn't disrupt the rest of your hair – or your face – while straightening, keeping you cool, calm and collected throughout your beauty routine. However, you can't really curl your hair as you can with standard hot plates, and it can be quite hard to create volume, especially given the issues with reaching the root of your hair. 

In just 10 minutes, my hair was silky, straight, and smooth, with minimal frizz and pretty impressive staying power. It's never quite perfect, but I struggle to achieve pin-straight results even with the best straighteners – plus I think a more natural straight look can be just as desirable. I did try it on dry hair, but I wasn't as impressed – it didn't seem to really do much beyond taming frizz and unmanageable flyaways.

The results lasted most of the day for me, keeping my hair relatively straight all the way through to the evening – but that's pretty standard for my hair type. When I tested on my partner's curlier Asian hair, I struggled to get it fully straight and noticed the results were slightly less shiny. If the styled hair got wet, damp, or encountered humidity, it became loosely curled again. This mirrors many customer experiences with curly, coily and frizzy hair – the Airstrait seems to work well, but doesn't offer the staying power of traditional hot plates.

Dyson has factored some pretty useful features into the design, too – in particular, the intuitive airflow adjustment and auto-timer. The former detects when hair is between the Airstrait's arms and adjusts the volume of airflow accordingly, and the latter cuts out the airflow when the arms have been left open for more than three seconds. 

Both these features can come in pretty handy, not least because the Dyson Airstrait is quite loud in use, registering 72 dB at its loudest while clamped around wet hair, and 63 dB when idle. That's still very impressively quiet for a hair dryer, though, and especially one packing this much power.. 

Overall, the Dyson Airstrait is a top performer for my very specific needs; it straightens wavy and slightly curly hair quickly and effectively, giving glossy and natural-looking results that by and large last the whole day. However, when used on curlier or coily hair, it's harder to achieve the same results you can with conventional straighteners.

How I tested the Dyson Airstait?

• I used the Dyson Airstrait as my main hair straightener and dryer for three weeks
• I used it to dry my hair from wet as well as to straighten my dry hair
• I have thick, wavy and porous hair

I used the Dyson Airstrait every time I dried my hair for three weeks, as well as its dry mode to touch up any unruly curls that set in overnight. I tested all of its modes and temperatures to gauge their effectiveness, as well as attempting different ways of using the Airstrait to style my hair.  

I also tried straightening my partner's thick, curly hair to see how performance varied between hair types. Additionally, I measured the decibel output to gauge how loud the Airstrait was in use. 

As well as testing haircare products for the past three years, I've been hair-obsessed since childhood; I've had long hair, short hair, colored hair and natural hair, all of which I've styled (and sometimes, disastrously, cut) myself with a wide variety of tools. I've used my own professional and personal experience to inform my testing.

Zuvi Halo hair dryer: two-minute review

Once dubbed the 'Tesla of hair dryers', the Zuvi Halo has gained a cult following across social media, as well as winning multiple accolades from industry experts – including being named one of TIME Magazine's Best Inventions. 

Instead of relying on hot air to dry hair, the Zuvi Halo uses a combination of targeted air flow with 'safe infrared light energy' to dry the water on the hair's surface. Said to have been inspired by the way the sun evaporates rainwater, it promises to boost hair hydration by 109%, shine by more than a third, and hair strength by 9%. 

The Halo offers five drying modes – Care, Fast, Soft, Style and Cool – and, depending on the mode you select, each adjusts the air speed and the intensity of the infrared light to suit different needs. For example, Fast prioritizes speed, while Care prioritizes hair health. Soft is best for people with sensitive scalps; the Style mode is designed to be used with Halo attachments, and Cool helps to set your style. 

You can't manually adjust the heat or speed settings to suit your specific hair, and this limits the level of control you have. However, there are three attachments available for the Halo: a Styling Concentrator, a Diffuser and a Gentle Air attachment, which add a degree of control and versatility. 

Making a decision over which mode to choose can be confusing; the Halo isn't as intuitive or easy to use as the majority of hair dryers. I always opted for the Fast mode because, for me, saving time is a priority. I found that my hair was frizzier and more unwieldy having used the Soft mode, and Care mode didn't dry as quickly as I'd like. Yet all of the modes were noticeably faster at drying my hair than with my regular Revlon One Plus, and my GHD Helios. 

The plus side is that this cuts down on styling time, especially in the morning. The down side is that I seemingly had to sacrifice shine in order to benefit from the speed. I often had to resort to using straighteners to calm the frizz and flyaways. Aside from adding time to my routine, this counteracted the stated hair health benefits of using the Halo. The finish was also in stark contrast to the brand's claims. 

That's not to say I wouldn't recommend the Zuvi Halo hair dryer. After three weeks of use, my hair health was noticeably improved. Once I'd become more familiar with the outcomes of the various modes, I valued the fact that I didn't have to mess around with different heat and speed settings. Plus, there's something novel and futuristic about the Halo dryer that sets it apart from the crowd, in a good way. In the many years I've been testing the best hair dryers, it's rare for a product to surprise me in the way the Halo did. 

It's just a shame that all of this next-level technology pushes the price of the Halo beyond the reach of so many, in addition to the fact that, for the price, the Halo isn't perfect.

Zuvi Halo hair dryer review: price & availability

• $349 / £329 for Halo + 3 attachments
• $329 / £309 for Halo + 2 attachments

The Zuvi Halo is available in two bundles. You can buy the Zuvi Halo hair dryer plus all three attachments – the Diffuser, Styling Concentrator and the Gentle Air attachment – for $349 / £329. Alternatively, if you don't need the Diffuser, you can buy a smaller, two-nozzle bundle for $329 / £309. It's not possible to buy the hair dryer on its own. 

Price-wise, the top-end Zuvi Halo bundle puts it on a par with the Dyson Supersonic. However, the Dyson ends up being better value for money because it ships with five attachments by default. This includes versions of the three attachments sold with the Zuvi Halo – Diffuser, Styling Concentrator, and Gentle Air attachment – plus a Wide-tooth Comb and Flyaway attachment.  

The Halo is available in the UK, US, Canada and across Europe, and is sold directly from the Zuvi Life website.  You can also buy it from Target in the US, and QVC in the UK. 

Zuvi Halo hair dryer review: design

• Four preset modes + Cool shot
• Faux leather handle feels premium
• Bulky attachments

If the price doesn't draw comparisons with the Dyson Supersonic, then design of the Zuvi Halo will – certainly at first glance. The Halo has a short, circular barrel and long handle. It measures 9.9 x 3.3 x 3.8 inches (254 x 84 x 98mm) and weighs 1.2lbs / 546g without any nozzles attached. 

At the front of the barrel is an air outlet surrounded by a circular pane of glass, behind which sit the infrared LEDs. At the rear of the barrel is the filter inlet, which is positioned above the four main mode icons. These modes are:

• Care: Balances speed with optimizing your hair health
• Fast: Prioritizes speed
• Soft: Reduces airflow and uses less light, for people with sensitive scalps
• Style: For use only with the attachments – airflow plus direction and intensity of light adjusts according to the nozzle attached
• Cool: Sets the style and adds shine

The Mode selection button and the Power switch sit further down the handle. Select a mode, and you'll see a small white LED light up below the corresponding button to show you it's currently selected.

As well as enabling you to toggle through the main modes, the Mode selection button also doubles up as Cool shot button on pressing and holding it. At the end of the handle is a 2.7m cord.

Unlike the majority of plastic dryers and stylers, the Halo is made largely from metal, with faux leather on the handle. This gives the hair dryer an extremely premium feel while also making it easy to grip. The white colorway and iridescent nature of the infrared lights also make the Zuvi Halo one of the most stylish hair dryers I've used.

Zuvi Halo hair dryer review: performance

• Fast drying times 
• Difficult to determine the best mode
• Mixed styling results 

To test the Zuvi Halo, I trialled each mode in turn repeatedly for a month, taking note of the time it took the hair dryer to dry hair, the resulting smoothness and shine, and how hair felt overall after use. 

Not surprisingly, the quickest mode was Fast mode – although it wasn't as speedy as I'd hoped. On this mode it took the hair dryer 5 minutes 50 seconds to take my long, thin, naturally wavy from wet to dry. And while my hair felt more voluminous than normal when drying with a hair dryer (as opposed to a hot brush), it felt rough and looked frizzy. In fact, my hair looks less frizzy when I let it dry naturally. A quick look at some online reviews has found that I'm in the minority in this regard; but since it was a common occurrence throughout my review period, rather than a one off, it could just be that this particular hair dryer just doesn't suit my hair. 

Next up was Care mode. This produced a much better finish than Fast mode; my hair was smoother without losing volume, but it took almost 45 seconds longer to get my hair from wet to dry. 

Soft mode lived up to its name, leaving my hair feeling soft and healthy; but again, frizz and flyaways were an issue, not to mention it took around 8 minutes to complete styling. 

The Zuvi Halo's best results were in Style mode with the Styling Concentrator attached. It took slightly longer than Fast mode to style my hair – 6 minutes, on average – but the extra time paid off because my hair was left feeling both softer and smoother. The Diffuser worked well at setting my curls without leaving them looking frizzy. I didn't quite see the need for the Gentle Air attachment, though, considering the Soft mode adequately reduces both speed and temperature; it worked well, but seems unnecessary. 

Although the Zuvi Halo hair dryer looks bulky, especially with the nozzles attached, it's surprisingly lightweight. In addition, the shorter barrel makes it easy to move around the head; even taking account of the longer drying times across the board, my arms never ached in use. 

In terms of noise, the Zuvi Halo is one of the quietest hair dryers I've tried, even on Fast mode. The highest decibels it recorded throughout my review period was 78 decibels on Fast mode. I could easily hear my music, and have a conversation with my son while drying my hair, which is rare.

Zuvi Halo hair dryer: two-minute review

Two-minute review

GHD is a styling pioneer. It was one of the first brands to release flat iron straighteners (featuring its iconic ceramic yellow plates) and has consistently led the way when it comes to styling tech. Today it sells a range of stylers from curling tongs to hair dryers, brushes, styling products, and even the wet-to-dry GHD Duet Style, yet it's still best known for making some of the best hair straighteners, and the latest to join this collection is the GHD Chronos. 

As a successor to the GHD Platinum Plus, which launched in 2018, the Chronos promises to be faster, smoother, and easier to use. GHD claims it halves frizz, boosts shine by 85%, and styles hair three times faster and, for the most part, it lives up to these claims.  

I hadn't realized how much the Platinum Plus pulled on my hair until I used the Chronos. It glided through my hair with surprising ease, and this not only made it easier to use, but it reduced the friction and potential damage to my hair. In turn, this noticeably decreased frizzing and left my hair looking smoother and shiny, both when it was straightened but also when I used it to create curls and waves.    

This styler is more compact, and with rounder edges than previous GHD straighteners, but the hot plates have stayed the same size. As a result, the Chronos is easier to store and travel with, but it also makes it more ergonomic, letting you create curls and flicks easily. In fact, the Chronos' ability to create curls effortlessly is its biggest selling point.

Yet despite these updates and upgrades, the Chronos still falls a little short. Firstly, the claims GHD makes about its improved responsiveness, speed, shine and more are either in comparison to naturally dried hair, the GHD Original, or on a small sample of consumers, which lessens the impact of those claims somewhat.

Secondly, while the speed, shine, and ease of use improvements I experienced were good, I don't feel like they were dramatic or impactful enough to warrant spending $329 / £289 / $AU465. The improvements between the Platinum Plus and Chronos, for example, were relatively minor on my long, thin hair. Decent, but not groundbreaking. 

And thirdly, GHD continues to only offer one temperature setting — 365°F / 185°C — across all of its stylers. GHD says this is because it's the optimum temperature for creating a style without damaging the hair and, for my hair in particular, this is true. However, for thicker, longer, and coily hair, this remains a major sticking point with the Chronos as it does the rest of the range.

The biggest problem I have, though, is that because GHD has continuously led the way with its styling technology, any new product needs to be different enough to warrant ditching one of its older models. The GHD Original, for example, is still a great styler and much cheaper. All of GHD's stylers are so well-built that they last for years, if not decades, and they hold their value — and that's before you look at the wider flat iron market and how much competition there is. 

If you've been looking for a new styler, have an older GHD or rival model, or regularly use a straightener to create curls, there's enough about the GHD Chronos to appeal. If you already have the Platinum Plus, need a styler with more heat options, or don't need any bells and whistles then $329 / £289 / AU$465 may be a step too far. 

GHD Chronos review: Price & Availability

• List price: $329 / £289 / AU$465

The GHD Chronos is the latest flat iron styler to launch from the British brand and is available in white, and black for $329 / £289 / AU$465. You can buy it directly from GHD in all three regions. 

In the US, the Chronos is available from Amazon, Walmart, and Ulta. In the UK, it's available via Lookfantastic, Selfridges, John Lewis, and Harvey Nichols. It's due to launch on Amazon UK on 15 April. In Australia, it's available at Adore Beauty.

The Chronos is the flagship flat iron styler in the GHD range but it's joined by a wider range of straighteners including:

• GHD Platinum Plus – a 1-inch flat iron styler and Chronos predecessor
• GHD Unplugged – GHD's first cordless flat iron, with 0.9-inch plates
• GHD Duet Style – a 2-in-1 dryer and styler
• GHD Original – the original, entry-level 1-inch GHD flat iron
• GHD Gold – a model that sits performance and price-wise between the Original and Platinum Plus
• GHD Max – 2-inch plates designed for longer, thicker hair
• GHD Mini – 0.5-inch plates for shorter hair

GHD Chronos review: Design

• Ceramic plates with ultra-glossy coating
• Heats up to 365°F / 185°C
• Redesigned curved barrel and wishbone hinge

At first glance, the GHD Chronos looks remarkably similar to the Platinum Plus and other straighteners in the range. The body of the styler is made from plastic with a matte finish, available in either black or white. There are two grey-silver ceramic plates fitted on the underside of each arm of the Chronos, above the power button which is surrounded by a white LED. At the bottom end of the styler is a metal wishbone hinge with a 360-degree, 2.7-meter swivel cord attached.

Yet look a little closer at the design and specifications and there are a handful of key differences. Firstly, the Chronos is smaller than previous GHD models, measuring 11.8 x 4.6 x 2.8 inches and weighing 1.63 lbs. The Platinum Plus, for comparison, measures 12.6 x 4.72 x 3.54 inches and weighs 1.65 lbs. Despite the Chronos' smaller form, the 1-inch plates have remained the same size.  

There aren't any temperature controls on the GHD Chronos. This is because all of GHD's hair tools are pre-programmed to only a single setting of 365°F / 185°C. GHD claims this is the optimum temperature for heat styling because it's hot enough to manipulate the bonds in the hair and set the style, but isn't so hot that it breaks the bonds completely and damages the hair. 

Features-wise, the Chronos uses what's described as "HD motion-responsive technology with a next-generation ceramic heater" to control heat to the plates. 

This is an upgrade to the ultra-zone technology seen on previous GHD stylers, and is said to be powered by an algorithm that identifies how the tool is being used. As you move and use the Chronos, its built-in algorithm understands the angle at which it's being held and the amount of hair in the plates. It then uses this to make sure the heat is evenly distributed. This promises to give you greater precision, and better heat consistency means better results. Ultimately, the technology has been designed to reduce the number of times you need to pass the plates over your hair, which saves you time and effort. 

As a result of these upgrades, and the ultra-gloss coating on the plates, GHD promises "the smoothest glide to deliver one-stroke styling with up to 85% more shine."

Other features include a 20-second heat-up time and a three-year warranty. The Chronos will also switch off automatically after 10 minutes if it's not being used.

GHD Chronos Review: Performance

• Quick to heat up
• One pass is enough to smooth hair
• Temperature needs to be reset every time

GHD makes a lot of bold claims about the performance of the Chronos. It's said to create styles that last 24 hours, three times faster than previous models. It claims to reduce frizz by half, enhance shine by 85%, and its re-engineered hinge and barrel have been “designed to craft high-definition curls and waves easily”.

In terms of speed, the Chronos took an average of 3 minutes and 15 seconds to straighten my hair. This isn't noticeably faster than the Platinum Plus, which takes 3 minutes and 25 seconds on average. Yet the three-fold increase is in comparison to the GHD Original and without one on hand, I wasn't able to fully test this.   

In terms of responsiveness, I didn’t notice much difference between the Chronos and other straighteners I’ve used. That said, I also didn’t have to pass the Chronos over my hair multiple times to achieve the desired finish, nor did I notice any hot or cold patches, so the best I can say about this is that it works as I'd expect.

Frizz was definitely reduced, and my hair did shine more than normal; as I have blonde hair it can be difficult to get a glossy finish due to the way it reflects the light. However, I had family members comment on the good condition of my hair, and I put that down to the Chronos.  

Sadly this style only lasted until I stepped outside at which point my hair quickly lost the smoothness and shine the GHD Chronos had created and the frizz returned, which took significantly less than the 24 hours promised. It should be noted that I have naturally wavy hair and it doesn't like any form of humidity, but I still had hoped the style would hold for a little longer than it did. 

Curling my hair using the Chronos took much longer – 9 minutes 45 seconds on average. This isn’t necessarily the Chronos’ fault; curling my hair with straighteners always takes longer than straightening it, and the Platinum Plus creates curls in a very similar time frame, but it’s worth noting.

The Chronos also glided through my hair without any friction as I twisted the styler to create the curls. This incredibly smooth experience, coupled with the smaller design and curved barrel, made curling my hair with the Chronos a hugely enjoyable experience. It was a noticeable improvement on the Platinum Plus, and any straightening iron I've ever used, and is where the Chronos really excels.  

Again, frizz was reduced, the curls were well-defined and smooth and they caught the light even more than when my hair was straightened. This style held for much longer and looked as good at the end of the night as it did at the start. 

For my thin hair, the single temperature offered on the Chronos was more than enough to create the style and hold it in place, until I left the house at least. 

Should I buy the GHD Chronos?
