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.

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.  

Should I buy the Zuvi Halo hair dryer?

Buy it if...

Don't buy it if...

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?

Buy it if...

Don't buy it if...
