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: 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.
