New Dyson wet-to-dry straightener

Dyson Airstrait UK review: Is the £450 Dyson hair straightener Airstrait worth it?

10th March 2024 | Author: Victoria Woollaston-Webber

There’s a new Dyson hair straightener in town that promises to straighten your hair and take it from wet to dry without hot plates – here’s everything you need to know about the styler in my Dyson Airstrait review

For many people, Dyson is synonymous with vacuums.

Yet in recent years the UK-born brand has made huge gains in the beauty market thanks to its growing collection of haircare tools and stylers.

In fact, the Dyson Airwrap is the most viral product on TikTok, while in China more people know Dyson for its hair dryers and stylers than its legacy in floor care.

Since the launch of the Dyson Supersonic hairdryer in 2016, the brand has ventured into the realms of curling, with the launch of the Dyson Airwrap in 2018, and cordless straighteners, with 2020’s Dyson Corrale.

Now, it’s combining two of these categories with the launch of its first wet-to-dry straighteners, the Dyson Airstrait UK.

Here’s everything you need to know about the Dyson Airstrait including how it works, why Dyson is launching it, the Dyson Aistrait price, and when it’s coming to the UK.

Before I dive into my hands-on Dyson Airstrait review and explainer, here’s how the new Dyson hair straightener fits into the wider Dyson hair care range, as well as the wider hair market.

Dyson Airstrait is the fourth hair styler to be released from Dyson since 2016. The other products, in order of release, are:

  • Dyson Supersonic: The Dyson Supersonic is a hair dryer that uses the company’s V9 motor with its Air Multiplier technology to dry hair quickly and quietly. As you can read in our Dyson Supersonic review, it remains one of the best hair dryers I’ve ever used.
  • Dyson Airwrap: The most versatile of the Dyson haircare products, the Airwrap is also its most popular. The main draw of the Airwrap for many people is the curling function that uses something called the Coanda effect to pull the hair towards the barrel and curl it in seconds. However, it comes with a range of attachments including smoothing brushes, and volumising brushes to suit different hair types and needs.
  • Dyson Corrale: Instead of using Dyson’s motor technology, the Dyson Corrale leans on its other market-leading technology – batteries. In our Dyson Corrale review, we explain how it uses floating hot plates to help straighten the hair while minimising damage.

The biggest competitor to Dyson, both generally speaking and when it comes to the Dyson Airstrait UK is GHD and its Duet Style.

  • GHD Duet style: The GHD Duet Style works similarly to the Dyson Airstrait. It looks like a pair of large hair straighteners and it uses hot air to take the hair from wet to dry. You can stop there, or you can switch to Shine Shot mode which switches the heat to low-temperature plates to smooth the finished look.

Dyson Airstrait: At-a-Glance

Is the new Dyson Airstrait worth it?mamabella | mamabella

What is the new Dyson hair straightener, the Dyson Airstrait? The new Dyson hair straightener is called the Dyson Airstrait – not the Dyson Airstraight as we first thought! It creates straight styles by taking your hair from wet to dry and, despite the fact it looks like a pair of straighteners, it does all of this using just hot air – no hot plates in sight.

How does the Dyson Airstrait work? The Dyson Airstrait looks like a pair of straighteners but it takes your hair from wet to dry only using hot air.

How is it different? There are hot brushes – like the Revlon One-Step Dryer and Volumizer Brush – that resemble hair dryers and are used to dry and style at the same time. Then there is the relatively new category of wet-to-dry stylers, including the GHD Duet. The GHD Duet Style uses hot air to remove moisture from the hair before hot plates help straighten and smooth the style. The Dyson Airstrait manages to combine the best of both worlds by providing enough hot air directed at very specific angles, coupled with tension rods and pressure, to create straight and bouncy styles.

Dyson Airstrait UK price: £449.99

Dyson Airstrait colours: Prussian Blue and Copper; Nickel and Copper

Dyson Airstrait UK release date: The Dyson Airstrait UK release date was 31 January 2024.

How does Dyson Airstrait work?

Dyson Airstrait wet-to-dry straightener designDyson

The Dyson Airstrait UK offers two main styling modes as well as several other features that help you complete your look. These include:

  • Wet Mode
  • Dry Mode
  • Root Drying Mode
  • Cool Shot

You can switch between these modes using a panel of controls found in between where the two arms meet the hinge. Above this wet-to-dry control are two buttons – one red, one blue – that let you increase or decrease the temperature when in Wet Mode. The Cool Shot button then completes the button line-up.

Above these buttons is a display that shows you, at a glance, which mode you’re in as well as the temperature you’ve selected as you move up or down the temperature settings. And within the drying modes, you can choose between low flow and high flow.

How to use Dyson Airstrait UK: Wet Mode

Dyson Airstrait in Wet ModeDyson

In Wet mode, a steady and controlled stream of hot air is directed onto the hair as you pass over it with the Airstrait styler. In this mode, you can set the styler to one of three different temperature settings:

  • 80°C (175°F)
  • 110°C (230°F)
  • 140°C (285°F)

As you’d expect, Wet mode is used for drying your hair after it’s been washed (or if you’ve made it damp in order to restyle.)

How to use Dyson Airstrait UK: Dry Mode

How does the Dyson Airstrait workDyson

In Dry mode, the flow of air works in the same way as in Wet mode but the temperature options include 120°C (250°F) or 140°C (285°F). You can also blast your hair with hotter air via a top-up “boost”.

Dry mode is used to help style day two (or three/four in my case!) hair without having to rewash it. Before the Dyson Airstrait, you’d either have to dampen your hair again or use a pair of standard straighteners to create the desired style.

In my experience, the latter can often leave the hair looking limp and flat – especially if you prefer styles with more body and movement – while the former can accentuate any grease that’s built up overnight.

Dyson promises that the Airstrait on Dry mode creates naturally straight styles without sacrificing body and movement.

Dyson Airstrait technology

Dyson Airstrait circuit board and technologymamabella | mamabella

To get more technical, the Dyson Airstrait achieves all of the above thanks to several engineering features.

Firstly, it’s powered by Dyson’s Hyperdymium motor. This motor has been specifically engineered to be small – it measures just 27mm and fits into the handle of the Airstrait – and light, while also being powerful enough to handle what Dyson wants its hair care tools to do.

Within this motor, a 13-blade impeller spins up to 106,000rpm, propelling 11.9 litres of air through the machine every second. This is said to generate up to 3.5kPa of air pressure.

This air is then funneled across the Airstrait through two 1.5mm apertures to create two high-velocity downward blades of air that are angled at 45°. At which point the blades converge to create a single focused jet of air.

Dyson told me that this is the ideal angle because it helps create enough downward force – along with the air pressure – to straighten the hair as it dries, without causing the hair to fly up and out of the arms.

Elsewhere, the Dyson Airstrait straightener – like with the other hair care products in the Dyson range – use glass bead thermistors to measure the temperature of the airflow 30 times per second to prevent heat damage and protect hair’s natural shine. This data is sent to a microprocessor which regulates the heating element, ensuring airflow doesn’t exceed the temperature required.

Dyson Airstrait UK review

For my Dyson Airstrait review, I spent time with the device at a launch event in October. I was given the chance to use the styler on both damp and dry hair.

Dyson Airstrait UK review: Design

Dyson Airstrait review design and ease-of-useDyson

The first impression of the Dyson Airstrait is that it’s a chunky piece of kit.

Design-wise it looks almost identical to a pair of straighteners, with two arms and a hinged connector. However, it’s a lot larger than what I’m used to with standard straighteners.

As a result, we’d expected it to feel bulky and heavy in the hand but it’s surprisingly lightweight and easy to hold. Once you explore all the features, and learn more about the technology that’s packed inside too, the extra size also makes sense.

I’m glad it’s so big because the performance of the Dyson Airstrait seems to benefit greatly from having this extra space and heft.

Where you’d usually find hot plates on a standard pair of straighteners are air vents in which hot air is directed over the hair as the styler is passed over it.

You still need to section out the hair and clamp it gently between these chambers, but instead of hot metal, you get concentrated hot air.

To create the tension needed to create a smooth style, there are two so-called tension bars – one is fixed into position, and the other floats and flexes with your hair as it moves from root to end.

Speaking of roots, the Dyson Airstrait also has a small external drying vent that allows you to blast your hair from above with the Airstrait positioned on its side. This is called the Root Styling Mode and allows you to either remove any excess moisture from the roots, add volume by drying it from below, or add shine by blasting cool air over the hair to close the follicles and reduce frizz.

Dyson Airstrait UK review: Ease-of-use

You physically hold and use the Dyson Airstrait in the same way, regardless of whether you’re hair is wet or dry.

Section a small piece of hair, clamp the Airstrait at the roots and slowly pass it over the hair to remove the moisture. It only took two passes over my hair to go from wet to dry on the highest temperature setting. If your hair is thicker, the section of hair is large, or you use a lower temperature, this will vary.


One small, yet significant feature that we like about the Dyson Air Strait is the fact its motor responds to movement.

For instance, if you’ve straightened one section but want to put the Airstrait down while you sort out the next section, the new Dyson hair straightener Airstrait automatically switches off when it’s placed on the side.

When you pick the Airstrait back up again, the motor kicks back in and the temperature and heat settings are as they were before.

Dyson told me that the temperature settings on the Airstrait have been engineered to maximise the finish while minimising heat damage.

I should add that when I say “wet”, I actually mean towel-dried. It’s not advisable to use the Airstrait on soaking wet hair because it will take you longer to dry the hair and thus subject it to extra, unnecessary heat.

If you find that the roots still aren’t dry enough, or you can’t get the Airstrait close enough to knock out all the moisture, then you close the arms, hold the styler on its side, and select root drying mode.

You can then move it over your roots like you would a regular hair dryer.

If you then combine this drying mode with cool shot, you can set your straight style with cold air.

I imagine that you could also use the root drying feature to remove excess moisture from the hair generally, if you want to dry it more than you can with a towel.

Dyson Airstrait UK review: Features and controls

The buttons on the control panel give you options as to how fast or hot you want the airflow.

For instance, pressing the button that has a water droplet on it switches the Dyson Airstrait between Wet mode and Dry mode.

When in Wet mode you can use the temperature buttons to increase or decrease the temperature based on your hair type, or how dry your hair already is.

  • The lowest temperature of 80°C (175°F) works great if you have naturally straighter hair, if your hair is fine and prone to breakage, or if it dries quickly.
  • For straight and wavy hair types, of medium thickness, you’ll likely find that 110°C (230°F) is hot enough to dry and style the hair with the Airstrait without having to pass it over your hair too many times.
  • For thicker hair, and curly hair types, there is then a maximum temperature of 140°C (285°F).

That’s not to say you can’t use different settings, but these will likely be the optimal settings to combine effectiveness with protection.

When in Dry mode, the controls are similar but instead of three temperature settings you get to choose from two: 120°C (250°F) or 140°C (285°F). The lower setting worked well on my fine hair, but thicker hair may require more heat to get the same results.

Another thing to note with this new styler is that it’s quiet. Similar to how the Supersonic and Airwrap sound, it was easy to chat with Dyson’s stylist who was helping me test out the Airstrait mid-style without either of us shouting.

Dyson Airstrait UK review is it worth it?Dyson

But what about the results? My hair was noticeably straighter and smoother after using the Dyson Airstrait. It also felt softer. What’s more, it took mere minutes to achieve this.

It’s a classic case of I didn’t realise I needed a product like this until I tried it.

As with all Dyson products, the Airstrait price is a sticking point. I recently interviewed Sir James Dyson and asked him to comment on why Dyson products are so expensive.

He told me: “Our priority at Dyson is creating high-performing products that are built to last and use energy efficiently. Years of research, testing, and development go into making each Dyson machine, and our commitment to engineering pioneering products that work differently and perform better remains our focus. Dyson machines are durable, and our prototypes are engineered to withstand thousands of hours of testing – which means thousands of hours of use.

“We make massive investments in technology we believe in, and the price of Dyson products reflects this.”

When you look at the attention to detail and performance of the Dyson Airstrait, I’d definitely say the Airstrait is worth it – if you can afford it. Sadly, it’s likely to be out of reach for many people and this is a shame because it really needs to be seen and experienced to be believed.


Dyson Airstrait vs GHD Duet Style

We detail more about the two products in our full Dyson Airstrait vs GHD Duet Style feature but to summarise:


  • Both brands describe their respective tools as wet-to-dry stylers.
  • Both resemble straighteners, albeit with much larger and thicker designs.
  • Both have hot air vents fitted along the inside of the chambers.


  • The Dyson Airstrait offers two modes – Wet and Dry – and only relies on hot air to style your hair.
  • The GHD Duet Style offers a Wet mode, in which hot air removes the moisture from the hair. Once the hair is dry – and only when it’s dry – you can switch to Shine Shot mode. This turns off the hot air and turns on two hot plates which work in the same way as the plates on previous GHD straighteners, such as the GHD Platinum Plus, to straighten the hair.

Dyson Airstrait FAQ

Below we answer some of the key questions about the Dyson Airstrait.

When is Dyson Airstrait coming to UK?

The new Dyson hair straightener Airstrait is coming to the UK on 31 January.

People who have signed up for early access can buy the new Dyson straighteners a day earlier on 30 January.

What is the Dyson Airstrait UK price?

The Dyson Airstrait UK price has been revealed as £449.99.

Can you use Dyson Airstrait on dry hair?

Yes! You can use the Dyson Airstrait on dry hair in Dry Mode.

In Dry mode, the flow of air from the Air Strait is heated to either 120°C (250°F) or 140°C (285°F) and this is hot enough to smooth and gently restyle your hair without wetting it first.

You can also blast your hair with hotter air via a top-up “boost”. This is particularly useful for more stubborn or difficult-to-style hair, like the hair around your face.
