Dyson just revived its Corrale straightener — and by shrinking it down and adding an ingenious cooling attachment, it's turned it into a tool I'm actually excited about

Dyson has launched an updated version of its 2020 Corrale straightener

The brand has also unveiled a hot brush called the Airsmooth

In recent years, Dyson's hair gadget efforts seem have been mostly focused on its Airwrap styler and Supersonic hair dryer lines. So when I was invited to a showcase of the brand's new launches, I was expecting, perhaps, some cool new attachments or an upgraded Supersonic. I was equal parts surprised and pleased to see something altogether more novel.

There's a brand new tool — which I'll get into in a minute — as well as a surprise second-gen version of the Corrale straightener, called the Corrale Cool Shine. If that name isn't ringing any bells, I don't blame you. The original Dyson Coralle came out in 2020 and never quite managed to set the haircare world alight.

I tried a Corrale out at the time and although I didn't hate it, it didn't make it into my regular styling routine. So I was especially pleased to see that the surprise second gen has tweaked or removed my least-liked features, and added some more that I'm genuinely excited to use.

One key feature of the original was that it was cordless. That's all well and good, but the knock-on effect was that it was also really very heavy and chunky. The Corrale Cool Shine is not cordless, and as a result it can be nice and streamlined and lightweight. I'm very happy with this about-turn; the new, compact shape is much more comfortable to hold, and easier to direct precisely.

The flexible plates from the first-gen version are still present here. They have to be, really — these are what 'corrale' the strands of hair, applying gentle pressure to, theoretically, allow for effective straightening at lower temperatures.

However, they've been downsized in line with the general shrinking of the straightener, and are slimmer in width. In their new format, they look much less likely to snag on strands of hair, as the previous version could sometimes do.

That's the 'Corrale' covered, but where does the 'Cool Shine' come in? This refers to a unique-to-the-market cooling attachment. It comes in the form of a pair of frames that slide over each of the hot plates, and clip in place. They feature a heat-extracting copper pipe that contains water and is designed to help remove residual heat from hair.

So the central plate gets hot as usual, and then the bars either side of the plate pull the heat away immediately, helping you avoid heat damage. Dyson promises "hair that is cooler to the touch during and after styling, with a smoother, softer feel".

When it was initially announced, it sounded like kind of cold plumbing system, but speaking to a Dyson representative at the product showcase, I learned the system is subtler and more complex.

The tube has just a 'bead' of water in it — if you're envisaging cold water running through it, that's not the case — and it will absorb some of the heat of the plates as you style, so don't expect those bars to remain cold as you style. I'd be very interested to try it out for myself to see how much of a difference these plates make in practice.

There was a Dyson Corrale Cool Shine being demoed at the event, and I was very impressed at how it managed to take the model's coily hair to perfectly smooth with an incredible glassy finish — but the kicker is that the stylist (and Dyson rep) wasn't using the Cool Shine attachment.

The representative explained to me that the frame is removable to allow for precision styling, as well as in instances where you need to get right up to the root. Both were required here.

A final welcome touch is that Dyson has added universal voltage, so you'll be able to take the tool away with you when you travel abroad.

The other new gadget is the Dyson Airsmooth brush dryer. This is a fairly traditional hot brush, for creating bouncy blowouts, but — of course — there's a bit of a Dyson twist.

The engineers have added two different types of bristles: some with loops at the top, and some with open bases. The former are engineered so they provide the right amount of tension for a smooth finish, without snagging on a range of different hair types. The latter are meant to diffuse and control the airflow for less turbulence and less frizz.

Dyson has given the Airsmooth a teardrop profile, to enable you to get closer to the root. I've seen this before, on the Shark Glam, and it works well there. There's also intelligent heat control keeping temperatures stable, and again, there's universal voltage — good news for your holiday hair.

The Dyson Corrale Cool Shine straightener will have a list price of

The Airsmooth dryer brush goes on sale from Dyson US and Dyson UK today (September 8) in the US, with the Corrale Cool Shine joining it on September 15.

At Dyson Australia, the hot brush is already on sale (launched September 4) and the straightener will arrive in November.
