Dyson's New Hair Straightener Cools Your Hair as It Styles

Dyson is launching two new hair care products this month: the Corrale CoolShine straightener at $329 and the AirSmooth dryer brush at $249. The announcement comes during a busy week for the company, which also added a camera-equipped electric toothbrush to its lineup, and follows its "Dyson Unveiled" event in Berlin on September 3, 2026, where it previewed upcoming products The Verge.

The Corrale CoolShine is an upgrade to Dyson's original Corrale straightener, which launched in 2020 at $500 after seven years and $32 million in development. The new model keeps the original's heated copper plates, which clamp hair and deliver heat at over 400 degrees Fahrenheit. The big addition is an active cooling system: small water-filled pipes pull excess heat away from your hair as it passes through the plates, so each strand gets heated, straightened, and cooled in one pass. Dyson says this leaves hair smoother, softer, and cooler to the touch right after styling The Verge.

The original Corrale was notable for working without a cord, running on a battery that delivered 30 minutes of styling time at heat levels comparable to a plug-in straightener Dyson. The CoolShine's $329 price is well below the original's $500 launch price, which is notable given the new model adds a whole cooling system on top.

The AirSmooth dryer brush combines the air technology from Dyson's Supersonic hair dryer line with a built-in brush. The brush head has a teardrop shape meant to add volume, and it uses two types of bristles arranged in loops that give way under tension to release strands, reducing snagging. Dyson says the bristle design also makes it more comfortable on the scalp. A smart heat control system checks and adjusts the temperature 100 times per second, aimed at reducing frizz and limiting heat damage The Verge.

Both products follow a familiar pattern for Dyson in the beauty category: take a standard appliance, rework how it handles heat or airflow, and stand out through better materials and smart sensors. The original Corrale's flexible copper plates were the key difference in 2020. The CoolShine adds a cooling layer on top of those same plates, treating heat not just as the thing that styles hair but as something to actively remove once it has done its job.

The AirSmooth targets a different goal: combining drying and brushing into one tool. Dyson's hair styling lineup already includes an attachment that straightens wet-to-dry hair using fast airflow, and a one-touch curling feature in its multi-stylers Dyson. The AirSmooth extends that same idea into the blowout category, for people who want a smooth finish without drying and brushing separately.

Dyson's move beyond vacuums and fans into personal care has been gradual but steady. The Dyson Zone headphones, announced in 2023 after five years of development, combined noise cancellation with on-the-go air filtration, capturing 99% of particle pollution as small as 0.1 microns and using potassium-enriched K-Carbon filters to target acidic gases such as NO2 and SO2 Dyson. The camera-equipped toothbrush announced earlier this week extends that same approach into oral health.

At $329 and $249, the CoolShine and AirSmooth are priced in the mid-to-upper range of the premium styling tool market but below the $500 the original Corrale cost. Whether the cooling feature in the CoolShine and the combined drying-and-brushing approach in the AirSmooth actually improve hair health is something consumers and independent testers will need to assess. Dyson's claims about reducing heat damage have generally been backed by real sensor and materials work, but the company's marketing tends to simplify complex heat dynamics into easy-to-digest language.

In my view, the most interesting story here is the engineering. Fitting a water-based cooling system into a handheld, battery-powered device running at over 400 degrees Fahrenheit is genuinely difficult. Doing it at a lower price than the original Corrale suggests Dyson has improved its manufacturing processes over the past six years.

The AirSmooth's temperature checks, 100 times per second, match the approach Dyson has used in its Supersonic dryers since they launched. The bristle design is a simpler, mechanical solution rather than a software one: the loops give way under tension to prevent snagging, without needing electronic sensors in the brush head.

Both products are available this month.
