Dyson introduces liquid-cooled straightener to limit hair damage
Dyson has unveiled two new hair care products, the Corrale CoolShine straightener and the Airsmooth dryer brush, expanding its beauty range days after launching a camera-equipped electric toothbrush. The straightener's key innovation is active liquid cooling, intended to reduce residual heat exposure and resulting hair damage, addressing a common concern with high-heat styling tools. The launches reflect Dyson's continued push into premium personal care devices that combine engineering-led heat management with claims of reduced damage.
The £Corrale CoolShine costs $329 and builds on the original 2020 Corrale's flexing heated copper plates, which apply heat above 400°F, by adding water-filled pipes that draw excess heat away from hair immediately after styling. The $249 Airsmooth dryer brush combines Dyson's Supersonic drying technology with a teardrop-shaped brush using looped, anti-snag bristles designed to reduce hair breakage and improve scalp comfort, alongside a heat control system that adjusts temperature 100 times per second to limit frizz and heat damage.
In short
- Dyson launches Corrale CoolShine straightener with liquid cooling pipes
- $329 straightener actively cools hair after heat styling to cut damage
- $249 Airsmooth dryer brush uses anti-snag bristles and rapid heat control
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Dyson’s active cooling and rapid temperature control could help reduce the time hair remains exposed to high heat, while the brush’s anti-snag design may lessen breakage. For people who style their hair regularly, these features could offer a practical way to manage damage without giving up heated styling.
The case against
The products still rely on heat, and the straightener’s plates operate above 400°F, so cooling afterwards may not prevent damage caused during styling. The benefits are also claims about premium-priced devices; consumers may reasonably want independent evidence that they reduce damage enough to justify their cost over lower-priced tools or gentler styling methods.
Explained simply
Dyson is a British technology company known for household appliances such as vacuum cleaners and hair care tools. Its beauty products use heated air or plates to dry and shape hair, and are generally sold at premium prices.
Heat can help style hair, but repeated or prolonged exposure may leave it dry or damaged. Hair tools therefore often include temperature controls or other features intended to manage heat, though their effectiveness can depend on how they are used.
The Corrale is a straightener, which shapes hair between heated plates; Dyson’s original version, launched in 2020, used flexible copper plates. The Airsmooth is a dryer brush, combining airflow and brushing to style hair, and both products reflect Dyson’s effort to apply its engineering approach to personal care.
