Dyson Adds Active Cooling to Its Hair Straightener and Launches a Dryer Brush Combo
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 health and beauty lineup, and follows its "Dyson Unveiled" event in Berlin on September 3, 2026, where it previewed next-generation machines ahead of launch The Verge.
The Corrale CoolShine is an upgrade to the original Dyson Corrale straightener, which launched in 2020 at $500 after seven years and $32 million in research and development. The new model keeps the original's flexing heated copper plates, which clamp hair and deliver heat at over 400 degrees Fahrenheit. What sets the CoolShine apart is an active cooling system: water-filled pipes draw excess heat away from the hair as it passes through the plates, so each strand is heated, straightened, and cooled in a single pass. Dyson says the design reduces leftover heat exposure, leaving hair smoother, softer, and cooler to the touch after styling The Verge.
The original Corrale was notable for its cord-free operation, powered by a 4-cell lithium-ion battery delivering 30 minutes of styling time at heat levels comparable to a corded straightener Dyson. The CoolShine's $329 price sits well below the original's $500 launch price, a notable shift given the additional active-cooling engineering packed into the new model.
The AirSmooth dryer brush combines the airflow technology from Dyson's Supersonic hair dryer line with a purpose-built brush attachment. The brush head uses a teardrop-shaped design intended to create volume, and it carries two types of bristles arranged in a looped structure that collapses under tension to release strands, reducing snagging. Dyson says the bristle layout also improves scalp comfort during use. An intelligent heat control system adjusts temperature 100 times per second, aimed at reducing frizz and minimizing heat damage risk The Verge.
Both products fit a recognizable pattern in Dyson's approach to the beauty category: take a well-established appliance function, reengineer the core thermal or airflow mechanism, and differentiate through materials science and sensor-driven controls. The original Corrale's flexing copper plates were the differentiator in 2020. The CoolShine adds a thermal management layer on top of that same plate technology, treating heat not just as the styling input but as something to be actively removed after it has done its work.
The AirSmooth occupies a different niche: combining drying and brushing into a single tool. Dyson's broader hair-styling portfolio already includes the Air straightener 2x attachment, which straightens wet-to-dry hair using high-velocity airflow, and a one-touch i.d. curl sequence feature in its multi-stylers Dyson. The AirSmooth extends that same combination logic into the blowout category, targeting users who want a polished finish without separate drying and brushing steps.
Dyson's expansion beyond its core vacuum and fan business into personal care and wearables has been incremental but persistent. The Dyson Zone headphones, announced in 2023 after five years of development, paired active 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 engineering-to-personal-care pipeline into oral health.
At $329 and $249, the CoolShine and AirSmooth sit in the mid-to-upper range of the premium styling tool market but below the $500 ceiling the original Corrale established. Whether the active-cooling feature in the CoolShine and the integrated drying-brushing approach in the AirSmooth translate into meaningful improvements in hair health outcomes is something consumers and independent testers will need to evaluate. Dyson's engineering claims around thermal damage reduction have generally been grounded in real sensor and materials work, but the company's marketing language tends to compress complex thermal dynamics into consumer-friendly shorthand.
The broader context here is about thermal management. The CoolShine's water-filled cooling pipes are essentially a closed-loop heat extraction system, operating inside a handheld, battery-powered device at 400-plus degrees Fahrenheit. That is a serious thermal engineering challenge, and the fact that Dyson has packaged it into a consumer device at a lower price than the original Corrale suggests manufacturing process improvements in the intervening six years.
The AirSmooth's 100-times-per-second temperature feedback loop is consistent with the control systems Dyson has used in its Supersonic dryers since that product's introduction. The bristle mechanics, meanwhile, are a mechanical engineering problem rather than a software one. The looped bristle structure that collapses under tension is a passive solution to snagging, a design choice that avoids adding electronic sensors to the brush head itself.
Both products are available this month.
