Dyson Adds Active Cooling to Corrale Straightener and Combines Drying with Brushing in New AirSmooth
Dyson is introducing 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 week of expanded product activity 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 offered previews of 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 retains the original's flexing heated copper plates, which clamp hair and deliver heat at over 400 degrees Fahrenheit. What distinguishes the CoolShine 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 residual 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 thermal performance comparable to a corded straightener Dyson. The CoolShine's $329 price point sits well below the original's $500 launch price, a figure worth noting given the additional active-cooling engineering in the new model.
The AirSmooth dryer brush merges 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 claims the bristle configuration 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 control loops. 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 managed and 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 convergence 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.
The pricing of both new hair care products is notable. 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.
For technology professionals, the interesting engineering story here is thermal management. The CoolShine's water-filled cooling pipes represent a closed-loop heat extraction system operating within a handheld, battery-powered form factor at 400-plus degrees Fahrenheit. That is a non-trivial 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, and the bristle mechanics represent a mechanical engineering problem rather than a software one. The looped bristle structure that collapses under tension is a passive mechanical solution to snagging, a design choice that avoids adding active sensing to the brush head itself.
Both products are available this month.
