Rethinking the hair dryer

“As engineers, we have to see beyond existing technology and ask, ‘Is there a better way?’ Bulky motors have held back hair dryer design. Developing our smallest, lightest digital motor meant we could change that.”

Steve Courtney


Senior Engineer

To solve the motor problem, Dyson built their own hair lab

Dyson started by constructing their own hair laboratory within their Research and Development facility in Malmesbury, England.

Airflow precisely where you need  it.

With the Dyson Styling concentrator, you can shape your hair one section at a time – without worrying about disturbing the rest. See a stylist put it to the test.

The root of the problem.

Damaged hair doesn’t always look it. The effects of thermal, mechanical or chemical damage can take months to appear, whether it’s split ends, breakage, less shine or diminished style retention. Using extreme heat to style, like some conventional technology, can cause irreversible damage. Drying without extreme heat is key.

“Our testing showed a clear correlation between healthy and shiny hair. To keep hair looking healthy, it has to be protected from extreme heat.”

Engineers, Trichologists, Scientists… and a champion hair stylist.

Akin Konzi, four-time winner of British Hairdresser of the year, thought that hair dryers should work better too. Bringing decades of styling experience to our hair laboratory, he challenged Dyson engineers and scientists every step of the way – putting our prototypes through their paces.

Powerful airflow.
Controlled heat.

Effective drying requires a combination of heat and air. The combination of Intelligent Heat Control and the powerful Dyson digital motor V9 enabled us to dry hair fast without exposing hair to extreme heat.

Fail. Fail again. Fail better.

Over the five years of development, Dyson built 600 prototypes. 599 of them were failures. But each one taught them something; how they could make the Supersonic better. At times, they had to go back to the drawing board. But every iteration was an improvement. Every prototype was closer to being an invention.
