Dyson goes ‘supersonic’ with first hair dryer

British technology brand Dyson has launched a hair dryer that is said to offer a fast, but focused, airflow and help protect hair from extreme heat damage.

The Dyson Supersonic hair dryer, which took four years and 103 engineers to develop, is the result of a £50 million investment by the British company, including the building of a bespoke, state-of-the-art hair laboratory.

Dyson engineers studied hair from root to tip, in order to understand how it reacts to stress and how to keep it healthy and how to style it.

The Dyson Supersonic is powered by the brand’s patented V9 digital motor, which is small enough to be positioned in the handle, rather than the head, of the hair dryer. This means the product is engineered for balance in the hand, said Dyson. Most conventional hair dryers have the motor in the head of the machine.

Said to use a fast, but focused, airflow, the Dyson Supersonic intelligently controls the temperature to help protect hair from extreme heat damage.

A glass bead thermistor measures the temperature 20 times a second and transmits the data to a microprocessor, which intelligently controls the patented double-stacked heating element.

The volume of the air drawn into the motor is ‘amplified’ by three, creating a focused jet of air, which is angled at 20 degrees for controlled, precise drying and styling. This allows the user to dry and style their hair at the same time.

Said Sir James Dyson: “Hair dryers can be heavy, inefficient and make a racket. By looking at them further, we realised that they can also cause extreme heat damage to hair. I challenged Dyson engineers to really understand the science of hair and develop our version of a hair dryer, which we think solves these problems.”

The Dyson Supersonic hair dryer will be available from June at, retailing for £299.
