The Dyson digital motor V9

Uniquely positioned in the handle, the Dyson digital motor spins on average 6 times faster than other hair dryer motors at one inaudible frequency – yet is a third of the weight¹. The thirteen-blade axial flow impeller generates 3.5kPa of pressure, propelling 13 litres of air up to the amplifier every second.

This clever microprocessor quickly calculates instructions and adjusts the double-stack heating element.

Damaged hair scatters light,
leaving it dull

When hair is exposed to extreme temperatures, pores can begin to form within the strands. When light hits these pores, it scatters in all directions. This can reduce reflected light, decreasing shine.

A comparison of damaged hair's ability to reflect light with that of healthy hair

Hair that’s less damaged is better
at reflecting light, making it shine

The Dyson Supersonic™ hair dryer uses intelligent heat control to maintain Dyson’s optimum temperature, helping to prevent extreme heat damage. Less damaged hair reflects light in a single direction, making the hair appear shiny.
