Video interviewing women about hair damage

Hair damage can be invisible. But not to us.

We took a closer look

We found that damaged hair doesn't always look it. Over time, extreme heat affects the cortex, making hair weak, brittle and easier to break. Sustained cuticle damage drastically reduces hair's ability to reflect light, affecting shine.

Damaged hair decreases shine

When hair is exposed to extreme temperatures, small 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. Less damaged hair reflects more light in a single direction, so it appears shiny.

Glass bead thermistor

With a glass bead thermistor and microprocessor carefully controlling a double-stacked heating element, the temperature is measured 20 times per second. The Dyson Supersonic™ hair dryer protects your hair from extreme heat damage.

Powerful airflow. Controlled heat.

We found that effective - and safe - drying requires controlled heat balanced with powerful air. Only the Dyson digital motor V9 had the power to dry hair fast, without relying on extreme heat. And because it's so small, it could fit in the handle, allowing a better balance in the hand.
