And if change of hair color also became - or even more - simple than changing your shirt? Lauren Bowker proved it was possible at London Fashion Week . The British designer, who had already made clothes capable of changing color in response to room temperature or human body temperature, a Swaroski helmet changing color according to brain activity , a coat that reacts to external pollution has handed over the canopy, this time attacking our hair.

Red hair in the sun, black hair in the shade

After becoming famous in fashion, the designer decided to tackle our hair with a project called 'Fire'. She unveiled her first results at London Fashion Week, with the help of models from the agency Storm Models: depending on the outside temperature, their hair was red or black. This technique is based on a chemical reaction that occurs when heat (or cold) comes in contact with the pigments in the coloration.

Change color in a blow dryer

If the result is already surprising, Fire is in its infancy! The goal would be to improve the technology so that users can change color in no time: a blow of hair dryer would heat the pigments of the coloring, resulting in a chemical color and a change of color almost instantaneously! As for the colorations available, the pallet should extend well beyond red and black!

Tempted? It will take his trouble in patience. Not yet marketed, Fire should take some time to arrive in France!
