Game-changing beauty

A dye that changes hair colour according to temperature is now a reality

“Magic is only science that we don’t understand yet,” said Lauren Bowker, founder of The Unseen—a London-based innovation, product development and technology licensing company behind the colour-changing hair dye—in an interview with Forbes. Yet, magical is probably the word that springs to mind when one sees the new hair dye by The Unseen in action:  

By colour-changing, we don’t mean hair colour that fades from dark to light, but one that repeatedly changes from one colour to another as it reacts to air and body temperature—if you blush for example, your hair will also change. To achieve this, Bowker altered molecular bonds so that when they are introduced to a certain temperature, a chemical reaction will take place to induce the different hair colour. The concept was inspired by a scene in The Craft, where the teenage witch casts a spell to change her hair colour.


Called Fire, the semi-permanent hair colour that gives one environmentally responsive hair made its debut at the recent London Fashion Week. It is not available on the market yet, but The Unseen aims to license it out to a haircare brand soon and see it on the shelves by the end of 2017.
