This hair dye is the brainchild of the European firm called The Unseen. Debuted during London Fashion Week, the dye, called "Fire," can change colors depending on the temperature!
The dyes give you two colors
The dye uses thermochromic ink, modified so that it's safe for contact with the skin.
“Magic is only science that we don’t understand yet,” Lauren Bowker, founder of The Unseen
While the allure of color-changing hair is obvious, Bowker says that the real hope is that it will encourage young women to get involved with STEM (Science, Technology, Engineering, Mathematics).
“I really believe it's a great example of a product that celebrates women in science and to encourage young females to see the opportunity for creativity within science and engineering - bringing sci-fi to real life!”
