Remember in Harry Potter when Nymphadora Tonks changed her hair colour to suit her mood and surroundings? We watched those scenes and secretly wished we too could go from brunette, to blonde, to blue and pink, whenever we fancy.

Alchemist Lauren Bowker at awesome chemist company The Unseen has created a hair dye that changes between colours with temperature. Pretty exciting, ey?
