Dye that Changes Colour Like a Moodring

"Color-changing hair might seem like something out of a fantasy novel, but Lauren Bowker of The Unseen has made it a reality. Bowker, a chemist and fashion designer, is known for her “high-fashion alchemy.” She’s previously created hue-shifting purses as well as other air sculptures that use science to produce a stunning visual effect. Now, she’s turning her attention towards color-changing hair dye that’s controlled by temperature—when there’s a dramatic spike or drop, the dye seemingly has a mind of its own... Each hue reacts to either bodily or environmental temperatures. Blushing, for instance, causes your body temperature to rise and as a result, a shift in color... Weather is also a factor. With one color combination, stepping into chilly weather shifts blonde hair to a fitting icy blue."
