Videos of color-changing hair have been floating around the web for a while -- in one, a woman's hair seems to magically change color when she steps into the right light, in another, a woman flips her part and her hair is suddenly pink instead of blue. But those videos are just illusions. This is the real deal.
Meet FIRE: a newly developed hair dye that changes color when the temperature drops or rises, which launched during London Fashion Week in February. FIRE was created by witch/alchemist Lauren Bowker, who works under the brandname THEUNSEEN.
So, how, exactly does this color-changing dye work?
“When heat hits the pigment, or if the cool hits the pigment, it changes the bonds of the chemistry to give you a different color, so it’s like a chemical reaction,” Bowker told Dazed last month. “However, we also work with ones that change their structure, which gives you a light refraction instead, so it’s more like a prism color change. On the outsider’s version of what the technology does, it changes its color to temperatures. So we tuned those so that if you're inside you get one color and if you're outside you get another color. If you have red hair and you’re in the wind it might go blue. So what we did was look at data patterns of weathers and the environment in different countries and tailor the color changes to correlate with those.”
Through her work, Bowker aims to make science more accessible and to explore the things around us we may not be able to see (hence, her brandname). As she explained to Dazed, if she handed someone a book of data which symbolized their carbon footprint, they'd probably just skim over it before tossing it aside.
"But if I give you a jacket, put you behind a bus and that jacket changes color to visibly show you the pollution that surrounds you at that moment, you’re really going to understand it and have more of a connection to it," she said. "The reason I use color a lot as a data visualization in materials that we’re familiar with, is to allow people to see the bigger picture.”
