Inspired by occult glamour – a spell cast on somebody to make them see something the spell-caster wishes them to see, T H E U N S E E N have developed the world’s first colour changing hair dye.

The F I R E dye is responsive to you and your environment by changing colour to passing temperature fluctuations. Available in multiple colour ranges from bright red to subtle pastels, launching at London Fashion Week in collaboration with Storm Models.

The application of the dye is currently semi-permanent lasting over a few washes and the brand are currently looking for commercial partners to help take the innovation to market.

Just because you want to color your hair doesn't mean you want the same color all the time. Wouldn't it be nice if it could change with the weather, or whether or not you're inside? You might get your wish. The Unseen has developed a color-changing hair dye, Fire, that reacts to shifts in temperature -- it could be red outside and revert to a more natural color indoors. The carbon-based molecules in the dye alter their light absorption when they're subjected to temperature changes, producing different colors that you can reverse just by heading somewhere new.

Creator Lauren Bowker tells Wired that the dye is safe. It uses "less toxic" materials, such as irritants that are wrapped in polymers to minimize the damage to your hair and scalp. In theory, it shouldn't be any more harmful than the dye you buy at the store.

Fire still needs to be refined and fully assessed for safety before you can buy it. However, this isn't one of those far-off projects that will take many years to reach shelves -- there's already production-oriented testing underway. If everything goes smoothly, you could soon have a hair color evolves from moment to moment, not just whenever you feel up to a dyeing session.
