Forget turning your hair into denim, or a galaxy far, far away, or oil slick or a macaroon parlor, the latest thing is to have a covert rainbow hiding behind your head. "Hidden rainbow hair" is the upgrade on fluorescent locks that makes merely Technicolored hair obsolete.

The trend has taken over London, championed by another salon called Not Another Salon.

It's even cooler in motion.

The vibrant curtain of magic is revealed only when you want it to, making it the new mullet, except good. Business in the front with your natural shade, and a party in the back with the ultimate pop.

It looks super cool when braided.

Another day. Another braid! #hiddenrainbowhair
