Following exciting social posts featuring rainbow root hairstyles, hidden rainbow hair is the latest multi-hued look to come out of London. Located in the British capital in the heart of Brick Lane, Not Another Salon is "a hair salon for those bored of hair salons" based on the "anti-factory" concept.
They recently shared images of hidden rainbow hair on Instagram. Sort of like an undercut, except instead of a secret haircut, there is a secret and very colorful dye job underneath the top half of the hair. Therefore, if the hair was half up, you would be treated to a vibrant array of ROYGBIV colors. Created by hair stylist and senior colorist Carla, the hairdo will likely spawn multiple copycats.
