NATURAL BROWN ROOT TOUCH UP! We recommend colouring your roots when they reach around 2cm in length. Follow these 3 simple steps for the best results: 1. Mix and apply the colour to your roots, and set a timer for 40 minutes. 2. After 40 minutes, run the remaining product through the lengths and ends of your hair. Then leave to develop for another 10 minutes before rinsing. 3. Follow with our Reincarnation Shampoo and Keep It Sealed Conditioner. #nobleachlondon #permanentdye
