Schwarzkopf Professional introduces ChromaID - the first 100% customisable professional mix and tone system. Schwarzkopf Chroma ID Bonding Color Mask 500ml can easily create any colour required with zero damage and low commitment (direct dye) in all tone directions. Ideal for professional in-salon and at-home hair colour maintenance. These pigmented bonding masks care for hair as they create infinite bold and vibrant colour creations. These pastel and natural shades are intermixable with each other. Or create custom shades by pastelising (mixing) with the Clear Bonding Mask. Use for refreshing in-salon colour services or for quick and easy toning and colour correction in-salon or at home. Made from 100% recycled PET (Bottle and Jar made from polyethylene terephthalate that can be recycled and used to manufacture new bottles and containers). Some available in 250ml. See the rest of the Chroma ID range here How to use Mix the shades of your choice if desired (or use the Clear for a more pastel shade). Always apply the colour evenly to pre-washed and towel-dried hair. Leave for up to 20 minutes for more intensive colour results. Or less if desired (check visually). The colour will last for up to 15 washes but may vary due to the chosen shade, application time and condition of the hair.
