Schwarzkopf Chroma ID is a semi-permanent mix and tone colour system with integrated bonding technology. From subtle to bold shades, for 100% colour flexibility without damage.  Chroma ID Color Masks are perfect for low commitment colour services. Offering ultimate colour flexibility, use the Intense Bonding Color Masks alone for bold and expressive colour results, or mix with Bonding Color Masks for shade customisation, or dilute with Clear Bonding Mask for all pastel gradings. Colour & Care in 1 Step: Combining high performing colour with intense care: the treatment based colour allows for simple, quick and perfectly even colour distribution while the integrated bonding technology deeply conditions the hair from within. Direct Useage: All shades can be applied directly: no pre-mixing necessary, for minimum time investment and maximum efficiency! Longevity: Depending on shade selection, development time and hair structure, colour lasts up to 15 washes. Technology: The low salt technology leads to maximum pigment availability in the hair for enhanced colour results while the integrated bonding technology enforces structural bonds in the hair shaft for increased hair strength.
