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. Use the Off-Black shade to darken all Intense Chroma ID Bonding Color Masks (except Yellow) for muted tone directions.   Chroma ID Bonding Color Masks are perfect for low commitment colour services, to refresh dull mid-lengths and ends, to increase longevity of Igora Royal and Igora Vibrance colours, to recover vibrancy and to keep optimal hair condition. 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. 100% Colour Flexibility: The customisable mix and tone system provides infinite mixing opportunities, from bold and creative, colour refreshment, to pastel or neutralisation services. All shades can be applied directly. Longevity: Depending on shade selection, development time and hair structure, colour lasts up to 12 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.
