INKWORKS® is a 100% vegan, semi-permanent professional hair colour ideal for adding vibrant hues or subtle pastel tones. It can be used as an overlay for a full-head colour or to create bright flashes on pre-lightened hair. Designed to sit primarily on the outer hair shaft, the intensity of the colour depends on hair porosity and base colour. Your stylist can custom-mix shades from pastel to vibrant reds, greens, and blues using INKWORKS® white. The formula contains conditioning proteins in an acid base, enhancing hair's affinity for colour and resulting in exceptionally shiny, temporary colour.
