Offering innovative acidic care for coloured hair, the Kérastase Chroma Absolu Leave-In Serum promotes shine and vibrancy. Offering daily defence against heat and humidity, the serum works to combat the visible signs of colour damage. Imparting a glossy finish, the lightweight serum helps to protect your coloured hair from the effects of environmental aggressors. The leave-in treatment is enriched with antioxidant vitamin E, helping to reduce colour oxidisation. Lactic acid gently exfoliates and seals the hair’s surface, helping to trap dull minerals while enhancing colour clarity. The serum seeks to extend colour vibrancy, promoting a sleek appearance, ideal for all porous, colour-treated hair types.
