Offering innovative acidic care for coloured hair, the KŽrastase 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 hairÕs surface, helping to trap dulling minerals, while enhancing colour clarity. Promoting a sleek appearance, the serum seeks to extend colour vibrancy, ideal for all porous, colour-treated hair types.
