Kerastase Blond Absolu Bain Ultra-Violet 250ml

Bain Ultra-Violet by Kerastase is a hydrating purple shampoo with ultra-violet neutralisers and Vitamins C and E, made to reduce brassiness and increase brightness in lightened, cool blonde or grey hair while locking in plumping hydration from two molecular weights of Hyaluronic Acid.

Its ultra-violet fluid formula neutralises yellow and orange undertones to keep cool blonde bright and hydrated, preserving lasting radiance and protecting against oxidation. Kerastase reports instant neutralisation, 72 hours of brightness and 72 hours of hydration.

Key ingredients: low and high molecular weight Hyaluronic Acid, which improves resistance from within and enhances smoothness on the surface, plus Vitamins C and E to brighten the fibre cuticle and guard against oxidative damage.

How to use: apply to wet hair and leave on for at least two minutes, or longer depending on the degree of neutralisation you want, then rinse thoroughly.
