Kérastase Bain Après-Soleil is an after-sun hair bath created to repair coloured hair exposed to the sun. It eliminates build-up of protection products, sand and salt from the scalp and hair, leaving long-lasting softness, suppleness and radiance. Bain Après-Soleil is formulated with Kérastase’s Photo-Défense Filter which provides active protection against both UVA and UVB rays; cationic silicone to create a hydrophobic barrier; ceramide to strengthen and reinforce the hair; and softening and smoothing polymers, for easy detangling.
