Kerastase Bain Therapiste is designed for hair with an erosion level of 3-4, to help renew limp, lifeless hair and appearance of fibre quality. Kerastase Bain Therapiste has unique jelly-like texture specially formulated with an innovative FIBRA-KAPTM formula to deliver keratin associated proteins (KAPs) to repair hair fibres and the internal architecture for healthy-looking, hydrated hair. This balm-in-shampoo renews split ends and brittle strands by enveloping hair, increasing strength and protecting from further damage. It is a must have for very damaged and over-processed hair.
