Kérastase Resistance ThÉrapiste is a repairing regime for very damaged and over processed hair that is dry and brittle with visible split ends. Enriched with FIBRA-KAP, a powerful complex designed to compensate for missing KAPS (Keratin Associated Proteins). KAPS account for up to 50-60% of the hairs structure and start to deplete when hair becomes damaged. Also formulated with Ressurection Sap, an extract from the Myrothamnus Flabellifolia plant, known for its ability to resurrect itself, helps preserve the structure of the hair fibre. Kérastase Bain ThÉrapiste is a shampoo with a unique jellified texture that repairs and renews the hairs fibre by enveloping them and reducing friction for revitalised shiny hair. Directions for use: Apply a small amount to damp hair and emulsify. Rinse thoroughly. For best results, use as part of the ThÉrapiste routine.
