Résistance Soin Premier Thérapiste Pre-Treatment

The first step in renewal. A beautiful beginning for hair in need of rebirth. Kérastase Résistance Soin Premier Thérapiste is an innovative pre-shampoo treatment designed to protect and strengthen the fibre before cleansing. Its unique reverse-care formula coats the hair before washing, minimizing friction, breakage, and moisture loss while restoring suppleness and resilience. With a luxurious cream texture, this treatment cushions and repairs the hair from within — preserving the delicate fibre and preparing it for a gentle cleanse. Enriched with the powerful Fibra-Kap™ Complex and nourishing plant extracts, it brings softness, strength, and renewed vitality to even the most compromised strands. Perfect for hair stressed by frequent colouring or heat — especially common in Canada's dry seasons — this treatment helps restore bounce, shine, and confidence. A Curious stylist favourite.
