Soin Premier Therapiste is a deep repair conditioner to be applied before shampooing. Designed for very damaged and over-processed hair, it uses the Fibre-Kap™ complex to protect the hair, while regenerating the fibre’s inner structure. By applying it prior to shampooing, hair remains lightweight and is not weighed down by the deep repairing ingredients of the complete Résistance Thérapiste routine. It is ideal for hair that has undergone harsh chemical or mechanical treatments. Hair is reconstructed for healthy-looking toned hair.
