Strengthening shampoo bath for weakened, fine and oily hair prone to hair loss and breakage. Kérastase Genesis Bain Hydra-Fortifiant shampoo is enriched with effective natural ingredients that reduce visible hair loss by up to 80.9%. The shampoo strengthens the hair roots and protects the hair from mechanical damage. Its delicate gel texture transforms into a rich, dense foam upon contact with water. It effectively yet gently removes excess sebum and impurities from the hair and scalp. After the very first application, hair will feel feather-light, velvety soft, beautifully shiny and, above all, protected against unwanted hair loss.
