Kerastase is a French hair care brand owned by the cosmetics group L'Oreal. Founded in 1964 by Francois Dahl. During Dahl's management, L'Oreal acquired a number of cosmetic brands, including Lancome, Biotherm, Garnier and others, but Kerastase remained within L'Oreal. Thanks to financial investments in the development of laboratories, the brand quickly conquered the European market, and then expanded to Japan and America. The main success factor is the high-tech innovative complexes developed by the brand.
