Kérastase hair care products

Kérastase is a world-renowned luxury hair care brand that was established in 1964 by researchers at L'Oréal Advanced Research. Originally founded in France, the brand was created to bring professional diagnostic care and salon-quality treatments to the high-end consumer market, moving hair care beyond simple cleansing into a specialized ritual.

Today, Kérastase is the crown jewel of L'Oréal's Professional Products Division. While its primary research and manufacturing remain centered in France to maintain its heritage of French excellence, the brand's global reach means products are also manufactured in other advanced facilities in Spain and the United States. It is owned by the L'Oréal Group, the world's largest cosmetics company headquartered in Clichy, France, which continues to drive the brand's innovation in hair science and sustainability.
