Kérastase

François Dalle launched Kérastase in Paris during 1964 with a distinct vision: to treat hair as a medical concern rather than a cosmetic accessory. This approach established the brand as a pioneer in professional diagnosis, where stylists assess individual scalp conditions before prescribing specific treatments. The company operates under the L'Oréal Professional Products Division, utilizing the parent group's extensive research capabilities to formulate products that blend clinical efficacy with high-performance ingredients.

Headquartered in Paris, the brand maintains an exclusive distribution network that prioritizes professional salons while also reaching select retail partners like Sephora and Amazon. Its portfolio spans shampoos, conditioners, masks, oils, and serums, all categorized by precise hair types such as Blond Absolu for bleached strands or Densifique for thinning hair. Recent strategic moves include hosting its first professional hair care summit in September 2026, signaling a commitment to deeper education for stylists and expansion into a broader wellness ecosystem.
