Kerastase is a French luxury haircare brand founded in 1964 as a division of L'Oreal, the world's largest beauty company. The brand was conceived as a professional salon-exclusive haircare line combining scientific research with high-end formulations. Kerastase pioneered the concept of prescriptive haircare, where products are recommended based on individual hair and scalp diagnostics performed by trained professionals in salons.
The brand's product portfolio is organized into collections targeting specific hair concerns. Key ranges include Nutritive for dry hair, Resistance for damaged and weakened hair, Discipline for frizz control, Blond Absolu for blonde and highlighted hair, Chronologiste as the brand's prestige anti-aging line, and Genesis for hair prone to falling. Each collection typically includes shampoos, conditioners, masks, serums, and leave-in treatments. Kerastase also offers the Fusio-Dose system, a salon-exclusive customizable treatment that blends concentrated boosters with care formulas for a personalized in-salon experience.
Kerastase positions itself at the premium end of professional haircare, with products generally priced between $30 and $90 for standard items, and higher for specialized treatments and sets. The brand operates through a selective distribution model centered on authorized salons, premium beauty retailers, and its own e-commerce platform. Kerastase maintains a global presence spanning over 60 countries, with particularly strong market positions in Europe, North America, and Asia.
