Research & Development
Kérastase is the first to benefit from the very best of L'Oréal’s advanced research and its numerous scientists dedicated exclusively to haircare. Kérastase is supported worldwide by L’Oreal advanced research, with 700 scientists (US, Brazil, China, India, Japan), 3,420 staff members from 60 different nations, 612 patents registered in 2010 and more than 1,000 products per year. Kérastase technology is distinguished by a unique formulation charter: prototype formulas with powerful active ingredients, high-tech molecular complexes and sensational textures, science inspired by the quest for beautiful hair.
To ensure targeted effectiveness, product formulation procedures are highly demanding, piloted by a specifically-designed program including in vivo tests on all hair types. The evaluation center in Paris, the only one of its kind, has a panel of 8,000 volunteers and 60 experts and conducts 50,000 evaluations per year. The center’s 12 international testing rooms reflect the demanding standards of all of our hairdressers.
