Specially developed for fine and thinning hair, Kérastase Densifique Femme is a progressive hair density treatment that thickens and texturises hair in need of a boost. Kérastase's unique formula of hyaluronic acid and vitamins B3, B5 and B6 delivers a shot of nutrients to volumise each strand and encourage healthy growth and continued vitality, while advanced stem cell technology brings the very latest in hair density science to this simple at-home regimen. Unlike other treatments that can weigh down hair, making it appear lank and lifeless, this fortifying treatment leaves hair light and regenerated with bounce and natural-looking volume. Kérastase's non-greasy formula includes Stemoxydine, a thickening molecule, which bonds with the hair shaft and plumps the hair fibre. The treatment can be used in conjunction with the Densifique range of products to help defend hair that's prone to thinning and breakage. Apply the leave-in treatment all over on freshly shampooed and conditioned hair, and style with confidence. The treatment should be used as part of a daily styling routine for best results.
