Designed for thinning hair and sensitive scalps, the Kérastase Densifique Femme 30 x 6ml Duo is a 30-day programme that, over time, strives to add body to and maintain the density of thinning hair. With a non-greasy formula including a combination of Stemoxydine and Vitamins B3, B5 and B6; hair thickness and feel is helped, while its density is maintained. The product comes as a month-long treatment that works using advanced stem cell science. The regeneration power of these cells is the magic behind the increase in hair density. Not only that, but the hair feels texturised immediately after application. Improved body and shape will begin to show 10 days later, followed by increased mass 30 days after the initial application. Moreover, with continued use, up to 1,700 new hairs will be revealed in as little as 3 months after you first apply the formula. This leave-in-scalp product should be applied daily to the roots of dry or towel-dried hair. Use it every day for a total of 3 months to get the best results.
