Strengthen your hair with the Klorane Keratin Strength Fortifying Spray with Keratin, Quinine, Caffeine and B Vitamins.Specially developed to treat thinning hair caused by stress, fatigue, nutritional imbalances and post-pregnancy, the vegan hair product takes inspiration from the latest methods of micro-nutrition, a scientifically-proven approach to target deficiencies by providing essential nutrients to the core of the hair fiber.
