A supercharged serum targeting hair that needs help retaining its youthful state, Kérastase Densifique Serum Jeunesse Potion has been designed for thinning and greying hair to protect melanin function, improving natural pigments and to restore both volume and softness so hair looks healthier and revived. Powered by an Anti-OX Cellular system rich in antioxidants, this advanced serum helps slow down the greying process by protecting the melanin that gives hair its natural colour. Melanin production slows down with age and antioxidants help defend against this loss. The infusion of Stemoxydine supports thinning hair by increasing oxygen levels at the scalp, waking up passive hair follicles and enhancing their regenerative abilities. Hair is given more density and appears more voluminous and healthy. The Ceramides and Texturising Polymer in the serum further help with loss of melanin and make hair appear fuller and more bouncy. Ceramides also encourage hair cuticles to lay flat, restoring natural shine whilst strengthening and smoothing locks. On dry or freshly washed towel-dried hair, massage 2-3 sprays over the scalp and then a further 3-4 sprays over the mid-lengths and ends combing through evenly. Leave in and activate the ingredients with a hairdryer.
