With a nourishing complex, the Kérastase Nutritive 8H Magic Night Serum is designed for all hair types and textures. Repairing stressed and damaged tresses, it treats problems such as dryness, lack of shine, split ends and breakage. It also reduces the risk of future breakage and damage, making strands more resistant to exterior conditions. Tending to your locks while you sleep, this serum is intended for overnight use. During these 8 hours, it penetrates the cuticle and fills in traces of damage. Thanks to its non-greasy structure, it still allows the hair to breathe and leave it voluminous in the morning. There is no need to rinse it out in the morning since it is lightweight and leaves no residue. Replenishing dry hair, this serum contains a blend of five essential vitamins that seal the roots and make the strands silky and smooth. Moreover, the Iris root extract coats the fibre to lock all the nutrients and moisture in, so the fibre is stronger and more elastic. Applied to dry or wet hair, this serum makes the hair shiny and bouncy upon regular use.
