Kérastase Chronologiste Longevity Potion Age-Defying Scalp Serum brings skincare science to haircare with an advanced overnight treatment designed to target the root causes of hair ageing. As hair and scalp are exposed to daily environmental and mechanical aggressors, visible signs including dryness, dullness, frizz, lack of thickness and volume can become more noticeable. This targeted scalp serum helps revitalise the scalp environment while supporting healthier, denser-looking hair. Powered by 3% Pro-Xylane™ and Ochrophyta Algae, this Kérastase serum provides intensive cellular care while helping strengthen the scalp barrier. Pro-Xylane™ supports the hair root by boosting essential Glycosaminoglycans (GAGs), while Ochrophyta Algae is a biosourced marine active that helps strengthen and protect the scalp barrier. The formula works up to 10 layers deep to help optimise the environment for up to 3 billion scalp cells. Its sophisticated, lightweight texture absorbs easily into the scalp without leaving a greasy residue, making it ideal for overnight wear. Wake up to hair that feels healthier, fuller and smoother, while the luxurious Chronologiste fragrance transforms scalp care into a sensorial nightly ritual.
