The Kérastase Nutritive 8H Magic Night Serum is a luxurious leave-in overnight treatment designed to deeply nourish and restore dry, brittle hair while you sleep. Enriched with a potent blend of nourishing actives, this lightweight serum penetrates each strand to deliver up to 8 hours of continuous overnight nourishment, leaving hair visibly softer, smoother, and easier to style by morning. It effortlessly detangles knots, reduces frizz, and forms a protective shield around the hair fiber to guard against daily environmental stressors. Simply apply before bed, allow 100% absorption overnight, and wake up to sublimely silky, manageable hair with a weightless, non-greasy finish. Ideal for those with dry or damaged hair seeking a salon-quality treatment in the comfort of their own home.
