Kérastase Nutritive 8H Magic Night Serum is an overnight leave-in treatment that deeply nourishes and restores dry hair while you sleep. Enriched with a blend of Iris Root extract and a vitamin-rich complex, this lightweight serum penetrates the hair fiber for up to 8 hours of intense hydration and repair.
By morning, hair feels softer, smoother, and more manageable, with long-lasting nourishment and a healthy shine. Its non-greasy texture makes it suitable for all hair types, from fine to thick.
