Kérastase Nutritive 8H Magic Night Serum Review: The Night Cream Your Hair Has Been Waiting For
Kérastase Nutritive 8H Magic Night Serum is, at its best, a night cream for your hair that behaves exactly as you wish your skincare would: quietly transformative while you sleep. In our testing, dry, bleached, and overworked hair softened noticeably after a single use and continued to improve in shine and manageability over the following nights. The texture is light, silky, and mercifully non-greasy, making it as suitable for fine, fragile strands as it is for thick, frizzy lengths—provided you adjust the dosage.
The trade-offs of this level of luxury are clear: a bold, perfumed scent that some will adore and others will find overwhelming, and a price that stings more if your hair needs several pumps each night. It won’t replace a full reparative routine for severely damaged hair, nor will it satisfy those who want fragrance-free minimalism. But if you’re seeking a sensorial, salon-grade ritual that leaves hair feeling softer, smoother, and more polished by morning—with no extra rinse-out step—this serum earns its place on the nightstand.
