NUTRITIVE 8H MAGIC NIGHT HAIR SERUM

Wake up to softer, smoother and more manageable hair with Kérastase Nutritive 8H Magic Night Hair Serum, a lightweight overnight treatment created for dry, frizzy and moisture-depleted hair.

This fast-absorbing leave-in serum works for up to 8 hours while you sleep, helping replenish moisture, improve softness and reduce the appearance of frizz without leaving hair feeling heavy or greasy. It also helps detangle and smooth the hair fiber, making morning styling easier.

Formulated with niacinamide and plant-based proteins, the serum helps support weakened, dry strands while improving smoothness, shine and overall manageability. It is suitable for a wide range of hair types—from fine and medium hair needing lightweight nourishment to thicker, coarse hair that requires deeper hydration.

There is no need to rinse in the morning, making it an effortless addition to a nighttime haircare routine.
