How to use

Why our stylists rate it
From the Partners Hair team
Kérastase Nutritive 8H Magic Night Serum is an overnight leave-in nourishing serum for dry hair. Part of the Kérastase Nutritive range. Lightweight, no-rinse formula that delivers 8 hours of intense hydration, detangling, and nourishment while you sleep — leaving hair softer, shinier, and frizz-free by morning.

Best for: dry, dehydrated, or frizz-prone hair that needs an extra step between wash days; thirsty lengths and ends that respond to deep nightly conditioning; hair that wakes up tangled or rough; the night-time step in a Nutritive routine paired with Bain Magistral and Masque Magistral, or with Masquintense for thicker hair.
Less suited to: blonde, bleached, or highlighted hair where colour-care recovery is the priority (use Blond Absolu Sérum Cicanuit); damaged hair primarily needing structural repair (use Resistance Sérum Thérapiste); heat-styled hair needing primary heat protection (use Nutritive Nectar Thermique or Resistance Ciment Thermique); thin, fine hair that lacks density (use Kérastase Densifique range).

Key actives:
- Plant-based proteins (Hydrolyzed Wheat Protein + Hydrolyzed Corn Protein + Hydrolyzed Soy Protein) — wheat, corn, and soy whole grains act as a dietary supplement; blended with fatty acids, omega, and vitamins to feed essential nutrients into the fibre
- Niacinamide (Vitamin B3) — locks in nutrition, strengthens the fibre barrier for long-lasting health
- Glycerin — plant-derived humectant; boosts the formula's overall hydrating performance
- Iris Florentina Root Extract — botanical that softens and conditions the hair fibre
- Panthenol (Pro-Vitamin B5) + Ascorbyl Glucoside (Vitamin C) — supplementary moisture and antioxidant protection

Benefits:
- +98% stronger hair instantly (Kérastase instrumental test, after one application)
- 84% less frizz instantly
- +48% more softness
- +40% more radiance
- Protects from pillow friction, restores fibre hydration with deep 8-hour action
- Wake up to smooth, easy-to-style, naturally beautiful hair

How to use: Spread one pump in your hands and distribute to the lengths and ends of dry or damp hair before bedtime. Focus on mid-lengths and ends — avoid the roots. No need to rinse in the morning. Style as usual. Pro tip from Kérastase: braid hair in two sections after applying for soft beach waves by morning.

Format: 90ml leave-in night serum.
