KÉRASTASE Nutritive 8H Magic Night Serum — overnight hair serum, hydrating & anti-frizz

If you struggle with dry or frizzy lengths, this lightweight serum works while you sleep to restore moisture and smooth the hair surface. Formulated with niacinamide to help lock in hydration and plant‑based proteins to reinforce hair fibers, the product is designed to absorb overnight without transferring onto pillowcases. Use a small amount on dry or damp hair a few times a week for clearer combing and enhanced shine by morning.

How does this serum hydrate and protect hair overnight?

The formula combines humectant and protein‑rich ingredients that attract and retain moisture while coating the hair shaft to reduce friction. As you sleep, the serum penetrates lengths and ends to soften and detangle without leaving heavy residue.

• Niacinamide helps lock in water for extended hydration.
• Plant‑based proteins supply nutrients to strengthen dry ends.
• Lightweight texture absorbs overnight, minimizing transfer to pillows.

Will it reduce frizz and improve shine by morning?

Yes—its smoothing components tame flyaways and fill the hair surface to reflect light more evenly. After overnight use, hair looks smoother, feels silkier and shows improved luminosity without oiliness.

• Softens cuticle uplift that causes frizz and static.
• Enhances natural shine through surface smoothing.
• Non‑greasy finish keeps hair touchable and light.

How should I apply the serum for best results?

Apply one to two pumps before bed to dry or slightly damp lengths and ends, then distribute evenly with fingers or a wide‑tooth comb. Leave it in overnight; no morning rinse needed. Repeat around three nights per week or as required for dryness.

• Use small doses to avoid buildup—focus on mid‑lengths and ends.
• Massage gently to ensure even coverage and detangling effect.
• Combine with your Nutritive conditioner or mask for deeper care.

Is this serum suitable for my hair type and routine?

The Nutritive 8H Magic Night Serum is formulated for hair prone to dryness but is lightweight enough for various textures. It integrates easily into nighttime routines and pairs well with daytime heat protection and regular conditioning for balanced hair health.

• Recommended for dry, frizzy or brittle lengths and ends.
• Works on straight, wavy, curly and coily hair types.
• Use alongside KÉRASTASE Nutritive products for best outcomes.

Who is this for: Ideal for anyone whose hair loses moisture or becomes tangled and dull between washes—especially those seeking a low‑effort, high‑impact overnight treatment. If you want smoother mornings, easier detangling and boosted shine without heaviness, add KÉRASTASE Nutritive 8H Magic Night Serum to your night care ritual.
