KÉRASTASE Nutritive Hydrating Scalp Serum 90 ml — Fast-Absorbing Niacinamide Treatment for Dry Scalp, Lightweight Non-Greasy

KÉRASTASE Nutritive Hydrating Scalp Serum is a lightweight, fast-absorbing topical treatment designed to hydrate and soothe dry scalps while supporting scalp balance and hair nourishment.

This serum combines niacinamide with plant-derived proteins and vitamins to deliver immediate scalp comfort and ongoing moisture retention without leaving greasiness. Designed for direct application to dry or towel-dried scalp, the formula absorbs quickly and can be incorporated into morning routines or used as part of a targeted scalp-care regimen.

How quickly does the serum relieve dry scalp discomfort?

The formula is created for rapid absorption so you should feel reduced tightness and less irritation soon after application. It provides surface moisture and helps reinforce the scalp’s hydration barrier when used consistently.

• Fast-absorbing texture — no oily residue
• Delivers immediate soothing on contact
• Use daily for continued comfort

What are the key active ingredients and how do they help?

Niacinamide is included to support skin barrier function and moisture retention, while plant-based proteins and vitamins supply nutrients that help hair roots feel healthier. The combination targets scalp hydration and helps maintain balance without heavy silicones.

• Niacinamide — aids moisture locking and scalp comfort
• Plant-based proteins — nourish hair fibers at the roots
• Vitamins — support a revitalized scalp environment

How do I use the KÉRASTASE Hydrating Scalp Serum in my routine?

Apply the serum directly to dry or towel-dried areas of the scalp, concentrating where dryness or tightness is strongest. Four applications per session are suggested; massage gently and leave in — do not rinse — then style as usual.

• Apply to dry or towel-dried scalp only
• Dispense four doses per session for optimal coverage
• Massage in gently and leave on; compatible with daytime styling

Will this serum weigh hair down or leave a greasy finish?

No. The product is formulated to be lightweight and non-greasy so it won’t make hair feel heavy or look oily. It absorbs rapidly to target the scalp while allowing normal styling products to perform as expected.

• Light texture — preserves hair movement
• Non-greasy finish — suits fine and thicker hair types
• Works under styling and heat-protection products

Who is this for: KÉRASTASE Nutritive Hydrating Scalp Serum is suited to anyone experiencing dry or uncomfortable scalp sensations who wants a fast-absorbing, leave-in solution. It’s appropriate for those seeking to add targeted scalp hydration to their hair-care routine, and pairs well with other Nutritive collection products for broader hair and scalp maintenance.
