KÉRASTASE Nutritive Hydrating Scalp Serum for Dry Scalp, 90 ml — Niacinamide, Fast-Absorbing Moisture

KÉRASTASE Nutritive Hydrating Scalp Serum is a fast-absorbing, non-greasy treatment formulated to moisturize and revive dry scalp for immediate comfort and lasting hydration.

This lightweight serum combines niacinamide, plant-based proteins and vitamins to replenish scalp moisture, soothe tightness and support healthier-looking roots. Designed for daily or as-needed use, the formula absorbs quickly without leaving residue, making it easy to add to morning routines or targeted scalp care. Use directly on dry or towel-dried scalp areas, massage gently and leave in—no rinsing required.

How quickly will I feel relief from dryness?

Most users notice immediate hydration and less scalp discomfort after the first applications because the serum is designed to penetrate the scalp surface and lock in moisture. Results build with consistent use, especially when combined with complementary products from the Nutritive range.

• Fast-absorbing lightweight texture for near-instant comfort
• Niacinamide helps retain moisture at the scalp level
• Visible soothing effect after a few applications
• Recommended four doses per session for optimal coverage

How do I apply the serum for best results?

Apply the serum directly to a dry or towel-dried scalp, concentrating on areas that feel most dry or tight. Dispense four doses per treatment, part hair in sections to ensure even coverage, then gently massage—do not rinse—so the active ingredients can act throughout the day.

• Use on dry or towel-dried scalp only
• Part hair in sections to target roots evenly
• Massage briefly to boost absorption
• Leave in; do not rinse for continuous hydration

What are the key ingredients and what do they do?

The serum blends niacinamide with plant-based proteins and vitamins to moisturize the scalp and support hair resilience. Niacinamide helps maintain scalp hydration, while plant proteins deliver nourishing amino acids that help the scalp environment feel healthier and less prone to tightness.

• Niacinamide: helps lock in moisture
• Plant-based proteins: nourish roots and retain hydration
• Vitamins: support overall scalp comfort and vitality
• Light formula: non-greasy and quick to absorb

Can this serum be used with styling products and heat protectants?

Yes—its non-greasy finish makes it compatible with daily styling and heat-protection routines. Apply the serum first to the scalp, allow it to absorb, then style as usual using a heat protectant if you plan to use hot tools.

• Layer under styling products without weighing hair down
• Works well with KÉRASTASE heat protectants and night serums
• Safe for daily use to maintain scalp comfort during styling
• Do not rinse out before applying other treatments

Who is this for: KÉRASTASE Nutritive Hydrating Scalp Serum is aimed at anyone experiencing dry, tight or uncomfortable scalp sensations who wants a lightweight, leave-in solution.
