Kérastase Nutri-Supplement Scalp Serum is an intensely nourishing treatment for dry, tight, or uncomfortable scalps. Enriched with niacinamide and plant-based glycerin, this milky leave-in serum hydrates the scalp, soothes dryness, and reinforces the skin barrier. The non-greasy texture absorbs quickly and leaves the scalp feeling balanced, refreshed, and moisturized — ideal for dry hair types needing comfort at the root. Directions: Apply directly to the scalp section by section on towel-dried or dry hair. Use 2–3 pipettes per application. Massage gently with fingertips. Do not rinse. Use regularly for best results.
