Ideal for dry scalps in need of a nourishment boost, the Kérastase Nutritive Nutri-Supplement Serum hydrates, conditions and softens.

The vitamin-rich treatment harnesses the moisturising properties of niacinamide to help nurture the scalp. Lending a soothing effect, the versatile formula can be used on damp or dry hair, its non-greasy texture sitting comfortably on the scalp.
