Kerastase Nutri-Supplement Scalp Serum

Dry and itchy scalps have met their match in the Nutri-Supplement Scalp Serum from Parisian hair-care expert Kérastase. The serum is enriched with niacinamide, an ingredient that contains B3: a vital vitamin that your body needs to keep your skin healthy. A non-greasy formula that's easy to apply to the scalp and won't weigh down your hair, it works to hydrate and nourish the youngest cuticles.
