This serum is specially formulated for oily scalps with dandruff. It contains salicylic acid, zinc PCA and prebiotics that remove excess dead skin cells from the surface of the scalp while calming the itching caused by inflammation. Its synergy of purifying, soothing and antioxidant botanical extracts refreshes the scalp, relieves itching and protects the hair from external aggressions. The scalp is thus clean and healthy. Combined with caffeine, this serum promotes blood circulation in the scalp. Enriched with moisturizing agents, this serum controls excess sebum while protecting the skin's moisture barrier on the scalp.
