SUBRINA RECEPT anti-dandruff shampoo for oily teenage scalp TEEN ACTION contains 100 % natural active ingredient Propanediol Caprylate with clinically proven efficacy, comparable to previously established anti-dandruf active ingredients. The active ingredient Propanediol Caprylate, with an innovative mode of action, targets the cause of dandruff, the Malassezia fungus, and thus maintains the balance of the micromicrobiome on the scalp. Niacinamide balances excessive sebum secretion, soothes the scalp and promotes new hair growth. The shampoo also contains apple cider vinegar, which calms the activity of sebaceous glands and balances the scalp's pH.
