This advanced dermatological shampoo utilizes NAOS ecobiological principles to permanently clear away persistent, stubborn dandruff. Powered by the exclusive patented DSactiv™ complex, it acts directly on the root biological causes of flaking by reducing Malassezia yeast proliferation and regulating sebum secretion. Formulated with scaling agents like Salicylic Acid, it easily lifts severe flakes while concentrated soothing ingredients immediately calm itching and intense scalp irritation.
