L'Oreal Professionnel's Scalp Advanced Anti-Dandruff Shampoo was targeted for dandruff-prone scalps. Scalp is skin, but a much more complex one. Sebum oxidation and micro cracks on the scalp surface can create dry or oly dandruff. It’s a vicious cycle and you want out. This lightweight cream gently clarifies and effectively removes dry and oily dandruff, while calming the scalp. From the first applications, the appearance of visible flakes is reduced*. It is enriched with Piroctone Olamine, an antibacterial and antifungal active ingredient suitable for dry and oily skin. This shampoo is made with hair pros and is approved by dermatologists. The end result is up to 100% visible dandruff removed* & up to 72h dandruff protection** after only 1 use.
