Clear Anti-Dandruff Shampoo is a silicone-free and sulfate-free shampoo, with antifungal properties, that helps eliminate dandruff. Malassezia is a fungus which is naturally present on the scalp, but its excessive proliferation is often responsible for the appearance of dandruff. This disruption of the scalp appears most often on oily scalps, but appropriate treatments with antifungal actives can purify the scalp and stop the development of this unsightly condition.
