Clear Anti-Dandruff Cream After-Shampoo is a zinc-based conditioner that eliminates dandruff while soothing the scalp. 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.
