Resultz® contains isopropyl myristate, a common ingredient in many cosmetic products. Isopropyl myristate dissolves the waxy shell of lice, causing water loss from their body. Once they lose this protective layer, the lice dehydrate, become immobile and die. It’s important that all lice on the infested person’s head are in contact with Resultz® to ensure it will work effectively. Because Resultz® works differently from other commonly used head lice treatments, it may also be an effective treatment in those cases where others have failed.
