Lice Removal with our enzyme shampoo works by breaking the exoskeleton of the lice. The exoskeleton is the external skeleton that supports the body of the louse. Once this skeleton is broken the lice die and the only remaining lice treatment procedure is to comb out the eggs. Unlike most head lice shampoo's which rely on pesticides which are harmful to your child, Licenders shampoo contains only all natural ingredients. Treat your child's head lice infestation with confidence, call 1-888-LICENDERS.
