Hedrin All in One Shampoo is a specialized and clinically-approved treatment for the management of head lice and their eggs, known as nits. This shampoo is designed to effectively combat head lice infestations in a convenient and easy-to-use formulation.

Head lice (Pediculus humanus capitis) are tiny, wingless insects that live on the human scalp. They feed on blood and lay their eggs on the hair shafts close to the scalp. Head lice are particularly common among children, but anyone can become infested. Infestations are not a result of poor hygiene and can affect anyone.
