Head Lice (Pediculosis)
What are Head Lice?
Head lice are tiny insects that feed on blood from the human scalp and lay their eggs on hair. Head lice are very common, particularly in children. There is no connection between head lice and the length of someone's hair or the cleanliness of the hair, body, or home or school environment.
The medical name for head lice is Pediculosis humanus capitis.
