Head lice are small parasites (Pediculus humanus capitis) that can infest the hair and scalp of humans. Head lice are common in young children and their families.
Head lice may produce intense itching of the scalp, but it often produces no symptoms at all. Other possible signs and symptoms of a head lice infestation include
- a tickling feeling from hair movement,
- nits (lice eggs) stuck on hair shafts, or
- red bumps on the shoulder, neck, and scalp.
Cause of a head lice infestation
