Causes

Head lice infect hair on the head. Tiny eggs on the hair look like flakes of dandruff. However, instead of flaking off the scalp, they stay put. Head lice can live up to 30 days on a human. Their eggs can live for more than 2 weeks. Head lice spread easily, particularly among school children. Head lice are more common in close, overcrowded living conditions.
