Lice are small, wingless, gray-tan insects. Head lice only live on humans, and anyone can get them, even with good health habits and hair washing. Head lice can be spread from one person to another by close contact or by sharing personal items. Lice lay tiny white eggs called nits that may also be seen in the hair.
They do not cause serious illness.
Your child may have one or more of the following symptoms:
