Head lice are tiny wingless insects that cannot jump or fly. They survive on the human head by sucking blood from the scalp. Lice are not dangerous, do not carry diseases and are not a sign of poor hygiene. During their life cycle, they also lay eggs in your hair. These eggs are called nits. Head lice are common in overcrowded places, especially in the schools.
