Head Lice Information Sheet

Head lice are tiny insect parasites that live on the human head, feeding on the scalp several times a day. Head lice reproduce by laying their eggs (nits) on the hair shaft close to the scalp. They are not dangerous, don’t carry diseases and are not a sign of poor hygiene.

Head lice are spread by head-to-head contact with another person who has head lice, e.g. when doing group work at school, playing, or hugging.
