Head louse crawling in hairs on skin. Head lice, such as the human head louse (Pediculus humanus capitus), are wingless insects measuring 2-3 millimetres in length. They live on head hair, laying eggs and sucking blood from the scalp. This causes intense itching, provoking scratching that can lead to scalp inflammation or dermatitis.
