Head Lice | Overview


What are head lice?

Head lice are small wingless insects (bugs) that can get on your hair and scalp. Lice are parasites (say: “pah-ruh-sytes”), which means that they feed on very small amounts of your blood. Lice bites may cause constant scratching and lead to skin irritation or even infection.
