Head Lice are also called nits, kutis, kutu bugs, headlouse or cooties.They are small flat insects, about 2-3 mm long. They live on the scalp (the skin on a person's head where the hair grows from). Head lice lay their eggs (nits) on strands of hair.
Anyone can get head lice- it doesn't matter how clean or dirty a person's hair is. Head Lice spread by crawling from one person's hair to another's - usually between people who are in close contact, such as family or school classmates.
