What are head lice?
- Head lice are small insects (no larger than a sesame seed when fully grown) with moving legs. They live very close to the scalp.
- Nits are not the same as lice. They are the empty dead egg cases which stick to the hair, and look like specks of dandruff.
- You only have head lice if you find a moving louse (not a nit). Your head does not have to be itchy to have head lice.
