Scalp Lice Overview

Another name for Scalp Lice is Head Lice.

What are head lice?
A person with head lice has tiny insects living on the scalp. Lice feed on blood: they must bite the scalp in order to access the blood from the scalp. The bites cause scalp irritation and itching. Lice have a life span of 1 month and reproduce rapidly. Lice eggs are called nits. The insect spreads from person to person by contact with combs, clothes, hats and linens.

What are the symptoms of head lice?
Symptoms of head lice include a scalp rash and scalp itching. Tiny, hard, white eggs may be visible, attached to the hair shafts.

How does the doctor treat head lice?
Treatment for head lice includes washing clothes and bedding in hot water every day. A nit comb helps remove dead eggs from the hair shafts. Additional treatment may include insecticide shampoo or cream, and oral insecticide medications.
