Lice: Removing Nits From Hair

Topic Overview

Lice eggs stick to the hair and can be hard to remove. It is possible that if some eggs survive treatment and are not removed from the hair, they may persist.

The recommended way to treat lice is to use over-the-counter medicated creams, lotions, or shampoos that kill lice. After using medicine to treat lice, some people use a fine-toothed comb to remove head lice and their eggs. A flea comb that's made for dogs and cats will also work. This is called wet combing.

To remove eggs and lice, wet your hair and add conditioner, vinegar, or olive oil. Then comb your hair with a fine-toothed comb. Comb for at least 15 minutes (until you find no more lice or eggs).

If two treatments of medicine do not kill the lice, you can try wet combing every few days. This process can take a lot of time, and you must make sure to get every louse and all eggs. Stop 2 to 3 weeks after the last session in which you found an adult louse.
