How will I know if I have head lice?
You may have a tickling feeling within your hair, itching, or sores on the scalp from scratching. In good light, another person may be able to see lice moving within your hair or their nits attached to the hair shafts.
What are nits?
Nits are lice eggs. They are oval-shaped and usually a grayish- white, although color can vary. Nits are generally laid close to the scalp, but can be found anywhere on the hair shaft. Dry skin or dandruff is often mistaken for nits; however, dandruff can be easily removed whereas nits are firmly attached to the hair shaft and must be scraped off with a lice comb or fingernails.
How are head lice transmitted?
