How to Check for Lice

Sometimes, it’s difficult to tell if it is lice or just some other scalp condition like dandruff, or even dirt.

Adult lice are usually light brown in color and look like sesame seeds. They often move quickly and can be found on the scalp or hair.

Eggs (nits) are yellow, brown, or tan. They look like tiny seeds and are firmly attached to the hair shaft. They do not move. Click here to learn more about what to look for.
