Head lice are tiny bugs that can live in your hair and on your head. Live lice are tan to greyish white. They're about the size of a sesame seed. It may be easiest to find them at the base of the scalp, at the bottom of the neck, and behind the ears. When you have lice, all people living in your home need to be carefully checked and then treated.
Lice eggs (nits) may be easier to see than live lice. They look like tiny yellow or white dots attached to the hair, close to the scalp. Nits can look like dandruff. But you can't pick them off with your fingernail or brush them away.
Lice aren't dangerous. They don't spread disease or have anything to do with how clean someone is. The lice may make your head itch.
Lice won't go away without treatment. You can treat lice and their eggs with prescription or over-the-counter medicines. After treatment, your skin may still itch for a week or more. This is because of your body's reaction to the lice.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
