Lice are small flat-bodied sucking parasites that live on or near humans or animals. There are three different types of lice:
* head,
* body, or
* pubic lice.

Head lice are the most common type. They feed on the scalp and lay their eggs, called nits, at the base of a strand of hair. The nits look like small gray ovals and are easiest to see behind the ears and at the back of the neck. Body lice actually live in the seams of clothing and not on the skin at all. Pubic lice live in the hair around the sex organs and lay their eggs on shafts of hair. Pubic lice can also live in beards and eyebrows.

The main symptom of lice is severe itching. The skin may also become red and inflamed. The itching and irritation is caused by the saliva from the lice bites. Head and body lice are spread by contact with an infected person or by sharing combs, towels, blankets or clothing. Pubic lice are usually spread by sexual contact.

Head and pubic lice can be easily treated with medicated shampoos or lotions. Because the nits can be hard to remove, it is usually necessary to use a comb with very fine teeth to comb them out of the hair. Often it takes more than one application of the medicated shampoo or lotion to completely get rid of the lice. Treatments can be spaced a week apart to ensure killing all of the nits. Body lice can be removed from clothing or linens simply by washing them. Rugs and carpets can be vacuumed to get rid of lice living in the fibers.

Shampoos or lotions to treat lice can be purchased over the counter at your pharmacy. Follow the instructions carefully. Do not use on infants. If you need advice on specific products or how to use them, ask your pharmacist.
