Quick Answer

According to the Center for Disease Control, head lice are spread by head-to-head contact with a person that is already infested.

Sharing clothing is another common method of spreading lice, especially hats, scarves, hair ribbons, barrettes, combs and brushes.

Full Answer

According to the CDC, lice are usually found on the scalp, along the ear line or the back of the neck. However, it is possible for them to be found on eyebrows or eyelashes as well. Symptoms of an infestation include a tickling sensation or the feeling of something moving in one's hair, itching and sores on the head caused by scratching. Diagnosis involves finding a live insect on the scalp. WebMD recommends a special metal-toothed "nit comb" to help search for lice. According to the CDC, lice that are firmly attached to hair about a 1/4 inch away from the scalp strongly suggest an infestation. If they appear higher than that mark, it is likely an old infestation and no longer active. If one is unsure, it is recommended to visit a health care provider. Treatment can be purchased over the counter and is considered safe as long as all directions are followed. WebMD suggests to use the treatment twice, as some lice may be resistant to treatment.
