Identify head lice in your hair by looking for adult lice or eggs with a magnifying glass, according to the Centers for Disease Control and Prevention. Live lice are difficult to find and may require a medical professional's help.

Most head lice are likely to be found in the hair around the ears or at the neckline, states the CDC. Adult lice are about the size of a sesame seed and are often tan or grayish-white in color. The immature adults, called nymphs, look like a smaller version of adult lice. Nits, or lice eggs, are difficult to see and can be mistaken for dandruff or hairspray residue. The nits fasten themselves to the hair shaft, usually no more than a quarter-inch from the scalp. Nits can be yellow or white and may be the same color as the hair.

Other than looking for lice, you may have symptoms that point to an infestation, explains the CDC. These symptoms include tickling, or feeling like something is moving on the head, as well as itching, which is caused by an allergic reaction to the lice bites. Head lice are most active at night, and many people with them have trouble sleeping. Some individuals also develop head sores.
