To treat head lice at home, special shampoo can be purchasedat most retail stores. Medication can also be obtained from a doctor, according to the Centers for Disease Control.
Apply a medicated shampoo, lotion or cream specially formulated to eradicate head lice to the head as soon as possible after it is confirmed a person has lice, explains KidsHealth. Remove any eggs, called nits, by combing through the hair using a fine-tooth comb.
Head lice are small biting insects that are spread by direct contact. This means that the cause of a head lice infestation is sharing items like hairbrushes that are infested with life, or direct head-to-head contact with an infested person.
Head lice can look like a tiny white speck in a person's hair, or upon closer inspection, they look like a very small light brown six-legged creature roughly the size of a sesame seed. Lice eggs, which are normally close to the scalp, are even smaller and hard to see.
Head lice originate in eggs that female lice lay on the scalps of their hosts, according to Healthline. One female louse lays about four eggs per day and uses sticky material to attach them to the host's hair follicles, making removal difficult.
Men and boys do get head lice; boys are more likely to get lice than men, possibly because head lice dislike testosterone. Women are more likely to get lice than men, possibly because lice are able to climb up their long hair more easily.
Typical symptoms of head lice include an itchy scalp, swollen lymph nodes and pink eye, according to the American Academy of Dermatology. Those with head lice may see crawling bugs on their skin, hair or clothing and find lice eggs, called nits, in their hair.
