What is head lice?

Head lice are parasitic insects that can be found on people’s heads, eyebrows, and eyelashes, according to the Centers for Disease Control and Prevention (CDC). Head lice live by feeding on human blood.

They live close to the scalp so they can eat multiple times a day. Though the thought of lice can be unsettling, they are not known to spread diseases, according to the CDC.

It is estimated that 6 million to 12 million cases of head lice among children ages 3 to 11 happen every year in the U.S., according to the CDC.
