Head lice have bugged people for many centuries. Even though they've been around a long time, many people don't understand what they are or where they come from. Some people think head lice are a sign of a filthy home. Others believe only people who don't wash enough get them. In fact, attracting lice has nothing to do with how clean your home or school is. It's not related to how often you wash or brush your hair. It's not related to your hair length either. Head lice affect people who are rich and people who are poor. They affect people who live in cities and those who live in the country. They affect people all over the world.
