Head lice can make schoolchildren and their parents miserable. In addition to the itching and annoyance they cause, head lice also carry a stigma with them, and can cause embarrassment to children and their parents. Every year, up to 12 million children in the United States between the ages of 3 and 11 suffer from head lice. Americans spend one billion dollars annually to treat head lice infestations and prevent their return.
