Yes, I'm aware that I'm posting quite late and anonymously (I don't have an acount). For future referance- I remember my own lice experiences, and the chemicals are awful. You can use a mixture of shampoo, lemon juice, and olive oil, spread it all over the hair, and then cover it all with plastic wrap for at least half an hour. It sounds weird, but it kills all the lice. Thank god I'm not in elementary school any more.
