My sister had head lice once and from what I can remember My mom just had her sit in from of her and picked them out and killed them. It was kind of like how baboons groom each other, lol. I'm not sure if the special shampoos were out then or not but we just vaccumed a lot and my mom kept on combing until it was gone. We had a case of it in my boarding school and all the girls put ''grease'' in there hair to try to keep from getting it.
