My dd came home fromschool on Weds. with Nits. Treated them with lyclear and combed them through for about an hour. Spoke to her teacherand she went back in Thursday as she had been treated. Thursday washed her hair and put loads of tea-tree oil conditioner and combed through their was a few, tonight same thing but she had more. What can I do it is really freaking me out. Does anyone have any good suggestions to eradicate the evil little things.
