The best and most efficient way to get rid of lice is to cut off the kids hair. This may sound cruel, but it works. I have a three year old son and three step-kids part time. This past summer the step kids came and their bio-mom said they had had lice but she she had treated it. Well, it didn't really work, and all four kids had lice real bad. As soon as we found out we took them in the bathroom and cut everyone's hair off, including mine and their father's. (the kids all cried, but I think it helped that the we cut our hair too) Then we used something like RID shampoo and lice combs on their hair and washed all the linens in hot water. We replaced their pillowcases every night for a week and repeated the shampooing and combing every week for three weeks too, even though we never saw any more lice after that first treatment. But really, I think that cutting off the hair is the best solution. And to me, the vanity attatched to our hair is much less important than lice free heads. It's only hair, it'll grow back.
