Over the summer we had a problem with two children having lice on the property. Since our kids played with them, we other moms took care of the lice issue immediately when we found out, but the parents of the original two let theirs go on so long that the rest of us refused to allow our children to play with theirs. The second time we had a lice issue was with the young girl I babysit. She got them from cheerleading practice. I found them, used Licefree! immediately on both her and my own child and treated the house. What I found after checking my daughter’s hair (she has waist length hair) was that she did not get them this time. The only thing that I can think of was that we had started using tee trea oil in our shampoo for itchy scalp a few weeks prior. I think it really made a difference as my daughter is still lice free.
