I treated my daughter with Rid 2 times, then Nix 1 time and still found lice. I took her to the Dr. and used the creme they prescribed. I found lice days after that treatment as well. At my wits end now. I mixed up olive oil and tea tree oil. I saturated her hair with it and put a shower cap on her. I left it for 30 minutes. I then put it on our shampoo and conditioner. The next 2 days she was clear. Then I did find one lice but not any since. It has been 5 days now! No nits no nothing! I will go on TV to advertise this stuff! I do not know why nothing could get rid of these things! I will update if anything changes but right now tea tree oil is my miracle!
