Have you guys tried the mayonnaise treatment? I've read a lot of testimonials that this works! Just coat the hair with mayonnaise then cover with shower cap, then sleep on it. Some let is stand for 4 hours, and will not leave a single louse alive. the challenge comes when you rinse it off. others used dish washing liquid to remove the mayo.
Yes. This is the same as the olive oil. Both suffocate the live lice. The nits still need to be picked/combed out. Dawn dish detergent does wonders for washing it out.
