I have head lice. Yes, I know it's gross but I'm not asking you if you think it is or not so don't answer with something like "ewww headlice" or "You wouldn't have that if you weren't so dirty!". Honestly, lice dont like dirty people so thats NOT why I have it. Lice like clean scalps so that they can feed. I know that. I have a very mild case, barely anything. I have dont Rid and Nix three bottles each two treatments per a bottle. It's not working for me. I believe the lice are immune to the chemicals. So, just out of curiousity, would mayo cure my very mild case of head lice?
