Recently my 2 granddaughters got head lice from school. After using a Rid kit and 3 trips to the doctor they finally told me to use Listerine mouthwash and vinegar.
Using a spray bottle so you don't get it in their eyes, saturate the hair with mouthwash, you can use generic and mint flavored if you want. Cover the head with a shower cap to keep the heat in and leave on overnight or all day until hair dries. Rinse out mouthwash, towel dry, and spray hair with vinegar, cover with shower cap and leave on overnight or all day until hair dries. Shampoo and condition then comb with a nit comb.
This might take a few treatments, but it worked and was much safer than the chemicals you can only use once every 10 days, and it is much cheaper. I know this sounds crazy I thought so too, but it does work.
