Natural Remedies for Lice

Lice cures: I am a foster parent, and as yet have never had a new child placed with me that didn't have lice. I have tried many remedies, including the tea tree, and the chemical, but the thing that has consistently worked for me the FIRST time is dyeing the child's hair. I use a commercial dye, and dye it the same color as the hair so it's not a dramatic change. Then, after the dyeing, we comb out the dead bugs and all nits. In two days after coming and combing, I use a salt water gel. This gel is applied, use a shower cap to cover for an hour or so, and then rinse. I then use tea tree oil in their shampoo forever, and we don't ever get them back. It leaves their hair soft and shiny too.
