Oh don't you just hate the lice thing!! When my daughter was younger I spent a small fortune on stuff trying to get rid of the nasty things. I found a shampoo and conditioner at the health food store that you could use everyday unlike the "Rid" and "Nix"and other shampoos that are full of pesticides that you have to wait 10 days between treatments. Now they don't carry it and you have to order online. Fortunately I found my old bottle and looked at the ingredients. I use a shampoo base and conditioner and add tea tree, peppermint, lavender, and eucalyptus essential oils. It works great and as a plus it leaves your hair shiny and you can shampoo eveyday so as the eggs hatch it kills the little buggers.
