baby oil in gel form- saturate the hair and scalp... put a plastic shower cap on her and let it suffocate the nits and live lice over night. The next day there will be dead bugs all inside the rim of the shower cap.... Then Braid the hair very tight and put up in a bun. Leave for the whole next day and then wash out. Then do a med treatment and see if that works... Good Luck!!! I've been working with kids for 14 years and it always works. Another thing is prevention.... Once she is "clean" put listerine in a spray bottle and spray her hair with it... it doesn't smell too bad and it keeps the lice from coming back.
