After many purchasers from the chemist for treatments that were very expensive, smelt disgusting,and after several treatments the head lice always came back a freind of mine told me about this treatment that she used. Simply buy a cheap conditioner put all over dry hair and scalp and let sit GA_googleFillSlot("minti_advice_island_logged_out_300x250"); for half and hour comb out with a head lice remover comb on to a large piece of paper one you have removed them all rinse out thoroughly. The conditioner smothers them and they die. You will have to keep doing this for a while but it is a lot cheaper then all those expensive treatments on the market and eventually they don't come back. It's easy it doesn't smell a little bit time consuming but worth the result. Also get everyone in the family to do their hair at the same time even if they don't think they have got them. Make sure you clean all your combs and brushes regularly and put boiling water over them.
