More and more people are looking for alternatives to chemical laden lice treatments. The wisest option is not to use any of these products or treatments because they have very low rates of effectiveness anyway. Instead, you can just wet the hair with some conditioner and comb it through with a good quality metal toothed nit comb.
This method requires plenty of patience but when used regularly, it works well. When you find an infestation do not comb once a week – you need to comb much more frequently than that to ensure that anything that hatches does not have enough time to mature into an adult head louse.
