Getting rid of lice involves a good solid comb (you only ever have to purchase this once) and a natural shampoo. Lice repellant is a good thing to have too, then as soon as there is an outbreak start to spray the kids hair to stop them from being easy targets to the nits. Now I have a good remedy I don't change, I just re-order the same stuff - nits don't stand a chance in our house !
