There is no miracle product to quickly get rid of lice.   The products merely assist in the treatment process.  The most effective way to get rid of lice is to use a non-toxic, enzyme based, product that assists in combing out and a Terminator comb.  The comb has teeth that are very close together and there are small grooves on each tooth.  Consistent, thorough combing over a 3-4 week period is the only way to kill the life cycle and rid your head of any eggs or bugs that could be left behind.
