Checking for lice frequently is the only way from preventing your children from a full blown lice infestation. We have been helping families get rid of lice for over 16 years. We have seen quick lice removal fads come and go. Lice are very hardy and they reproduce quickly. They become immune to the standard lice products. Our enzyme lice shampoo will break the shell of the louse and make it easier to comb out lice and nits.
