I am a mother of two boys we have had our own issues with head lice. We tried Nix, Rid and everything else under the sun! I was really apprehensive to use anymore of the "over the counter" products (besides the fact that they didn’t work, they have horrific side effects). That’s when I discovered Lice Killer products, this stuff was awesome! We haven’t had a problem since, and now I work here so I get to help people just like you, who feel as helpless as I once did.
