When you try to get rid of lice by yourself you must start with a good lice shampoo. A lot of shampoo's on the market today rely on pesticides to kill the bug. Why would you want to put pesticide on your child's head? Licenders all natural head lice shampoo uses enzymes to kill lice. Enzymes are proteins that speed up the growth of the shell of the bug and cause it to crack and die. We use our shampoo every day in our LICE TREATMENT CENTER and are always amazed with the results.
