When we were looking for a lice shampoo that worked, the criteria was that it had to be safe for children too. There are so many products out there that can cause dangerous side effects. We wanted to stay away from that. We will only market a product that is kid safe. Our shampoo uses peppermint and natural enzymes to keep the bug away. We have used natural lice shampoo for over sixteen years with complete success. When your child has head lice, don't play games, let us get rid of lice for you.
