head lice
"After the OTC medications did not work on my daughter AT ALL, we finally went to the doctor. He suggested two "no nit-combing" medications, Natroba and Sklice. The reason I didn't take her to the doctor in the first place was because I care very much about the safety of chemicals I put on my little girl's skin, so unapologetically, I put this doc to the test with 101 questions about the two. Fortunately, he seemed very knowledgeable about them both (as he should) and I learned that Natroba is the ONLY prescription out there that is not systemically absorbed in the skin and is safe for mothers who may be pregnant applying the product (which I was at the time) so this was huge to me. I went with Natroba and will never use anything else."
