Nad Hair Loss Control Shampoo, bought with my own money

I purchased this product for 7 won during a promotional event. I bought five and have been using them well ever since. Since I bought it so cheaply, you might expect me to have some preconceived notions, but I tried my best to use it without being biased and verify its effectiveness. However, I still don't know if it helps with hair loss. My hair is falling out just the same as before. Haha. Will I see results after using it for a few months?
