New Premium TS Shampoo wasn't that great for me...

New Premium TS Shampoo is so famous, isn't it? My hair loss has gotten really bad lately, so I spent a lot of time researching and thinking it over before buying this shampoo. There are so many different types of TS Shampoo that I agonized over which one to get... I've been using this shampoo for about a month now, but it doesn't seem to suit me. I don't feel like my hair loss has improved at all.
