How old are you?
I'm 23, at 22 I thought I was going bald, but I sought help. They will help you determine your cause for baldness, in my case it wasn't just MPB, but bad diet and pushing myself too hard in losing weight. They did a bunch of thyroid tests and ruled that out as the cause too. I lost weight the unhealthy way, and I also lost lots of hair. I've seen some hair re-growth after proper diet, biotin and tricomin. I used Rogaine for a while, but it was really doing a number on my skin, so I quit.
More importantly, I'm not losing any more hair now. I don't even notice much hair after showering.
