Conflicting info on fin...

[nynex]

So I've decided to do something about my hair loss. I'm 22 and I've seen my hair slowly thin away for the past 4-5 years. I have a high hairline and very thin/wispy hair to begin with so even at a NW2-2.5 its become more noticeable than I'd like it to be.

I want to start taking fin, but I'm curious, could taking it exacerbate my hair loss? I've read some users here claiming that fin only made their hair loss much worse. Is this a possibility? If so, why does it happen and what are the odds it could happen to me?
