Male Baldness Info

I am 21. I’ve been losing my hair since 17, and it recently just became noticeable (previously I had lush Marc Bolan hair…took a while to see through). I have undertaken a regimen of treatments since November 2007 which is comprised of the following:
Propecia (1X)
Rogaine Foam (2X applications)
Saw Palmetto (supplement, 400 mg each; 2X)
Nioxin 3-part System (no.2; in the shower)
Neutrogena T-Gel (1X; shower)
Nizoral (1x; shower)
I have yet to see any results besides some vellus hairs on my hairline.
I want to know what you think of this lineup of treatments, and if you have any advice regarding what I should do. I have been heartbroken by the loss of my good looks (as I am still young, and all of my friends still look youthful and handsome). Any advice would be appreciated. Thank you.

Hi, I’d really be interested to know if there are any males out there with baldness that have taken vitamins or natural supplements for hair loss? For example, biotin, inositol, B-complex, Hairtopia, anbd Hair Formula 37 are a few natural supplements out there that claim to regrow hair. Personal reviews seem to show that these make hair thicker, shinier, and faster-growing. I’m wondering if they have helped anyone with MPB? Any successes? Any dissapointments? Any feedback would be great, thanks!
