Hair specialist doctors: Is this simply due to male pattern baldness?

[zero_confidence_balder]

I had a nearly full head of hair last august 2009 (there was a bit of thinning near the crown and that's about it) and by mid-winter 2010, my hair was at this stage (I was under intense stress during that time).

I've been taking propecia and using rogaine every night for 8 months but haven't seen any regrowth. Sure, fine, my hair stopped falling out, but its current state is still far from acceptable. I look at this picture and want to off myself. This is one week after having buzzed it all off with a #2 buzzer. The top of my head looks like that of a 60yo man but I'm 23!!!!! And I used to be incredibly good-looking!

EDIT: I've attached another pic of my head/hair from the summer of 2009 (before operation superfast hairloss began)

I guess I'm hoping for some doc to tell me that I actually have a systemic medical problem that can be easily fixed and all my hair will grow back within weeks...

P.S. I've seen 2 dermatologists. Neither asked me any questions about how fast it happened, etc. They took a quick peek at my head, prescribed me propecia and sent me on my way.
