Can propecia really work for AGGRESSIVE male pattern baldness?

[jman91]

Ok, so I have been on propecia for roughly 6 months and haven't noticed and continued thinning (i think?) but also have seen no signs of regrowth and my question is that - will propecia work for people who's hair is destined to completely fall out??... i mean, sure I've heard how its halted loads of mens hair loss but is that because they only had mild hair loss? or are there cases of it helping even the most severely predisposed to go chrome dome bald. The reason i'm questioning this drug is because the men in my family didnt just have a bit of gradual receding, they simply lost ALL of their in their ealry 20's so i'm feeling a bit skeptical that this drug is really powerful enough to prevent my fragile little folicules from being killed off.
