well i'm the same boat you are my friend. i have weak male pattern baldness history in my family as well, the only person who was bald was my grandfather on my mother's side. my grandfather on my father's side passed away with a thick head full of hair as well as a teenage hairline, no 'mature' hairline there. my father is in his late 50's and his hair is still all black with a few grays poppin' in here and there. i just turned 26, noticed thinning in the crown about 5 months ago, freaked out and hopped on propecia. went thru the initial shed which was freaking hell, i remember large clumps of hair in the drain after i would shower on a daily basis, i counted about 200 one day. but now about 4 1/2 months in on propecia and i must say that my hair loss has slowed in a dramatic fashion. no more clumps in the drain, although i still do shed when i shower it's usually about 10 or so and not really a cause for a big concern as it was when i first hopped on propecia. now i'm hoping and keeping my fingers crossed for regrowth in the next few months. i'm on propecia everyday and nizoral 2-3 times a week.
