After consoling a friend the other night about his receding hairline, I decided to check mine, giving it the first close look I have in my life. I was surprised to find a small bald patch on my lower right temple (My hair's usually 2-4" long, so it's been covered), more like a triangle than anything on the charts, about 1"x1"x1" . I was immeadeatly concerned, as I never thought about male pattern baldness since my dad is in his 60's and has a full head of hair and I never knew my maternal grandfather. Anyways, my left scalp looks perfect, the same as it did when I was 18 (Yes, I consulted photos). So my question is how concerned should I be? I'll be OK with it if I can make it to, say, 40 with moderate recession around the temples (Hamilton IV maybe?), but I'm relatively young (24). Is there any way to gauge how much will be lost? My hair appears to be thin nowhere else, not even in the area surrounding the bare spot, another reason why this was so shocking. Is this unusual? May I have some other problem then typical male pattern baldness?
