Mine has always been strange. I never had a straight hairline to begin with but I have a fairly small forehead. Now even with the recession the middle looks normal and proportional height but the temples look awful from the front view even though I'm only a NW2.5/NW3. It doesn't really help that one side is noticeably more receded than the other. My biggest issue with hair loss though is that I'm a diffuse thinner as well :sad:
Neil Patrick Harris has a pretty high hairline/big forehead. He'd look weird bald.
I was never a NW1 even as a kid. At best I was a Norwood 1.5. I think there is a connection between a thin/high hairline when you're young and baldness. It's rare you'd see someone who is a Norwood 1 with thick hair go bald at a young age.
