Hey everyone. I think I'm having a receding hairline on the temples. I am 20. I noticed that I had a widow's peak when I first shaved my head in May 2010. I have pretty thick hair when I grow it. Neither side of my family is bald but my Father, who is 60, does have a receded hairline but no baldness on top. Both of my brothers, older than me, show no sign of balding.
I know these pictures are not of great quality but I don't have a camera with me and the ones from last year I had to rely on friends' facebook pictures:
What you are showing us in your photos is a normal mature male hairline. The mature male hairline is one of those physical characteristics that differ between males and females. Females normally do not develop this hairline pattern. Males usually do.
