Am I definitely going bald?

[Scottishlad]

I developed a receding hairline at the age of 16 and thought I would be bald by 20. I am now 24 and my hairline has more or less stayed the same. It may have receded a bit but I can't be sure as I have been covering it up for so long!

Have a look at these photos and tell me what you think. I always thought it was balding but could this be a bad mature hairline? Or maybe my baldness pattern has stalled or is moving really slowly?

I remember crying every time I looked in a mirror when I was in my late teens and thought I was a NW 3 on the scale and that it could never be a mature hairline. Was I right?
