Am I balding?

[hairquestion]

I'm 17, wondering if corners have always been this high and I've never noticed...is that possible, or is this definitely balding, or mature hairline, or what?

Those pictures are very blurry so it's hard to say with any accuracy. However at your age it's natural for your hairline to mature a bit. If you're just mildly curious about it, I would doubt that you've got any MPB going on. If you're noticing actual changes in the thickness of your hair or movement of the hairline then you may have something going on. But I think the bottom line is that you're likely too young to make any accurate diagnosis.
