That could be baldness there. Not so sure its not Androgenetic Alopecia. The reason I say that, the rest of your
head looks more dense, with hair follicles (top). But that one spot goes about an inch.
Is your hairline where it should be (nostrils => chin = top of nose -> hairline). If it's further than that,
you might want to get it evaluated.
A half inche? As in one centimeter?
You might be a Norwood 1 then. What about the temple points?
One centimeter hairline is a Norwood one, for a guy. Usually it goes North, until it hits the
vertex (North pole).
That doesn't look natural. Sorry to say this, but it's the truth. I would have that looked at.
There's no hair there at the center. Not saying it's Androgenetic Alopecia. But it's probably something.
