Here's some pictures for more reference.
This picture is from 3 years ago, as you can see I've always had this really weird hairline.

The front of my hair has looked exactly the same, even in pictures when I was really young.
Now, here's a picture of the side of my head from around 3 years ago as well.

Now, here are pictures of my hairline today. I've noticed a little bit of thinning/minaturization a that temples, but nothing at the front of the hairline. I'm not sure if this is my hairline maturing or what.

In terms of family history, my dad has great hair at 55. My paternal grandfather had good hair before he passed away, and my maternal grandfather lost his hair in his 70sNow, my hair density is fine. I went to the dermatologist a few months ago and she said my hair was completely fine, even though I'm not completely inclined to believe what she says. I also asked my barber, and he said my hair quality was great. The only thing I've noticed is maybe a tiny bit of thinning on my left temple. Could this be slow male pattern baldness or just a weird mature hairline?
