Maturing hairline or receding?

[asadpotato]

Hey guys, I've never done this before but I think it's about time I started. I am a 22 year old male who continuously stresses about losing his hair. I find myself looking in the mirror for at least 30 min a day just staring at my hairline. Even if it's not that bad, I always compare it to the way it was. I started noticing thinning when I was 17. My hair not only got thin on the top of my head, but the sides and back as well. Before this happened you couldn't even run your fingers through my hair it was so thick; everyone said I had a jewfro. The temples and the corners of my hairline kept getting thinner until I developed a gap between my middle hairline and sides. Although this has happened, the mid part hasn't receded or thinned really. I've been to two dermatologists, the first one said I had MPD(when I was 18), but the second one said I'm developing a mature hairline.(at 21). So I want to ask you guys what you think. Could this be MPD? Or just a hairline that's maturing.It's real wavy so when I don't pull my hair back you can't tell that it is receding but it is. It also looks like it's recedinin a Johnny Depp pattern. Thanks guys
