I've noticed my hair looking really think lately. I've always been kind of worried because pretty much every man in my family deals with male pattern baldness, but I'm only 21, so I was kind of hoping I"d at least have another 10 years. While over-researching for the sake of paranoia I learned that your hair can thin and bald from stress, too (I'm a graduate student who just went through a really bad breakup and a really bad time at work, and have been eating horribly), so I'm wondering if it could be that, something totally fixable with time and effort, or if I should get to work fighting biology.
I don't exactly have the means to just run to a dermatologist off what could just be worrying, so I figured I'd see if anyone here has a better idea of what it might be and what I should do. Attached are pics taken in natural daylight, and one with the flash on.





While I'm here, if I'm gonna worry and grab DHT blocking shampoo and finasteride, will there be any ridiculous side-effects if it's NOT MPD? Will anything happen to me or will I just stay the same?
