I live in Canada so it takes a very long time to get a dermatologist appointment, I've been going to many family doctors and they're not sure what's going on. Also, I'm pretty sure the white stuff in that picture is just the cotton from the hoodie that got stuck in my hair; however, I do notice...
I am 18 years old and have been losing a lot of hair. The hair at my temples are not receding and there is mainly one spot at the back of my head which is losing a lot of hair (but my hair is very thin overall). I don't know if I am balding or if it is another issue.
