Guys, i just turned 21 years old and, on a random day, somebody took a picture of me when i was looking down and the photo took the top-view of my head. Since then, i'm freaking out because the sides of my hairline appears to be receding (although, my family members said that i always had these receding hairline, as my father and my grandfather had too, and they never became bald). Though, my grandfather from my mother's side is bald, but he's like 70 years old and i don't know since what age he's bald because i don't get any contact with him and neither my mother. I will go to the doctor on 26th october, but since i'm really worried, i would like some opinion about the situation of my hairline... I will leave some photos here of all angles and, based on those, am i becoming bald or is it just a mature hairline?
Thank you very much!
