Hello , I am 22 years old and unfortunately, my hairline is already a concern . When I was younger I had some vellus hairs on my temples , as well as the front of my hairline . As I’m getting older , the hairs are becoming very thin and my forehead looks much bigger . I also have some weird scalp exposure in the front of my hairline that doesn’t seem to want to grow hair there . I want to make sure I don’t have frontal (hairline) alopecia.
