Hey guys, I'm 21 years old am worried that im going bald. I've always had a big forehead and a pretty shit hairline, but I'm starting to worry that im in the early stages of balding. I've read that at this age my hairline could be maturing, but this seems like much more than maturing. I'll post some pictures down below. Adivce very much needed thank you!
