As I get older I worry about Hair Loss.  It's also known as alopecia.
I have PCOS and worry about it as well.  I have a lot of hair right now, but it's a worry as I get older also.
Hair loss can really mess with people and actually cause psychological issues.
I know a guy that went bald in his 20s, he had a hard time with it, so I can definitely see the psychological issues.
I don't know whats worse going bald of loosing some hair and getting the horseshoe shape hair. I read male hairless is due to a combination of genetics and messed up hormones.
