New here, so forgive me if this is a tired topic, but what's up with all the hair loss in the peloton? It seems most of these guys are going bald, and at a fairly young age. I know genetics have much to do with it, ( certainly in my case...) but am I correct in assuming it may have to do with testosterone or some other substance? I've heard that excessive testosterone is a factor in baldness, but is this the same kind of hormone that athletes use to boost performance? I just thought this might be a curious link. I guess losing a full head of hair might be a small price to pay to win a GT.
