So TA was losing his hair young? I would have to look up what percentage of men lose their hair at certain ages. I am grateful that I have not lost a follicle so far, but I'm lucky. I have TONS of white hairs though. Possibly thousands. I don't know what the total hair count is, but I have a lot of white hair. Maybe not quite enough for people to notice - even despite the contrast, my hair is still pretty dark, but I definitely have a massive number of white hairs.
If TA's hair loss stopped progressing at that point, he is still in a pretty good spot.
It blows my mind to think that certain people start losing their hair by the time they are finished puberty. I have known some bodybuilders to lose their hair earlier than they otherwise would have - and then there are men like Gunter Schlierkamp whose hair seemed to be immune to falling out, regardless of bodybuilding hormones he may have used.
