I'm pre-T but I've considered it quite a bit. I don't know much about my father's side of the family; on the other hand, pretty much all of the men on my mother's side are bald or have really thin hair. From what I've seen, I'm going to be losing the hair on my head but growing a forest everywhere else. It's a concern, but the benefits outweigh the risks. I wear a hat all the time, anyway.
