How do athletes maintain their hair transplants? Or do they not?

Does anyone know any athletes they can point to as examples?

I assume they wouldn’t be able to stay on finasteride if they are serious about staying at the top of their game since fin messes with hormones and they couldn’t afford to risk that. But are HT even maintainable without fin? Lebron has obviously had quite a few done and it still doesn’t really look great around the middle of his scalp.

An up and coming fighter in my country just publicly posted about getting one done and who knows, maybe they will jump on fin but I HIGHLY doubt it given that he also needs to maintain a certain weight and stay super sharp with reactions. Really interested to see if in 5 years his hair is still decent enough to cover his head
