This does not say anything about how HRT would work for you. HRT works about the same for everyone, regardless of how well their hair loss has been treated in the past.
Today he is going bald on HRT, and tomorrow HRT has become a cure for him. He is very fickle and I think he is not going bald on HRT. HRT will help 90%+ of people. I started going bald at 16 and all the existing hair loss treatments didn't help me. And HRT is reversing my hair loss.
Whether or not to take HRT is a matter of values and I am not forcing my choice on anyone. But I can't help but notice how much people overestimate the side effects of HRT. It will increase your fat percentage a little, make your skin smoother, cause gynecomastia that can be surgically removed... and that's it. There is nothing mutually exclusive about being a straight guy and taking HRT.
After 4 years, you will need to start getting annual cancer screening. I don't recommend you do this. If God wants to take you to the next world, so be it. Who are you to decide your own destiny, right?
