doctor Rassman, How come there are people who have BPH or even prostate cancer and still have a full head of hair? We know DHT is a cause of an enlarged prostate and prostate cancer, and DHT causes hair loss as well. There are so many people with a full head of hair that get BPH and prostate cancer and then there are bald people who don’t have prostate problems at all. What is the connection there? I am kinda confused. So some people don’t have the genes for hairloss and have the genes for BPH and then DHT does its work?

Let’s make it simple —
Genetics cause male pattern hair loss. If you have the genes for male pattern hair loss, DHT is what ultimately causes the hair loss. If you do not have the genes for male patten hair loss, then you can have all the DHT in the world and you will not have hair loss.
Prostate cancer and benign prostatic hyperplasia (BPH or enlarged prostate) has nothing to do with genetic hair loss.

I think the answer to your question is all around you — they’re shopping at the mall, walking out on the street, sitting at a restaurant… or as you note, take a look at your family! Many men are Norwood class 3 and that is their final hair loss pattern. These men make great hair transplant candidates. Of note, only about 7 to 8% of men in the world are Norwood 6 or 7.
Generally, when doctors assess patients with a Norwood scale, it is meant to categorize your eventual balding pattern. You may not look like a Norwood class 6 right now, but it seems two doctors that have examined you think you are going to eventually be a Norwood 6. This likely means you are not a Norwood 3V, but you have a pattern leading to a class 6.
