Their hair is much more DHT resistant and if they lived long enough they will go bald or they will have very very low DHT.Nonsense. I went completely bald from age 17 to age 22. I was turning into an old man I guess? 20% of men will never lose their hair, not one single hair. Why isn't DHT messing up their hair?!
It's just math and the correct term is correlation. male pattern baldness isn't random, you don't go bald instantly and the pool of 20 years of bald men isn't the same as 50s years old.
