Yes, I agree with the bulk of this but remember, it has nothing to do with diet and incipient states of baldness.I think this purely comes down to enzymatic expression of 5a-reductase. I think it's easily possible to highly express 5a-reductase in facial skin while simultaneously expressing enough aromatase expression to support normal growth of facial hair. I think the problem in the balding scalp is due to the fact that there is a high expression of 5AR and very little expression of aromatase. I think it wouldn't be as big a deal if the aromatase expression were higher, but, since it's not, the follicle is starved of the genetic signaling caused by estrogenic activity. Aromatase and 5AR are in competition for substrate (which would be androgens) and when you suddenly cut off the 5AR pathway with an antagonist like finasteride, then the little aromatase enzyme that is present in the balding hair follicle no longer has to compete with 5AR for substrate and the follicle is able to produce sufficient levels of estrogens for normal hair growth. This is why I believe finasteride works. And then it doesn't work shortly thereafter because your body is most certainly going to react to cutting of an entire enzymatic pathway by reducing steroid synthesis, among a variety of other defensive actions it takes like reducing aromatase or estrogen receptor expression. And then that just makes the hair loss problem ultimately worse.
Castration before the age of beard growth generally results in a life-time of child-quality hair. Those who pass that point and who are then castrated, need estrogen to make recoveries but some of them still can struggle with DHT synthesis, so where's it coming from and why is it so persistent? DHT all but refuses to take no for an answer while T plays nicely with others. Being hyper-masculine is almost certainly associated with baldness. But also don't forget. The issue is reaching hair parity with children and females. Many males like Son of Sam have vast amounts of scalp hair and they look like hell.... Much worse than balding men.
