I think reflex hyperandrogencity is my biggest hurdle to starting finasteride when your hair is still decent. Which is ironic since prevention is key. I’ve researched it a bit but not much has been discussed about it. Only that it’s rare and you’ll notice it if a few months into finasteride you still have more libido, sweating, facial hair, acne, and oiliness.
Another thing I’ve seen discussed is that if you’re losing your hair and your dht levels are low, it implies that a lot of your hair loss is due to androgenic sensitivity, seeing as how even low androgen levels still cause you hair loss. And maybe, just maybe an attribute of this type of sensitivity is a dynamic response to changes in hormonal levels. But again, I really have no clue.
