I think it does if it hasn’t been long since you lost hair, like a few years at most. Even then you’ll regrow hair, like 9 out of 10 men. To the extent it’ll be cosmetically significant? That depends again on amount of years past, aggression of the hair loss, maybe even the amount of estrogen you have. Idk it’s very variable. I’ve heard Asians respond the best, but we should really come together to catalog the results people get.
Like how long have you been using finasteride or dutasteride, what’s your ethnicity, what’s your age, when did you start losing hair and how fast does it progress (also when you started treatment), and finally what type of hair loss is it. Maybe someone should create a google Doctor with all this info.
As for why it happens in some and not others, regrowth of hair follicles needs not only a mechanism to block dht, there needs to be more blood flow into the skin tissue and a reversal of calcification. Estrogen does a lot of that which is why I’m assuming it’s so powerful in regrowing hair. finasteride and dutasteride on the other hand doesn’t do the latter two things to the same extent
