Finasteride over time

Do you build up tolerance of finasteride/dutasteride over the years, or is it more your follicles have just become more sensitive?
I think that finasteride keeps its effectiveness; however, your genetics is a variable that could increase more hair loss, overwhelming the finasteride. That is tied to your genetics.
