Finasteride halts the progression of hair loss, but if you stop taking it, does your hair loss resume at the same pace as before, or does it jump to where you would be without finasteride?

It’s hard to explain but basically if a 20 year old starts fin and quits it at 30, will his hair loss continue as if he were 20 or will it continue as if he had never taken fin?
