I think the overall situation of my hair improved from the first time I started medication and then it reached sort of a peak from which it has very slowly being declining, the general quality of my hair is pretty thick, but still the temples are slowly moving backwards (or maybe it will come back, time will tell).
I'm convinced that if I hadn't start on propecia/minoxidil years ago, now my situation would be as that of my older brothers (NW3/4 in their early twenties).
