I was NW4a at age 23. I got on propecia, and it has stopped my hairloss it its tracks for the last 6 years. How can I be so sure? Because I got hair grafts, and to this day there is no recession between the grafts and the original hair. I know where the grafts are because their density is so thin.
Some people told me my hair looked darker after I got on propecia. They did not know I was taking it. They just noticed and told me, with a puzzled look on their face.
I have noticed a difference in the thinning and shedding, I know that people can not predict what my out come will be. I am more interested in knowing if anyone who found dust stopped working after 5+ years tried going back to finasteride, and what the out come was.
