I am fairly confident that if I didn't get on Propecia 4 years ago, my hair line would be sh*t. I remember running my fingers through my hair before I started taking it and hairs just kept falling out, over and over. I went to the doctor the next day and it has been a love affair this whole time (with the Propecia, not the Doctor b****s). Over the past 4 years, my hair line has continued to thin ever so slightly but still looks great. I am using minoxidil now too. Without the Propecia, I feel my hair line would have progressed much quicker than it has.
