I've been using avodart for about 5 years and have checkups with my dermatologist about twice a year and there definitely has been improvement, ever so slight, but better than with propecia. I stopped taking avodart last winter for a couple of months or so (just got lazy and too comfortable) and there has been an increase in hair loss. I am now back on my daily regimen and am hoping to gain what I lost. I've had one HT with Dr. Laura Unger in NYC. Had the front 'quarter' of the scalp done.....didn't make as much difference as I thought it would. I do have a consultation scheduled with Dr. Beehner of Saratoga Springs, NY, in June. Will keep you posted.
