In November 2011 I had 2000 FUT with great success. I keep reading about shock loss, which I didn't experience with my first treatment, and I don't use Propecia or any other treatment. I have to admit I have fallen behind in the technology since my transplant. I am considering 1500 more FUT to make my hair fuller in a couple years. My fear is messing up a good thing, and experiencing shock loss the 2nd time around. Should I start using Propecia now in preparation, and are the transplants more prone to shock loss than native hair?
