hey man, i know what you're talking about with the propecia. unfortunately, i find myself in the small group of men who just can't take it. i tried at both the 1mg and .5 mg levels, and my body just cna't take it. i denied it for a while, but the truth is, between hair and libido, its not even a contest. you should definitely talk to dr. feller. make sure you have no other medical issues that may be the cause. if you're on 1mg a day, he may recommend cutting the dose in half (a lot of doctors do) in order to still retain a lot of teh benefit, while maybe the side effects will subside. the point is, do your research, talk to the doc, and then make the decision that is right for you. if you had a hair transplant, then you and your doctor should have talked about what would happen if you lost more hair, as the TRUTH about propecia is that it will not work forever. Good luck man.
and yes, they will do hair transplants on guys who are not on propecia if they're of a proper age (certainly not before 24-25) and using rogaine. its a cost-benefit thing. if you can be improved even at the risk of shock loss and are willing to accept that you will need more transplants and may not get the coverage you'd hope for, then doctors are willing to give you the chance. once again, propecia does ont work forever, and patients should know that. eventually down the line, you will lose that hair eventually, albeit hopefully not for many years. i'm 23, and have put off having a hair transpalnt becuase i cannot take propecia. this is a choice i've made. its not ideal, but its the hand i've been dealt.
once again, good luck.
