First off, I'd like to thank you guys for the support. Like I posted earlier, I was aware of the hair loss, but not the extent of it, particulary up top and in the back...it has taken me by surprise. I'm still a little stunned by it. Just hearing others echo the same comments regarding their "discovery" helps out quite a bit.
Second, I appreciate the up-front comments. My own assessment is that any potential donor hair I have is indeed fine and sparse. I'm thinking there probably isn't enough for a HT to provide me with the type of results I'd be happy with. For me, that means having high density and pretty full coverage (I can live with the high hairline). My limited research and the feedback in this thread is leading me to believe that's not a realistic expectation. I'm not into deluding myself, so at this point I'm seriously considering shaving it off, and if I don't like the result, then trying the Rogaine/Finistride regimen. I dunno, I still have alot of research to do.
Again, thanks for the replies, they are helpful, and feel free to offer any other comments.
