I am currently using rogaine. I'm not on propecia yet, but I plan on starting soon though. The graft counts I got from the other docs were 1500 and 2000, so I don't really know what they are seeing, but they are all within the 500 grafts from each other. I agree that I might be thinning out in the back too, but I've kind of always had thin hair, so the lighting might be an issue because when I took pictures of my hair from different angles it looked similar. I have three daughters and they all have thin hair too. This might be why I was in denial all these years. Also, I've always had a receding hairline even as a child, so that didn't bother me as much. However, now that I have an island in the frontal area of my hair it's been bothering me quite a bit.
When I shave it bald, I think that I have a decent head for it, but as shallow as it sounds, I've done a lot better with the ladies when I have hair then when I shave it.
