I totally understand you about the propecia. I actually bought a year's supply of finasteride, took 1 quarter of 1 pill, reconsidered, threw 'em out, and decided to go on minoxidil. This was a couple of months ago. Not sure about the future but I may never try it again... waiting to see how min works out.
So like you I'd be into adding something else if it would help. On this board "the big three" is often discussed, meaning of course finasteride, min and nizoral. From what I can tell, it should be the big two, min and finasteride, and nizoral should be one of the "strong maybes". I guess the "strongest maybe". Hm
