I've had no sides and good results, I recently added nizoral to finasteride and minoxidil, so still recovering from shedding in terms of thickness, or at least I hope so. But it was thicker before nizoral and I'm keeping the faith. In the temples and fringe (which was becoming an island) definite improvements and advancement, so hell, even if I stay thin-ish in the middle, I'm happy with the results so far.
Anyway though that's just 1 experience, and you won't get anything conclusive in terms of numbers or stats based on people reactions on this forum, it's a mixed bag, even a poll wouldn't help. The guys who have success with any treatment most likely won't come back on here. Even if I do get the results I'm seeking, I'll probably still come here because I find the Impact forum is pretty interesting, however most guys just smash and grab for the info on whatever treatment they're pursuing, and if it works, they'll never return (until said treatment stops working of course). And who can blame them?
So for the most part you'll get people on here who struggle to get a treatment that works, have given up on it altogether and come here as a comfort with other sufferers, or, for those who actually grow hair, they might make a few posts about the success, maybe, and that's the last you'll see of them. So obviously the last type isn't a regular poster, and for every 1 of those guys there's 5 who stay and are more visible.
