» ketoconazole,
Yes, keto is helpful against hair loss, as I mentioned. But there is no proof that the reason for its effectiveness is because it kills fungus. On the contrary, the effect is generally attributed to its anti-androgen properties.
» reservatrol,
I haven’t heard about it before. I did a cursory search but didn’t find anything to suggest it had been proven to prevent hair loss. It is an anti-inflammatory (in mice at least). So if it actually is effective against hair loss, that could well be the reason.
» half of the topicals the natural guys use,
Can’t comment on that unless you enumerate them. I general, though, that type of anectodal evidence isn’t very credible. Published, peer-reviewed double-blind placebo studies are what really count. Preferably in humans. Naturally there can be other indications that something works, but that can hardly be called “overwhelming evidence”.

You said it: anecdotal. There are a billion factors which could have contributed to his reversal, if he indeed exists, indeed isn’t a mouse, indeed was balding and indeed reversed his hair loss. 
» but piroctone olamine is antibacterial as well,
Is it? As far as I can tell, it is effective against fungal infections, not bacteria (perhaps I’m being anal). Anyway, I can’t find any reliable sources that conclude that it is helpful against hair loss. Obviously, it is even harder to find any sources that conclude that it is helpful against hair loss specifically because it kill bacteria (or fungus). I found a company or two who claim that their product containing PO will give you your hair back. Needless to say, that counts for nothing.
» Roxithromycin is in clinical trials for mpb,
I look forward to seeing the results of that trial. As of yet, I haven’t seen anything. Until then, no conclusions should be made. But it is interesting, so thanks for the heads-up!

The patent is not proof that it works, much less proof that it works against hair loss because it kills fungus or bacteria. Actually, the patent mentions the synthetic steroid hydrocortisone, among other things, which is a fairly powerful anti-inflammatory. Once again, an autoimmune system disorder (i.e. chronic inflammation), could account for its potential success.

I don’t have that much time. If I google for 5 years, the cure will be here anyway…

Possibly. You might very well be right about that.

Not at all! But that doesn’t mean that they actually work against hair loss, let alone by specifically killing fungus/bacteria.

Thanks for the info! I’ll research some more, but this far I haven’t found anything to persuade me that there is conclusive evidence supporting your theory. Don’t get me wrong, it is an interesting thought and naturally it is quite possible you are right anyway.
