It's amazing how many different views come out on this stuff
I think it's amazing how complex it seems to be. Like my theory about insulin a while back - I came up with it before I understood the effects of things like inflammation, and possible effects of low T / high E.
The insulin theory was based on lifting or lowering SHBG, that by increasing your insulin etc, you were lowering your SHBG and so allowing more testosterone to run free in your system, leading to more hair loss. I think there is truth in this still, but apparently things like insulin and cortisol also effect things like testosterone production in the testes. And the habits that lead to them (such as bad diet and stress), seem to also increase inflammation, including of course inflammation in the scalp.
The two main theories I currently can't work out are a) does low T / high E lead to an increase in DHT (I can't find studies on this). b) Does E upregulate the hair follicles RESPONSE to testosterone/DHT?
I think Brian Simonis was saying this, that if you have too much E, it can upregulate the receptors meaning they react more with testosterone/DHT.
I really don't know, but what I do know is it just seems very interesting that guys with metabolic syndrome and who are older bald faster, and both of these things are associated with low E, and high T. I know there are other factors, but that is why I have such open-mindedness for this theory, despite the fact that testosterone is the obvious precursor to DHT.
Anywho, sorry, a tangent there
