Heya duuuude
This is one area where my research and knowledge is quite limited, I just kinda know enough to know that healthy, strong T levels (but not excessive) and healthy, low E levels (but not excessively low) seems to be the absolute optimum for a man (including a man with hair loss).
I'll have more of a look into this later (I'm spent for now.. lol) but I am with you in pinpointing estrogen as largely a bad thing for men.
Curcumin and Resveratrol is an internal male pattern baldness treatment that has worked on people, and the hormonal shift it triggers increases T, decreases E and slightly decreases 5ar.
I did want to include something in my regimen for reducing estrogen but I'm not really sure it's necessary tbh. Reducing insulin and cortisol, improving my thyroid, ashwagandha, all that kind of stuff should improve my T production, which will in turn reduce E
I believe curcumin also inhibits the "bad" estrogen
