What I wanted to say is :
A lot of guys are thinking about taking Anti Androgens like Cyproterone, or Bicalutamide, or even Estradiol. They think it's the best choice.
I say : No.
They just have to nuke DHT level. With Dutasteride.
It's not because you lower your testosterone level that your hair will be saved. I'm sure of that now. Even if you lower your testosterone levels to female ranges. Even women, with female testosterone range, lose their hair. That's what I learnt from trans MTF actually. I'm disappointed, because I really thought it will cure my hair loss ...
If you have a very agressive hair loss, don't take Testosterone blockers, just take Dutasteride at high dose, and it will work. And you won't have boobs. But it may kill your libido like it does with me. (And Cyproterone + Bicalutamide + Low dose Dutasteride = high libido).
