I agree here. If Bicalutamide + AR blocker does not help, it means that you have poblems with the backdoor pathway, the adrenal one. Some people, like I and others source their androgens through the adrenal gland, not the gonadal one.
The drug which can help in such cases is Abiraterone Acetate, but I wouldn't recommend that for hair loss or transitioning tbh. Only for life-threatening cases, like actual Prostate Cancer.
Spironolactone, on the other site, helps with the adrenal pathway, as it blocks away Aldosterone, as a SAA.
