I could be wrong, but you probably didn't stay on bicalutamide for long enough (1-2 years to see results). A lady who was balding on 50mg cpa + ethinyl estradiol, and finasteride, but she stopped balding with flutamide 250mg and regrew 21% of her hair.
see study: https://www.fertstert.org/article/S0015-0282(02)04551-X/fulltext
she was a cpa/finasteride non responder like yourself, "Flutamide resulted in a reduction of 21% in Ludwig scores (2.3 ± 0.2 to 1.8 ± 0.1). The other treatment effects were not statistically significant."
the conclusion of the study was that "Flutamide at a dose of 250 mg daily induced a modest improvement in alopecia after 1 year, whereas cyproterone acetate and finasteride were not effective. Treatment for more than 1 year may be required for better results."
this tells us that treatment with AR blockers like flutamine/bicalutamide may take up to 1-2 years to show results.
remember(750mg flutamide=50mg bicalutamide) so 250mg flutamide=16mg bicalutamide and you said you were using up to 200mg bicalutamide. Thats more than 10x the relative dose she was using. Again I could be wrong but Im just trying to give some hope
He has hyperandrogenicity...
Although, I don't think you should use a woman as an example for results. It's a different situation, since women are significantly more sensitive to the effects of androgens. On the other hand, men are significantly more sensitive to the effects of estrogen which could explain why biological men notice faster results.
