Much depends on how dire the situation is. I have no dead follicles, all follicles are alive, but there are problems with the quality of the hair. I do not think that in such cases high doses of E are required, I will focus on 300 pg mlMy gut feeling is that low-dose HRT might work to maintain hair but to actually awaken dormant follicles, you might need to "trick" the body's systems into regarding you as XX. At this point, the body sends the appropriate resources to repair the dormant follicles and "to turn them on" again. There's really no need for males to expend resources which are endogenous on hair restoration. For females, hair is actually essential to children's safety as they grab their mother's tresses for balance and safety before walking.
I will try to do without surgery and use Tamoxifen. It raises T and is bad for the hair, but when using E it shouldn't play a big role. It seems to only block estrogen in the breasts. I hope so.
My breasts are not sensitive to estrogen, they don't care about using Bicalutamide, so I think I can handle HRT with tamoxifen. I would take Raloxifene, but it is not in Russia
