Some AA's are already rising E levels a bit, to an extent, which is benefical for some.
Some don't need estrogen, as their follicles aren't dormant, more-over they are just thin and sparse, but not completely gone.
My hairline is super intact (small temple recession, thinning to NW2), my hair is great in some places, but the top is literally grazed, all hairs are there, just thin...
So I would neet to let them regenerate themselves, like a flower where you forgot to give it some water after a few days or week lol.
I gotta pull away the weed and toxic things to let it sprout lol
It depends on someones scalp-, and all over-condition, to evaluate if AAs can thicken up and/or regrow recent "lost" hair.
