For context, last year my hair loss hit rock bottom, it was extremely depressing was steered in the wrong direction and did not improve my hair growth at all.
Estrogen applied topically has helped a lot, although it's not the only piece of the puzzle.
Try to follow some of my recommendations, have some patience and see what happens, and with regard to minoxidil, do not use high dosages of it and definitely do not use a PG containing formula. More is not better with min, you should start low and work your way up. 2% is what I would try max. I would actually prefer doing 1% and applying 2x per day for 3 months to see where I'm at and then increase to 2% if I'm not satisfied and the sides don't manifest.
ah so you applied estriol on scalp as well? Gotta ask you something: does it affect beard growth or hinder it? I know it doesn't got systemic though.
