Research and promising new treatments for FPHL?!

The more time goes by, the more I am convinced that female pattern hair loss is far more complicated than male AGA, and can be caused by way more things than just DHT.

I've spent a lot of time on the treeless sub, plus researching studies, trials, etc. I know the current understanding of male AGA is that DHT is the cause. So it makes sense that things like finasteride would effectively halt balding in like 80-90% of men. And almost all new trials revolve around reducing/blocking androgens somehow.

However, with us women, it seems only some benefit from anti-androgens (spiro, finasteride, etc). But most of us don't seem to - myself included. I've even seen women on dutasteride with zero DHT in their system still progressingly balding. I'm convinced that while DHT might be the cause for some women, it isn't actually the mechanism for lots of us.... that it's some other hormonal cause.

The treeless sub is great at sharing new insights, theories, studies, etc. so it would be cool to see that type of content for FPHL specifically. Does anyone know if there's any ongoing research specific to FPHL and its unique causes/mechanisms? Any theories on the true cause (besides things like thyroid, iron, etc)?
