Scalp hair loss is a know side effect for some people with Spiro.  It's listed right there in the side effects on drugs.com.

It certainly was for me.  It only took a few days after I stopped using Spiro for significant and mentally depressing  hair loss/shedding to stop. For me hair on my head is VERY important secondary sex characteristic.  Ranking right up there with boobs in importance.

It is quite possible to shed those hairs if you quit progesterone, but why quit progesterone?

I don't think I will because I'm scared of losing hair... I just wanted to cut back on meds. I was thinking after my orchi I'd be on just IV estrogen. That would be ideal for me

My only point being that progesterone, like estrogen, is an active transition hormone. Estrogen and Progesterone work in concert to give you female traits. It's less of a blocker and more of a active role.

I'm not sure that progesterone gives female traits or that it is absolutely essential. I question this, based on my own personal experience and just what I know from this hormone which seems essential for pregnancy, yes but otherwise, not certain.

So far, I'm better without it. YMMV, I guess.
