Too much estrogen can result in hair loss yes but many other things cause that too. The fact it's coincided I'd be thinking you don't need the xtra E. 

PC work slow on that one too. 
Progesterone can also cause problems of its own. So yeh micro dosing at the very least and be sure you actually need it.

Agree with everything said in this thread but could as well be temporary hairloss..its what hormones do when their balance swifts.
