HRT and hair loss

I used Femhrt for about 3 months and noticed extreme hair loss.  Is this common.  It is listed as a side effect on the package.  Will this hair come back that I have lost.  I stopped the medication over 3 months ago.  Losing my mind over this.

It could be a side effect, however if your hair does not grow back, you could do  a complete hormone workup including TSH, PRL, Testosterone, DHEAS, to get to the cause of the hair loss. Your gynecologist could be consulted or a reproductive endocrinologist. I wish you the best.
