I recently read the info sheet that came with my Estradiol patch prescription. Listed under "Some other side effects of this drug", the second side effect listed was "hair loss". I have been seen by a dermatologist and three hair replacement surgeons for FPHL and have had 3 PRP injections, one with a-cell added and the other 2 without. No one has touched on this subject. Can the patch be triggering my hair loss or excessive shedding?
