for the past 3 - 4 weeks I have been using letro to combat some mild gyno but I have noticed that my hair has become dryer and somewhat thinner/wispier in this time (I have no balding or recession but just overall thinning and dryness of hair).. I googled arimidex and letro and discovered that some side effects of these drugs are in fact hair thinning... has anyone else experienced this?
