i also have experienced much hair loss. it has been about 2 years now after the death of my mom, thought it may be just stress or perimenopause (41) but now after doing some research online I do think that it did all began after starting the Wellbutrin xl. I take 300 mg but i am going to talk to my DR. about going off it and maybe taking something else. I also take Effexor too, to help with my depression. any suggestions would be very much appreciated.
