I know this doesn’t have anything to do with hair loss, but given the fact that many of us that suffer from male pattern baldness take either one of these drugs, I found these results quite interesting I assumed they would be of consequence on bone density. However there are multiple studies showing that the treatment groups taking dutasteride (or finasteride) have no consequences on bone density, potentially even have been beneficial affects on a man’s BMI.
