I just found this thread. I'm suffering form hair loss as well, shedding and breaking. It could be my BP meds or my elevated cortisol. I'm currently being tested for Cushings, which is long and involved. My primary Dr won't change my BP meds until I get a diagnosis from my endocrinologist. It so frustrating. I wish I could find a good hairdresser. It took years to find my last one and she left the business 2 yrs ago. I've been cutting my own hair ever since, but haven't needed to cut it at all in the last 6 months.
