Provider told me hair loss was due to stress even though late last year and early this year I have been meditating everyday and managing stress better than I ever have. I wasn't listened to and it was hard to listen to the doctor. He didn't communicate well and went on some long tangents that had a lot of filler words. It was hard to talk ask about other factor (nutritional issues, etc) as he was pretty set on it being stress. And he didn't take time to fully understand the questions I was asking. There was no real point in going to this visit other then if I lose half of my hair again I could come get a biopsy.
