this might be my imagination but I think my shed has gone down significantly while being on Met. Whenever I would comb, a big cluster of hair would come out and now it's just a few strands. I take 500 mgs per day and I've been on it for a couple of weeks. Haven't noticed any weight reduction though. Guess I'll have to wait and see if it really does help my hair. My insulin was on the high end of normal.
