Like "I just know that Metformin is the culprit. Stress is part of it but I never had this thinning of hair when I was not on it or even when I took , on my own, 1 pill a day. He wasn't happy knowing I was doing one a day. Let me warn you that in time you may get to the point where you are like others and myself where you are too thin and I am almost getting ready to buy a wig if much more goes on the top of my head. It is spreading all directions. Just watch it closely. Once it started it went slowly I guess but it has picked up. I didn't even know I had a bald spot on my head and found out in a terrible way. The little fuzzy white hair isn't trying to grow but in a creeping mode, lol. Good luck to you !!!"
