Metformin doesn't directly cause hair loss, but it CAN interfere with the absorption of vit. B12 - which can then lead to hair loss.
I would highly suggest getting your B12 levels tested. Your body has about a 3-month supply that it keeps at all times, so the timing would be about right. If your B12 is low, you would get a couple of injections to bring it back up, then take a good supplement (1,000 mcg/day or so)to keep it that way.
Low B12 causes other symptoms, too, like extreme fatigue.
It's worth checking out, anyways. If it is that, it's an easy problem to fix, and pretty inexpensive, too.
Take care, and HTH! (((HUGS)))
