Hi, i have had polycystic ovaries, started metformin 2 yrs now since then i noticed thinning of hair, the front of my hair was becoming bald , did tests for thyroid and hormones, everything is normal. i eat healthy, diet and exercise and is not overweight, so i stopped the metformin because of the hair loss , How long after stopping metformin would the hair loss stop, if it is the metformin causing the hair loss
