Will starting metformin increase my hair loss? i have pcos and suffer from male pattern baldness and gradual thinning. i am desperate to find a solution for my hair, which was once very very thick, but also want to lose weight. (i'm 5'4 and 149)

It could: There's nothing in the medical literature about this specifically, but many participants in online forums date the onset of hair loss to the treatment with metformin. It is also not very effective for weight loss, unless you are diabetic. It may well be that you have a progesterone deficiency and that supplementing the progesterone would decrease your hair loss. Ask your doctor to test for this

Male pattern baldnes: Male pattern baldness in a female sounds really odd. I don't know how you got that diagnosis but it sounds to me like you should go see an endocrinologist and bring with you any test results of things that you already have done to you. You live in LA. Go to one of the University Medical Centers and get a good workup.
