Metformin itself is not commonly listed as a direct cause of hair loss in people with PCOS. However, hair loss with PCOS is often driven by elevated androgen (male hormone) levels, insulin resistance, and other factors that Metformin is actually prescribed to help manage.
That said, there are a few indirect connections worth knowing about:
- Metformin can sometimes affect nutrient absorption, particularly vitamin B12, and nutritional deficiencies can contribute to hair thinning
- Stress and hormonal fluctuations during treatment changes can also temporarily trigger hair loss
- Some myPCOSteam members have reported changes in hair while on Metformin, though others have seen improvements in PCOS symptoms overall If hair thinning is a concern, it's worth asking a doctor to check iron, vitamin D, and B12 levels, as deficiencies in these can play a role. A doctor can help figure out whether hair loss is related to PCOS hormones, a nutritional gap, or something else entirely — and tailor a treatment plan from there.
