Postpartum hair fall is a very common hormonal occurrence that usually begins to stabilize by the baby's first birthday. If you are experiencing this alongside dandruff, the issue may be exacerbated by water quality. Using a shower filter can help, alongside switching to sulfate-free, gentle shampoos. Ensure your diet is rich in protein and iron, and if the loss feels excessive or you feel physically weak, consult your doctor to check your Vitamin D, B12, and ferritin levels, as these are often the root causes of postpartum hair thinning.
