While hair loss is a common postpartum symptom due to shifting hormones, some parents report increased shedding after switching to a strict dairy-free elimination diet. If you experience extreme hair loss, consult your gynecologist to check your ferritin, iron, B12, and thyroid levels, as these deficiencies can be exacerbated by dietary changes. Focus on nutrition and keep track of your blood work to ensure you are meeting your body's needs while breastfeeding.
