结论

            
            
While iron deficiency is common after pregnancy and may worsen hair shedding, there is very limited evidence that iron supplementation specifically helps with postpartum hair loss, which typically resolves on its own.

                    Only 2 studies address this specific connection, providing very limited evidence

                    Postpartum hair loss is usually temporary and hormonally driven, often resolving within 6-12 months
