결론

Iron deficiency is clearly linked to hair loss, and correcting a genuine deficiency may support hair regrowth, but iron supplementation is not universally effective for all types of hair loss.

73 studies across 30,034 participants provide extensive evidence on the iron-hair loss connection
Low serum ferritin levels are frequently observed in patients with hair loss
Supplementation appears most beneficial when a true iron deficiency is documented
Iron supplementation without confirmed deficiency may not improve hair outcomes and can carry risks
