CLEVELAND, OHIO - Treatment of iron deficiency through diet or supplements may help regrow hair, researchers at the Cleveland Clinic report.
Investigators who reviewed scientific literature published over the past 40 years concluded that iron deficiency may be more closely linked to hair loss than was previously thought.
Doctors at the Cleveland Clinic routinely screen patients with hair loss for iron deficiency. A ferritin test can detect iron deficiency in its early stages. If this early deficiency is treated, patients may be able to regrow hair more effectively, researchers say.
