Myths vs facts: Ferritin and Haut

Ferritin is an iron-storage protein often linked to skin and hair health. A common myth: 'Low ferritin always causes hair loss.' In reality, iron deficiency can contribute to telogen effluvium, but not everyone with low ferritin loses hair – other factors like stress, hormones, and thyroid play a role. Another myth: 'High ferritin is good for the skin.' Fact: Excess iron (e.g., in hemochromatosis) can cause bronze skin discoloration and organ damage. Also, ferritin is an acute-phase reactant; inflammation can elevate levels without true iron overload. Evidence for direct skin effects is moderate: studies show associations between iron deficiency and pale, dry skin, but causality is not strong. Supplements should only be taken if deficiency is confirmed – without testing, overdosing is risky. Bottom line: Ferritin is a marker, not a cure-all. For skin concerns, see a doctor for a comprehensive workup.
