Hierro para Pérdida Capilar por Deficiencia de Hierro
A Evidencia Múltiples ensayos clínicos de gran tamaño muestran de forma consistente beneficios significativos.Basado en 73 estudios (4 meta-analyses) con 30,034 participantes en total. Los resultados son variados entre los estudios.
Conclusión
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
