Conclusión

While people with alopecia areata often have lower zinc levels, research is mixed on whether zinc supplementation helps — it may support overall immune health but is not a reliable solution for alopecia areata.

  • Lower zinc levels are consistently found in alopecia areata patients
  • Supplementation studies show inconsistent results for hair regrowth
  • Zinc plays a role in immune function, which is relevant to autoimmune hair loss
  • No large-scale RCT specifically tests zinc supplementation for alopecia areata
