결론

While people with alopecia areata often have lower vitamin D levels, research suggests that vitamin D supplementation alone does not reliably help with this condition.

  • 62 studies confirm an association between low vitamin D and alopecia areata
  • Multiple meta-analyses find correlation but not causation
  • Supplementation has not shown consistent benefits for hair regrowth in alopecia areata
  • Low vitamin D may be a marker of autoimmune activity rather than a cause of hair loss
