Sonuç

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
