The Role of Vitamin D in Non-Scarring Alopecia

The document from December 7, 2017, reviews the connection between vitamin D deficiency and non-scarring alopecia, including alopecia areata, female pattern hair loss, and telogen effluvium. It presents evidence from various studies indicating that patients with these hair loss conditions often have lower serum levels of 25-hydroxyvitamin D compared to healthy individuals. Some studies also suggest that vitamin D supplementation, such as topical application of vitamin D analogues, may promote hair regrowth in alopecia areata patients. However, the findings are not conclusive due to limitations like small sample sizes and seasonal variations in vitamin D levels. The document concludes that more research with larger patient groups and standardized measurement protocols is necessary to confirm the role of vitamin D in these conditions and to establish vitamin D supplementation as a potential therapeutic strategy.
