TLDR A boy with alopecia regrew hair using a vitamin D cream after other treatments failed.
In 2012, a 7-year-old boy with alopecia areata (AA) experienced complete hair regrowth after being treated with topical calcipotriol, a vitamin D analog, once daily for 3 months. Previous treatments, including topical minoxidil and hydrocortisone cream, had been unsuccessful. Hair growth began at 6 weeks, with full regrowth at 3 months, and no relapse occurred in the subsequent 6 months. Post-treatment, there was an increase in vitamin D receptor expression in the hair follicles. This single case indicates that vitamin D analogs could be a viable treatment for AA, particularly when standard treatments fail, but more research is needed to confirm its effectiveness in a larger population.
