    TLDR An elderly man's hair grew back after a treatment that transferred healthy gut bacteria.
    In 2019, a case report detailed an elderly patient with alopecia areata who experienced significant hair regrowth after undergoing a fecal microbiota transplantation (FMT) for a different medical condition. This unexpected outcome led researchers to suggest a potential link between gut microbiota and hair loss. The patient, who had not taken any other therapies for alopecia areata, also reported his white hair turning black. The report also discussed the role of vitamin D and its receptor in hair follicle growth and the prevalence of vitamin D deficiency in patients with alopecia areata. However, the researchers emphasized that further research was needed to confirm these findings and understand the underlying mechanisms.
