Vitamin D
A 2019 review found evidence to suggest a link between vitamin D deficiency and alopecia areata, which can involve severe hair loss. According to the review, some research also suggests that symptoms of alopecia areata may be more severe in people with low levels of vitamin D. However, the authors of a 2016 study that collected information from 55,929 women in the United States did not find a strong link between total vitamin D intake and hair loss in alopecia areata. Some studies have found that low vitamin D levels may be associated with female pattern hair loss, which is the most common type of hair loss in women.
