Vitamin D Deficiency and Hair Loss: A Case Report and Review of the Literature for Diagnosis and Treatment

Abstract

A small number of case reports seem to suggest a relationship between vitamin D deficiency and hair thinning. This article takes a look at the link between vitamin D and hair loss and examines the role of vitamin D in hair growth. Although comprehensive research on the direct link between vitamin D deficiency and hair loss in androgenetic alopecia remains incomplete, this article will discuss what we do know so that you can consider supplementation as a potential medical treatment for hair loss in patients where vitamin D deficiency is identified.
