Neither vitamin E or biotin supplementation are supported by the literature for treating AGA or TE in addition, biotin supplementation can also lead to dangerous false laboratory results. At the present time there is insufficient data to recommend zinc, riboflavin, folic acid, or vitamin B12 supplementation in cases of deficiency. These iron-deficient patients should also ensure their vitamin C intake is appropriate. If a patient with AGA or TE has low iron levels (more commonly seen in females), supplementation is also recommended. Studies show that supplementing the diet with low levels of vitamin D can improve symptoms of these diseases. While supplementation is relatively affordable and easily accessible, it is important to know which vitamins and minerals are helpful in treating hair loss.Īndrogenetic alopecia (AGA), telogen effluvium (TE) are two common types of hair loss. Vitamins and minerals are important for normal cell growth and function and may contribute to hair loss when they are deficient. Hair loss is a common problem that may be improved with vitamin and mineral supplementation. Plain Language Summary: Plain language summary available for this article. Given the role of vitamins and minerals in the hair cycle and immune defense mechanism, large double-blind placebo-controlled trials are required to determine the effect of specific micronutrient supplementation on hair growth in those with both micronutrient deficiency and non-scarring alopecia to establish any association between hair loss and such micronutrient deficiency. Deficiency of such micronutrients may represent a modifiable risk factor associated with the development, prevention, and treatment of alopecia. ![]() Micronutrients such as vitamins and minerals play an important, but not entirely clear role in normal hair follicle development and immune cell function. ![]() A broad literature search of PubMed and Google Scholar was performed in July 2018 to compile published articles that study the relationship between vitamins and minerals, and hair loss. In this review we summarize the role of vitamins and minerals, such as vitamin A, vitamin B, vitamin C, vitamin D, vitamin E, iron, selenium, and zinc, in non-scarring alopecia. The role of nutrition and diet in treating hair loss represents a dynamic and growing area of inquiry. Management of alopecia is an essential aspect of clinical dermatology given the prevalence of hair loss and its significant impact on patients’ quality of life. Micronutrients are major elements in the normal hair follicle cycle, playing a role in cellular turnover, a frequent occurrence in the matrix cells in the follicle bulb that are rapidly dividing. ![]() There are several reasons to suspect a role for micronutrients in non-scarring alopecia. Answering these queries is frequently challenging, given the enormous and conflicting evidence that exists on this subject. People commonly inquire about vitamin and mineral supplementation and diet as a means to prevent or manage dermatological diseases and, in particular, hair loss.
