The Role of Vitamins and Minerals in Hair Loss: A Review
Almohanna HM, Ahmed AA, Tsatalis JP, Tosti A
Published in Dermatology and Therapy
Key Findings
Evidence supports correcting documented iron, zinc and vitamin D deficiency, but there is no good evidence that biotin or routine micronutrient supplementation stimulates hair growth in people without deficiency.
Conclusions
Micronutrient supplementation helps only where deficiency exists; blanket supplementation is unsupported.
Limitations
Narrative/systematic hybrid review, few double-blind placebo-controlled trials available.
Supplements Studied
Given the role of vitamins and minerals in the hair cycle and immune defense mechanism, large double-blind placebo-cont[rolled trials are needed]
The role of nutrition and diet in treating hair loss represents a dynamic and growing area of inquiry.
Deficiency of such micronutrients may represent a modifiable risk factor associated with the development, prevention, and treatment of alopecia.
Evidence supports correcting documented iron, zinc and vitamin D deficiency, but there is no good evidence that biotin or routine micronutrient supplementation stimulates hair growth in people without deficiency.
Outcomes Measured
Micronutrients such as vitamins and minerals play an important, but not entirely clear role in normal hair follicle development and immune cell function.
