Controversies of micronutrients supplementation in hair loss

Abstract

Hair loss is a common problem causing significant psychosocial impact in the affected individuals. Supplementation of micronutrients in various combinations is commonly practiced by dermatologists for hair loss. Even though the micronutrients are essential for hair growth, their exact role in the pathogenesis of hair loss is controversial. Therefore, in the absence of documented deficiency, the role of supplementing these micronutrients is debatable. It may rather lead to toxicities and unintentional medical consequences. Due to inadequate evidence supporting the role of micronutrients in hair loss, further research is recommended to bridge the gaps in our knowledge. This perspective discusses the role and controversies in using various micronutrients in hair loss.
