TAKE-HOME MESSAGE

  • This review article investigates biotin’s impact on hair growth and quality while also appraising the public perception of biotin. No clinical trials supporting the use of biotin for alopecia or to improve hair quantity or quality were found. A notable study found effects on coat quality in dogs treated with biotin, with 60% of dogs with poor coat quality experiencing complete resolution; however, this finding has not been replicated in humans. Molecular-level studies have not shown evidence for improvement on hair development or growth.
  • Little evidence exists that supports a growing public perception that biotin supplementation increases hair growth and quality.

Abstract

Biotin, also known as Vitamin B7 or vitamin H, is a water-soluble B vitamin that acts as an essential cofactor for several carboxylases involved in the cellular metabolism of fatty acids, amino acids, and gluconeogenesis. Although there exists an incredible amount of social media hype and market advertising touting its efficacy for the improvement of hair quantity and quality, biotin’s efficacy for hair remains largely unsubstantiated in scientific literature. We reviewed all pertinent scientific literature regarding the efficacy of biotin supplementation for hair growth and quality improvement, and we also investigated its popularity in society defined as a function of market analytics. To date, there have been no clinical trials conducted to investigate the efficacy of biotin supplementation for the treatment of alopecia of any kind, nor has there been any randomized controlled trial to study its effect on hair quality and quantity in human subjects. Because of the lack of clinical evidence, its use to improve hair quantity or quality is not routinely recommended. However, societal infatuation with biotin supplementation is not only propagated by its glamorization in popular media, its popularity is vastly disproportionate to the insufficient clinical evidence supporting its efficacy in hair improvement. In other words, biotin supplements are quite “in vogue,” without there being any real reason to be so.
