The Dermatologist's Guide to Beards: A Review of Structure, Function, Care, and Pathology.

Facial hair is a commonly desired feature for many individuals. Despite a breadth of dermatology literature covering strategies for removing facial hair, there are no known articles summarizing strategies for facial hair growth or reviewing common facial hair pathologies. Here, we assess Google Trends to describe significant increases in terms related to facial hair growth and maintenance over the last decade, suggesting an increased public interest on this topic. Next, we review ethnic differences in facial hair growth that may affect facial hair distribution, growth, and predisposition to certain facial hair pathologies. Lastly, we review studies on agents used for facial hair growth and review common facial hair pathologies.
