Brown hair, also referred to as brunette (when female) or brunet (when male), is the second-most common human hair color, after black hair. It varies from light brown to dark hair. It is characterized by higher levels of the dark pigment eumelanin and lower levels of the pale pigment pheomelanin.

Brown hair is common among populations in the Western world, especially among those from Northwestern Europe and the United States, as well as populations in Central Europe, Southeastern Europe, Eastern Europe, Southern Europe, Southern Cone, Brazil, Colombia, Costa Rica, Puerto Rico, and also some populations in the Middle East, Central Asia where it transitions smoothly into black hair.[1][2] Additionally, brown hair is common among Australian Aboriginals and Melanesians.[3]
