Brown hair is the second most common human hair color, after dark hair. It varies from light brown to almost black hair. This is characterized by high levels of dark pigment eumelanin and lower pheomelanin pigment levels. The strands are thicker than flat hair but not like red hair. People with brown hair are often referred to as brunette, which in French is a feminine form of brunet, a petite of brun (brown, brunette or dark-haired).
Common brown hair is found among the populations of the Western world, especially between Central Europe, Southeastern Europe, Eastern Europe, Southern Europe, Southern Cone, the United States, as well as some populations in the Great Middle East that transition smoothly to black hair. In addition, brown hair is common among Aboriginal Australians and Melanesians. Here we collect some photos for your reference
