Brown hair, also referred to as brunette (when female), is the second-most common human hair color, after black hair. It varies from light to dark brown. It is characterized by moderate levels of the dark pigment eumelanin and no 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, Afghanistan and South Asia where it transitions smoothly into black hair.^[1][2] Additionally, brown hair is common among Australian Aboriginals, East Asians and Melanesians.^[3]

Etymology and grammar

The term brunette is the feminine form of the French word brunet, which is a diminutive form of brun meaning "brown/brown-haired", the feminine of which is brune. All of these terms ultimately derive from the Proto-Indo-European root *bhrūn- "brown, grey". The form "brun" (pronounced /bruːn/) is still commonly used in Scotland, particularly in rural areas, and is also the word for "brown" in the Scandinavian languages. In modern English usage, however, it has lost the diminutive meaning and usually refers to any brown-haired girl or woman, or the associated hair color. Merriam-Webster defines "brunet" as "a person having brown hair"—with which they may have "a relatively dark complexion—spelled brunet when used of a boy or man and usually brunette when used of a girl or woman".^[4] Although brunet is the masculine version of the popular diminutive form used to describe a little boy or young man with brown hair, the use of "brunet" is uncommon in English. One is more likely to say about a man or boy, "He has brown hair" or "He is brown-haired" than to say, "He is a brunette" (or brunet).

Lighter or darker shades of brown hair may be referred to as "light brunette" or "dark brunette", though in such cases one is generally referring only to the hair color, not using the term as a descriptor for the person; one would be unlikely to say, "She is a light brunette." Rather, one would say, "She has light-brown hair."

Black hair

The natural hair color of East Asians is mostly brown to black.^[10] Regarding natural brown hair, Darkest brown and Dark brown to Reddish brown are the most common, and sometimes Darkest brown is mistaken for black. Medium brown hair is also quite frequent, and while light brown hair is less common than medium and dark brown, it's still present to some extent, not rare. Even hair that appears visually black can reveal its color when exposed to light if it contains natural reddish-brown pigment (pheomelanin).^[11] Like Europeans, East Asians' hair color gradually darkens with age, which is why there are more young people with brown hair.^[12]

Biochemistry

The pigment eumelanin gives brown hair its distinctive color. Brown hair has more eumelanin than blond hair but also has far less than black. There are two different types of eumelanin, which are distinguished from each other by their pattern of polymer bonds. The two types are black eumelanin and brown eumelanin. Black eumelanin is the darkest; brown eumelanin is much lighter than black. A small amount of black eumelanin in the absence of other pigments causes grey hair. A small amount of brown eumelanin without any other pigments causes yellow (blond) color hair. Often, natural blond or red hair will darken to a brown color over time. Brown-haired people have medium-thick strands of hair.

Brown-haired people are thought to produce more skin-protecting eumelanin and are associated with having a more even skin tone. The range of skin colors associated with brown hair is vast, ranging from the palest of skin tones to a dark olive complexion.
