Red Hair

Red hair occurs naturally on approximately 1–2% of the human population. It occurs more frequently (2–6%) in people of northern or western European ancestry, and less frequently in other populations. Red hair appears in people with two copies of a recessive gene on chromosome 16 which causes a mutation in the MC1R protein.

Red hair varies from a deep burgundy through burnt orange to bright copper. It is characterized by high levels of the reddish pigment pheomelanin and relatively low levels of the dark pigment eumelanin. The term redhead (originally redd hede) has been in use since at least 1510. It is associated with fair skin color, lighter eye colors (gray, blue, green, and hazel), freckles, and sensitivity to ultraviolet light.

Cultural reactions have varied from ridicule to admiration; many common stereotypes exist regarding redheads and they are often portrayed as fiery-tempered.

Famous quotes containing the words red and/or hair:

    It might become a wheel spoked red and white
    In alternate stripes converging at a point
    Of flame on the line, with a second wheel below,
    Just rising, accompanying, arranged to cross,
    Through weltering illuminations, humps
    Of billows, downward, toward the drift-fire shore.
    Wallace Stevens (1879–1955)

    West Germans are tall, pert and orthodontically corrected, with hands, teeth and hair as clean as their clothes and clothes as sharp as their looks. Except for the fact that they all speak English pretty well, they’re indistinguishable from Americans.
    —P.J. (Patrick Jake)
