Hair color is the pigmentation of hair follicles due to two types of melanin: eumelanin and pheomelanin. Generally, if more eumelanin is present, the color of the hair is darker; if less eumelanin is present, the hair is lighter. Levels of melanin can vary over time causing a person's hair color to change, and it is possible to have hair follicles of more than one color.
Particular hair colors are associated with ethnic groups. The shades of human hair color are assessed using the Fischer–Saller scale. The Fischer–Saller scale, named after Eugen Fischer and Karl Saller, is used in physical anthropology and medicine to determine the shades of hair color. The scale uses the following designations: A (light blond), B to E (blond), F to L (blond), M to O (dark blond), P to T (brown), U to Y (dark brown/black) and Roman numerals I to IV (red) and V to VI (red blond). See also the Martin–Schultz scale for eye color.
Famous quotes containing the words hair and/or color:
“Now the runaways would run no more and never
again would their hair be tangled into diamonds,
never again their shoes worn down to a laugh,
never the bed falling down into purgatory
to let them climb in after
with their Lucifer kicking.”
—Anne Sexton (19281974)
“Actors work and slaveand it is the color of your hair that can determine your fate in the end.”
