Why do some cultures treat different hair colors desirable or undesirable?
Why do we have different hair colors?
Hair color is determined by the amount of a pigment called melanin in hair. An abundance of one type of melanin, called eumelanin, gives people black or brown hair. An abundance of another pigment, called pheomelanin, gives people red hair.
The best-studied hair-color gene in humans is called MC1R (melanocortin 1 receptor), which is involved in the pathway that produces melanin
When the receptor is turned on (activated), it triggers a series of chemical reactions inside melanocytes that stimulate these cells to make eumelanin. If the receptor is not activated or is blocked, melanocytes make pheomelanin instead of eumelanin.
It is estimated that more than 90 percent of people in the world have brown or black hair.
For example, blond-haired children often have darker hair by the time they are teenagers.
Hair color may change over time. Particularly in people of European descent, light hair color may darken as individuals grow older. For example, blond-haired children often have darker hair by the time they are teenagers.
Eumelanins determine how dark or light the hair will be
Everyone has some pheomelanins (reddish) coloring in their hair as well. A person with true red hair will produce a high concentration of pheomelanins.
