Normally, when activated by a certain hormone, MC1R sparks a series of signals that leads to the production of brown or black pigment. Yet, in cases when both parents are carriers of the recessive MC1R gene and said receptor is mutated or antagonized, it fails to turn hair darker, resulting instead in a beautifully fiery buildup of red pigment.
As previously estimated by BBC News, between one and two percent of the world’s population — or 70 to 140 million people — are redheads. In Scotland and Ireland, around 35 percent of the population carry the recessive gene that yields crimson locks, and the redhead count is around 10 percent. As such, the word ginger often calls to mind visions of Celtic-Germanic attributes — namely, pale, white skin…
White skin and red hair may constitute the stereotypical image of a redhead, but it’s by no means a comprehensive one. French-born, London-based photographer Michelle Marshall is documenting the stunningly diverse manifestations of the MC1R gene, particularly in people of color…
