Red hair (or ginger hair) occurs naturally in 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 most commonly in people with two copies of a recessive allele on chromosome 16 which produces an altered version of the MC1R protein.
