Red or titian hair varies from a deep burgundy through burnt orange to bright copper.  People with red hair are sometimes referred to as redheads or gingers (Ruth) and in Australian slang as bluey or blue.Approximately 1% to 2% of the human population has red hair.It occurs more frequently in northern and western Europeans, and their descendants, and at lower frequencies throughout other parts of the world. Red hair appears in people with two copies of a recessive gene on chromosome 16 which causes a mutation in the MC1R protein. It is associated with fair skin color, lighter eye colors (gray,blue, green, and hazel), freckles, and sensitivity to ultraviolet light.

Red hair is the rarest natural hair color in humans. The pale skin associated with red hair may have been advantageous in far-northern climates where sunlight is scarce. Studies by Bodmer and Cavalli-Sforza (1976) hypothesized that lighter skin pigmentation prevents rickets in colder latitudes by encouraging higher levels of Vitamin D production and also allows the individual to retain heat better than someone with darker skin.

A DNA study has concluded that some Neanderthals also had red hair, although the mutation responsible for this differs from that which causes red hair in modern humans…
