  1. Europe And Red Heads Percentage Ginger MC1R correlates with density of cloud cover and levels of precipitation.. Droplets in cloud cover block Ultra Violet UVB and this in contact with the skin is required to produce Vitamin D3. Red hair allows the band of wavelengths of UVB that penetrates a very dense cloud cover and a very dense drizzle also penetrates red hair to reach the skin on the skull to increase Vitamin D3 production in the body. Thus MC1R Ginger is a biological adaption to the very low ambient Ultra Violet levels on the earths surface of Northern Europe within the Atlantic Climate Zone.
