In addition, other genetic and environmental factors can affect hair color in humans for instance, mutations in the melanocortin 1 receptor (MC1R) gene can lead to red or auburn hair, and exposure to ultraviolet radiation can damage hair and alter its pigmentation. ĭifferent hair color phenotypes arise primarily as a result of varying ratios of these two pigments in the human population, although Europeans show the greatest range in pigmentation overall. Inside the melanocytes, tyrosine is converted into L-DOPA and then L-dopaquinone, which in turn is formed into pheomelanin or eumelanin. Two types of pigment give hair its color, black-brown eumelanin and reddish-brown/reddish-yellow pheomelanin, synthesized by melanocytes. identified 13 DNA variations across 11 different genes that could be used to predict hair color.

The tone of the hair is dependent on the ratio of black or brown eumelanin to yellow or red pheomelanin. Generally, if more melanin is present, the color of the hair is darker if less melanin is present, the hair is lighter. Human hair color is the pigmentation of human hair follicles due to two types of melanin: eumelanin and pheomelanin.
