Etymology
The term "red hair" has its roots in the English language. The word "red" comes from the Old English "rēad", while "hair" comes from the Old English "hǣr".
Genetics
Genetics play a significant role in determining hair color. The gene responsible for red hair is the melanocortin 1 receptor (MC1R), which is located on the 16th chromosome. Individuals with two copies of the MC1R gene, or are homozygous, tend to have red hair, fair skin, and a propensity to freckle.
Distribution
Red hair is most commonly found in Northern and Western Europe, particularly in Scotland, Ireland, and Wales. It is estimated that 1-2% of the human population, or about 75-150 million people, have red hair.
