Current estimates put that number between one and two percent of the global population. Red hair is caused by a mutation of the melanocortin-1 receptor (MC1R), a type of gene responsible for producing pigment for skin and hair. MC1Rs role in the brain may affect the activity of endorphins one of the bodys natural painkillers. In addition, the particular genetic mutation that leads to red hair may further boost the risk of skin cancer, recent research suggests. In 98% of the population, MC1R produces dark eumelanin, a dark type of pigment. Color psychologists say red provokes arousal more than any other color, and that its an indicator of youth and fertility. Research shows that people with red hair may have more sensitivity to certain types of pain and require 20% more anesthesia.

Alcohol dehydrogenase is a dimeric zinc metalloenzyme that catalyzes the reversible oxidation of alcohols to aldehydes. An MC1R mutation may be involved in pain as well. Research on the relationship between MC1R and red hair has been complicated by the fact that there are other genes that also contribute to the color of hair. The initial National Geographic article actually stated that while redheads may decline, the potential for red isnt going away. For some reason, the idea just stuck rest assured, redheads arent going anywhere. In addition, mutations in the MC1R gene can increase redheads tolerance to alcohol.

In 2005, the University of Louisville discovered this hidden gift and hypothesized that the redhead gene, MC1R, may cause the human temperature-detecting gene to become overactivated, making readheads more sensitive to thermal extremes. Another study out of Oslo University found that redheaded. POMC is cut into different hormones, including one that enhances pain perception (melanocyte stimulating hormone) and another that blocks pain (beta-endorphin).
