posted by Dark-Blood

Red hair occurs naturally on approximately 1–2% of the human population.[1] It occurs Mehr frequently (2–6%) in people of northern oder western European ancestry, and less frequently in other populations. Red hair appears in people with two copies of a recessive gene on chromosome 16 which causes a mutation in the MC1R protein.

Red hair varies from a deep burgundy through burnt orange to bright copper. It is characterized Von high levels of the reddish pigment pheomelanin and relatively low levels of the dark pigment eumelanin. The term redhead (originally redd hede) has been in use since at...

Melanoma Medical implications of the red hair gene

posted by Dark-Blood

Melanin in the skin aids UV tolerance through suntanning, but fair-skinned persons lack the levels of melanin needed to prevent UV-induced DNA-damage. Studies have shown that red hair alleles in MC1R increase freckling and decrease tanning ability.[35] It has been found that Europeans who are heterozygous for red hair exhibit increased sensitivity to UV radiation.[36]

Red hair and its relationship to UV sensitivity are of interest to many melanoma researchers. Sunshine can both be good and bad for a person's health and the different alleles on MC1R represent these adaptations. It also has been shown that individuals with pale skin are highly susceptible to a variety of skin cancers such as melanoma, basal cell carcinoma, and squamous cell carcinoma.[37][38]

Pain tolerance and injury

posted by Dark-Blood

Two studies have demonstrated that people with red hair have different sensitivity to pain compared to people with other hair colors. One study found that people with red hair are Mehr sensitive to thermal pain (associated with naturally occurring low vitamin K levels),[39] while another study concluded that redheads are less sensitive to pain from multiple modalities, including noxious stimuli such as electrically induced pain.[40][41][42]

Researchers have found that people with red hair require greater amounts of anesthetic.[43] Other research publications have concluded that women with naturally...

"The Accolade" Von Edmund Blair Leighton
Queen Elizabeth I of England was a redhead, and during the Elizabethan era in England, red hair was fashionable for women. In modern times, red hair is subject to fashion trends; Berühmtheiten such as Nicole Kidman, Alyson Hannigan, Marcia Cross, Christina Hendricks, Emma Stone and Geri Halliwell can boost sales of red hair dye.[citation needed]

Sometimes, red hair darkens as people get older, becoming a Mehr brownish color oder losing some of its vividness. This leads some to associate red hair with youthfulness, a quality that is generally considered desirable....
