Without question, the countries of Ireland and Scotland have the highest percentage of people with naturally red hair. However, precisely what those percentages are and which country's percentage is ultimately the highest is a bit less clear. People with red hair are treated differently in many cultures.
Ireland has the highest number of red-haired people per capita in the world, with the percentage of those with red hair at around 10%.
And the statistics bear that stereotype out. Ireland has the highest per capita percentage of redheads in the world -- anywhere from 10 to 30 percent, according to Eupedia, a website that explores European genetics and ancestry. They are almost equally prevalent in Scotland and other pockets of Celtic pride.
Contrary to what many people assume, redheads did not originate in Scandinavia, Scotland or Ireland, but in central Asia. Their coloring is due to a mutation in the MC1R gene that fails to produce sun-protective, skin-darkening eumelanin and instead causes pale skin, freckles and red hair.
The percentage of redheads in Ireland hovers around the 10% mark. Scotland weighs in at around 6%, followed by England at around 4%. Scottish people may disagree, but we say Ireland is the undisputed world capital of redheads.
Yes, Vikings did have red beards. According to sources, red hair and beards are a genetic trait that is specific to Nordic tribes. It's even thought that some Norsemen would dye their red hair and beards to look blond using lye soap.
Red hair, a Celto-Germanic trait? Red hair has long been associated with Celtic people. Both the ancient Greeks and Romans described the Celts as redheads. The Romans extended the description to Germanic people, at least those they most frequently encountered in southern and western Germany.
One of the many facts about redheads is that their hair will never turn grey. The pigment in their hair that causes it to be red will just fade over time, causing their hair to turn blonde or white, but never grey.
Having red hair and blue eyes is the rarest hair/eye color combination possible. The odds of a person having both of those recessive traits is around 0.17%. Instead, most redheads have brown, hazel or green eyes, according to Medical Daily.
Previous studies had shown that redheads inherit two versions of the MC1R gene that leads to red hair – one from their mum and one from their dad. Although almost everyone with red hair has two copies of the red-haired version of MC1R, not everyone carrying two red-haired versions is a redhead.
The skin of a redhead is thinner compared to others and is derived from the ectoderm. Teeth enamel is also derived from the ectoderm and thus is thinner than usual. Since the enamel coating is thin, the inner layer of tooth-dentin is more visible and offers a yellowish appearance.
Redheads are less likely to go grey. The pigment in red hair typically fades over time from red to blonde and white, but not grey. Redheads produce more Vitamin D in a shorter amount of time than people with other hair colors.
But here's the thing. Despite its popularity, strawberry blonde hair only occurs naturally in between 1 and 2 percent of the world's total population — which means it takes hair color and technique to make it happen for the rest of us. In fact, it's a hue that's been rare yet in demand for centuries.
The rarest natural hair colour is red, which makes up only one to two percent of the global population. You commonly see these hair colours in western and northern areas of Europe, especially Scotland and Ireland. However, natural redheads may not exist for much longer.
Most redheads have a gene mutation called MC1R. This type of gene must be carried by both parents in order for a child to potentially be born with red hair. Lots of people carry the gene but don't have red hair themselves. This is often why we see red hair skipping a generation or even multiple generations.
Irish immigrants arriving in Australia looking for labour gained a reputation as heavy drinkers and fighters, with 'blue' being local slang for a fight. The term evolved to come to mean a redheaded Irishman.
Lifespan: up to 20 years in captivity, 5-10 years in the wild. Special Adaptations: Males have an elaborate courtship dance where they throw back their heads, almost touching their tail!
Natural redheads usually have fair skin with cool undertones, and it's a stunning combination. So if you have cool skin tones, opt for a natural auburn or mahogany shade.
Some evidence suggests redheaded adults often appear older than their actual age. For example, one study published in 2016 in Current Biology found that adults who carry two copies of the MC1R gene variant are more likely to look two years older than other people their age.
Fun Fact: Redheads tend to have thinner enamel than other people, and so the inner layer of dentin is more visible and appears more yellow.
Our parents can mark the enamel characteristics and these can be decisive for the coloring of our teeth. For example, the thinner the outer enamel layer of the teeth, the more yellow our teeth will be. Interestingly, this is a case that usually affects redheads.
They may be more sensitive to certain types of pain and can require higher doses of some pain-killing medications. However, studies suggest that their general pain tolerance may be higher. People with red hair also respond more effectively to opioid pain medications, requiring lower doses.
Throughout history, artists from Sandro Botticelli to Dante Gabriel Rossetti have mined the potent symbolism of red hair to alternately suggest promiscuity, sensuality, deviousness, and—above all—otherness for centuries.
A redhead is a person with red hair. Although sometimes it looks more like orange, “orangehead” isn't a thing. Only about one percent of the entire population is a real redhead. In England, a redhead is “ginger” haired.
