Here's why. Red hair is caused by a recessive gene and it's not possible for this gene to simply die out. Even if there were no more redheads, people would still carry the recessive gene and that gene can appear at any time. Redheads may become rarer in the future, but they aren't going anywhere.
There's more research on the variations in human hair color than you might expect, and the science makes it clear that crimson locks are not becoming increasingly rare, nor will they disappear any time soon. It's a trait that dates to prehistory.
Redheads Look Older Than They Are
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.
6. People with red hair are more likely to be left-handed. Recessive traits often happen in pairs so commonly people with the gene for red hair also possess the trait for left-handedness.
The MC1R gene might actually make redheads look young
Studies have shown that the MC1R gene that is carried by redheads may actually help to reduce the effects of UV exposure and reduce inflammation in the body. Both of these factors might help redheads to appear more youthful.
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!
The intriguing results are that blond women were more frequently approached by men, whereas blond males did not receive more acceptances to their requests. However, in both conditions, red hair was associated with significantly less attractiveness.
Having red hair isn't the only thing that makes some redheads unique. They are also more likely to be left handed. Both characteristics come from recessive genes, which like to come in pairs. Redheads probably won't go 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.
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%. Great Britain also has a high percentage of people with red hair.
Natural red hair is harder to dye than other shades Headstrong as it is, ginger hair holds its pigment much firmer than any other hair colour. If redheads desired to dye their hair to any other colour (why would you?), it would only have a noticeable difference after bleaching the hair beforehand.
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.
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.
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 recessive gene that carries red hair has been traced back 50,000 Years when early modern gingers first appeared in the grasslands of Central Asia. Red hair was regarded in classical literature as the epitome of everything barbaric – but only when it comes to men. A redheaded woman is a force of nature.
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.
This can be tricky, since most natural redheads have either very light copper brows and lashes or barely-there blondish-white ones. That coloring poses a problem with too-dark mascara—if it isn't applied all the way to the lash line it's really noticeable.
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.
This was followed by a small study published in the journal Anesthesiology, which found that women with red hair required up to 20% more anesthesia to keep them sedated than did women with dark hair.
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.
The study of 10,878 people found blonde-haired white women had an average IQ of 103.2, compared to 102.7 for those with brown hair, 101.2 for those with red hair and 100.5 for those with black hair.
First up, studies have found that people with ginger hair are better in bed. This is because of a specific gene connected to redheads – the MC1R gene. This gene makes the individual more sensitive to touch than people with other hair colours.
Myth: Redheads' skin ages faster because it's so dry.
A dry, leather-like appearance and increased wrinkles are not due to hair color. Those with dry skin have a multitude of options available to them using today's dermatology.
