Characterized by high levels of the reddish pigment pheomelanin and relatively low levels of the dark pigment eumelanin, it is typically associated with fair skin color, lighter eye color, freckles, and sensitivity to ultraviolet light. Cultural reactions to red hair have been varied.
Redheads feel hot and cold temperatures more severely than anyone else. In 2005, the University of Louisville discovered this hidden gift and hypothesised that the redhead gene, MC1R may cause the human temperature-detecting gene to become over-activated, making redheads more sensitive to thermal extremes.
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.
Natural redhead colors are typically more muted—they can range from pale strawberry blonde to deep natural auburn hair, with dozens of variations in between.
In fact, green eyes are the most common eye color amongst redheads 💚🤯 If you have green eyes, blue eyes or any other color — we gotta say, it's very DEMURE 👨🦰👩🦰
Natural red hair is the rarest hair color in the world. A mere one to two percent of people are born with auburn hair. The prevalence is slightly higher in the northern and western fringes of Europe, especially the British Isles (mainly Ireland and Scotland), than in the rest of the world.
Women with red hair color exhibited higher sexual desire and sexual activity, a higher number of sexual partners of the preferred sex, earlier initiation of sexual life, and lower sexual dominance (and therefore higher sexual submissiveness).
Redheads produce more pheomelanin due to genetic changes (called variants) in the MC1R gene found on chromosome 16. This gene provides the code for a protein called melanocortin 1 receptor that is located on melanocytes and is responsible for the type of melanin produced.
Nature's Rarest Palette: Red Hair Standing at the apex of rarity, natural red hair occurs in just 1-2% of the global population. This striking shade results from a specific genetic variant of the MC1R gene, requiring both parents to pass on the recessive trait.
Northern and Northwestern Europe
Scotland has the highest number of red-haired people per capita in the world, with the percentage of those with red hair at around 13%, followed by Ireland and Wales.
The Judeo-Christian understanding, as reflected in both the Old and New Testaments, is that all red-haired creatures, human and nonhuman, are reprobate, beginning with Satan and his league of demons.
However, having red hair can also be beneficial—redheads typically produce vitamin D better than other individuals with a different hair color. American Cancer Society. Risk factors for melanoma skin cancer. MedlinePlus.
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.
According to Cosmopolitan (aka the sex bible), redhead women have more sex than blondes and brunettes. This is based on two studies, one done in Germany and one in England. 2. Red hair is the rarest color in the world, making up less than 2% of the world population.
Research indicates that redheads have higher thresholds for pain and need less vitamin D than the rest of us thanks to the MC1R gene mutation, which gives their hair its hue.
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.
Strawberry blonde is lighter than red hair. 'It's extremely rare for people to have hair that is naturally a strawberry blonde color. Basically, strawberry blonde is mostly based on red tones, with blonde highlights dotted here and there.
A 2003 study showed that people with naturally red hair can tolerate pain up to 25% better than others. The results of another study conducted at the University of Louisville have shown that redheads are more sensitive to temperature changes.
As we age, our hair's production of pigment naturally decreases. This gradual slow-down in redheads specifically, is called Achromotrichia. Achromotrichia is simply the process by which the hair pigment slows down, until it eventually stops being produced altogether.
The MC1R (or melanocortin 1 receptor) gene determines hair, skin and eye color. If you're a redhead, your MC1R gene has a mutation—or possibly several. It's why redheads are so rare.
There is absolutely no truth to the persistent myths that mosquitoes fancy females over males, that they prefer blondes and redheads over those with darker hair, or that the darker or more leathery your skin, the safer you are from her bite.
The use of the term to refer to persons with red hair may be a reference to the spicy ginger root, an amplification of the stereotype that persons with red hair have abrupt tempers or are prone to violence.
Prior research has already put red-haired humans and mice into the spotlight, pointing out that they have a higher pain threshold. They also don't need as high of a dosage of pain-killing opioids, and they tend to require more anesthesia compared to people with non-red hair.
