Natural red hair is harder to dye than other shades. It 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.
If you want to color your naturally red hair, do it. Hair is just a form of self-expression and it will grow back. If you're worried you might have a tough time getting the color you want, the best thing to do is do a consultation with a hair colorist.
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.
As with any hair color and complexion, there are some “no-no's.” Avoid pastels since these colors tend to wash out those with red hair. Also avoid most oranges, yellows, and burgundy-reds. Yellow is really a wild card color— on some it looks unbelievably good, and others it washes them out!
Bleaching red hair can sometimes cause it to turn pink or orange, especially if the red dye is a bright or vivid shade. This is because red is one of the hardest colors to remove from hair, and it can be difficult to fully bleach out.
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.
When our red hair follicles stop producing its gingerish pigment, we instead fade from red through a glorious spectrum of faded copper to rosy-blonde colours, through to silvery-white.
Rarest kind of redhead
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.
Redheads Look Older Than They Are
That wasn't because redheads had more wrinkles, which you might guess since they're more prone to sun damage. The researcher showed the MC1R gene variant correlated to thinning lips, sagging skin along the jawline, and other visible signs of aging.
Because MC1R affects the body systemically, the mutation also dictates other differences in the ginger-haired. While it makes redheads more susceptible to sunburn, that very sensitivity to ultraviolet rays also allows their bodies to produce more vitamin D, which is essential to bone development and good health.
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.
Edwin Liem at the University of Louisville in Kentucky found that redheads are more sensitive to hot and cold, and are hurt by the cold at temperatures nearly 11 degrees Fahrenheit warmer than others.
However, people with red hair produce little of the melanin that is good at blocking the sun's harmful light, and produce more of the melanin that doesn't do as good of a job in blocking sunlight, making them more likely to get sunburned.
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.
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.
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.
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!
Research has shown that people with red hair perceive pain differently than others. 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.
Green is the rarest eye color in the world, with only 2% of the world's population (and fewer than one out of ten Americans) sporting green peepers, according to the American Academy of Ophthalmology (AAO).
Having natural red hair is rare (like, two percent of the population rare), so coming across someone with natural strawberry blonde hair isn't common.
Red is the rarest hair color, according to Dr. Kaplan, and that's because so few MC1R variants are associated with the shade.
Someone with red hair has two copies of the MC1R gene, receiving one from each parent. The gene also carries a certain mutation in most people who have red hair. It's this variant that has been identified as playing a role in why redheads may respond to pain drugs differently than others.
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.
During this time and throughout the 19th century, Britain occupied parts of Malaysia, home to the Red Ginger plant. Beautifully bright as a beacon, this fiery-headed plant caught the attention of many visitors to the country, and has been cited as one of the first instances of redheads being called 'Gingers'.
