Stick to your roots 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.
Natural red hair holds its pigment more firmly than other types. So even though its lighter appearance might make you think it would be easier to dye than dark brown hair, red hair needs to be bleached before it can be dyed.
Why do people sometimes appear to be younger than others of the same age? The culprit turns out to be an innocent-sounding gene, MC1R, responsible for producing, among other things, locks of fetching red hair as well as pale skin, researchers have discovered.
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.
For starters, redheads typically have fair complexions and are more susceptible to sunburn and skin cancer. Some people with red hair also experience pain differently, or they can look older than they are.
Lifespan: up to 20 years in captivity, 5-10 years in the wild.
Redheads actually have less hair than most other people. On average they only have 90,000 strands of hair while blonds, for example, have 140,000. However, red hair is typically thicker so it still looks just as full.
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.
They have a higher pain threshold
A McGill University study found that redheads could handle more electric shocks than those with different coloured hair. Other research discovered that gingers are better at handling stabbing or sharp pain.
Red hair is the result of a genetic variant that causes the body's skin cells and hair cells to produce more of one particular type of melanin and less of another. Most redheads have a gene mutation in the melanocortin 1 receptor (MC1R).
A new survey reported by the Daily Mail says ladies should start worrying in their 30s: specifically, ages 30, 32, and 35 (for redheads, brunettes, and blonds, respectively).
What Causes Redheads to Have Sensitive Skin? The mutation of the MC1R gene (the gene that regulates your skin pigmentation,) gives redheads their red hair. Unfortunately, the gene mutation also causes redheads to have thinner skin than most people.
Most (natural) redheads will have brown eyes, followed by hazel or green shades.
So, the answer to our question 'are redheads going extinct? ' is no. Redheads are less common and blue-eyed-left-handed-redheads are particularly rare, but they're not endangered and they won't die out due to that MC1R recessive gene.
Know Your Risk
As a redhead, or someone with a redheaded child, it's important to be aware of the risks of sun exposure to this particular skin type. Redheads carry a gene called MC1R, which increases a person's risk of developing malignant melanoma as a result of sun exposure[1].
To sum all that science up, red heads have a faulty MC1R receptor which doesn't switch on in response to the sun's UV rays. This means the yellow-red pheomelanin in their melanocytes cannot be converted into the brown-black eumelanin which creates a sun tan.
gingerphobia (uncountable) (UK, informal) Fear, dislike, or hatred of people with red hair.
It has long been known that redheads are at higher risk of sunburn and skin cancer. This is to be expected because red hair is associated with fair skin, which is more vulnerable to UV radiation [1].
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.
If both parents are ginger, their offspring would be ginger. Reason: We inherit half our chromosomes for our father (23) and half from out mother (23), 46 in total. If both parents passed on a ginger 'infected' hair colour chromosome, the child would be ginger.
The redhead gene
MC1R is responsible for producing the skin pigment melanin, which redheads can't produce because of the mutation. This same gene is responsible not only for hair and skin color, but also for the midbrain function that determines pain response.
Colliss Harvey's research found that redheaded individuals have higher levels of vitamin D, which is a source of strength. She asserts that this has been a contributing factor in stereotypes surrounding the foxy minority, which make up 2% of the global population.
They are typified as impulsive, quick-tempered, libidinous, and wild. The personalities of people with red hair are often believed to be imitative of their red hair, and they are seen as fiery, hot-tempered, hot-blooded, passionate, and angry.
When red hair follicles stop producing their gingerish pigment, the colour fades from red through a glorious spectrum of faded copper to rosy-blonde colours, through to silvery-white. It's a sight to be seen, giving an almost autumnal effect as your red hair moves into its 'silver fox' phase.
