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).
Thanks to genetics, gingers tend to retain their red hair colour for a lot longer, skipping out the greying stage that most other people experience.
Celebrity hair stylist Nelson Chan offers some words of advice for women who want to maintain natural and youthful-looking red tresses during any stage of their life. For age 30 and under: This advice is usually for redheads 'by choice,' because natural redheads do not face intense fading until their 30's and 40's.
Lifespan: up to 20 years in captivity, 5-10 years in the wild.
Typically, white people start going gray in their mid-30s, Asians in their late 30s, and Blacks in their mid-40s. Half of all people have a significant amount of gray hair by the time they turn 50.
Grey hair and genetics
The average age for grey hair varies greatly, and one of the main causes of grey hair in your 20s is genetics. The age at which a person's hair turns grey is influenced by the IRF4 gene, and one specific variant (rs12203592) is a marker for premature greying.
Just like one finds grey hairs on the head upon ageing, appearance of grey hair on the eyebrows is also a sign of ageing/premature ageing. While for some, these signs start showing up in the 40's or 50's, some folks encounter the problem of grey hair on eyebrows in their 30's.
About 1–2% of people of European origin have red hair. Especially female redheads are known to suffer higher pain sensitivity and higher incidence of some disorders, including skin cancer, Parkinson's disease and endometriosis.
Most (natural) redheads will have brown eyes, followed by hazel or green shades.
Thanks to higher concentrations of red hair and pale skin in cloudy European environments, redheads gained a greater ability to create their own vitamin D. When they go outside, he or she produces more vitamin D in a shorter amount of time than people with other hair colours.
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.
According to research published in Current Biology, people with the MC1R gene, aka the gene that produces red hair and fair skin, tend to look several years younger than their non-ginger counterparts.
Redheads May Look Older
A study published in Current Biology found that adults who carried two copies of the MC1R gene variant typically appeared two years older than their same-age peers. Interestingly, this wasn't because redheads had more wrinkles, which you might guess since they're more prone to sun damage.
Researchers think that the ginger gene, known as MC1R, may cause the temperature-detecting gene to become over-activated, making redheads more sensitive to the cold.
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.
Recessive traits like red hair can skip generations because they can hide out in a carrier behind a dominant trait. The recessive trait needs another carrier and a bit of luck to be seen. This means that it can sometimes take a few generations to finally make its presence known.
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.
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%.
Most redheads have pink undertones in the skin which can appear ruddy.
Some studies indicate that redheads are more prone to illness because they prefer to keep out of the sun and so lack vitamin D, or because their ability to absorb the vitamin is less efficient.
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.
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.
Vitamins B6 and B12 have also been proven to boost melanin production. Goddard says that vitamin B6, also known as pyridoxine, has been found to trigger the production of enzymes and chemical reactions that boost the metabolism of the hair proteins (keratin and melanin) in the hair follicles.
BEST EYEBROW PENCILS FOR GRAY HAIR
If you prefer darker brows, consider trying dark brown, black-brown, taupe, or dark gray shades. If you prefer lighter brows, consider trying light brown, dark blonde, or light gray shades.
