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.
Melanin is responsible for all the natural colors of hair you see. When a human gets older, cells all around will die more quickly. This means that there will be less pigment cells to stain the hair. The result is that the hair becomes colorless, or grey/white.
Put simply, 'achromotrichia' is defined as the absence or loss of pigmentation in the hair. 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.
Believe it or not, that's not what happens for most people who have red hair. Red hair is likely to take much longer to go gray than other hair colors because the pigment just fades over time instead of the follicle entirely stopping its production of pigment—a condition called achromotrichia.
Does strawberry blonde hair go grey? If you have naturally grey hair and your dyed hair isn't maintained, it will fade back to grey. However, natural strawberry blondes will never be grey! Their hair fades to blonde or white with age.
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.
Once achromotrichia starts to set in, your red hair becomes lighter and lighter. It can even fade to an orangey-blonde, copper-blonde or even strawberry blonde, until your reddish strands become silver or white. It's good to note, there's no timeline for achromotrichia.
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.
No-No's. 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.
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.
Darker hair colors like deep black, espresso brown, and blue-black tend to fade the slowest.
The aging process looks different for every redhead. In their 30s and 40s, some redheads may experience their hair starting to dull and fade into more of a strawberry blonde. Some redheads may experience the vibrancy of their red changing and their hair looking more brown.
In some individuals, the change in color of pubic hair may occur around the age of fifty, but it can happen earlier or later, depending on individual genetic predispositions and lifestyle factors.
Premature graying may be reversed with vitamin B12 supplementation only if vitamin B12 deficiency is the cause. If you are graying due to other factors, such as genetics, zinc deficiency, and medications, your gray hair cannot be reversed.
We have previously published findings that, after the age of 50, humans are seldom with- out gray hair. At this age, around 50% of men and 30% of women are moderately or totally gray haired.
According to an article by evolutionary biology professor Mark Elgar, PhD, of the University of Melbourne, blue-eyed redheads are the absolute rarest, with 0.17% of the population having that combination of hair and eye color. So if that describes you, you're most likely one in a million—or more!
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).
For a recessive trait to be expressed the individual must be pure breeding, hence two red heads can not produce any other colour in a child. If red hair is dominant, the chances are one in four that a child will NOT be a red head if mum and dad are both ginger nuts.
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.
Lifespan. Redheads can live as long as 21 years in the wild.

Eighty percent of redheads have an MC1R gene variant within the RHC. Red hair is also associated with fair skin color because the MC1R mutation also results in low concentrations of eumelanin throughout the body.
Moreover, red-haired individuals have been found to require significantly higher concentrations of desflurane for general anesthesia compared to those with dark hair. This increased desflurane requirement in redheads has been linked to mutations in the MC1R gene [20].
