People with albinism often have white or very light blonde hair, although some have brown or ginger hair. The exact colour depends on how much melanin their body produces.
While it may seem that only Caucasians have red hair, people from all races and ethnicities have ginger locks. It is more common in areas such as Northern Europe and specific parts of Russia.
However, redheads are not only Celts or Caucasians. Their distribution is a testament to the global movement of DNA across societies and landscapes. Although most common in Northern Europe, parts of Russia, and among European descendants in Australia, there are redheads from all ethnicities and races.
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.
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.
Other Sacharov redlines: "The connection between red hair and a fiery temperament may be more than just an old wives' tale. An Israeli psychiatrist reported that redheaded children are three to four times more likely than others to develop hyperactivity.
The rarest natural hair colour is red, which makes up only one to two percent of the global population. You commonly see these hair colours in western and northern areas of Europe, especially Scotland and Ireland. However, natural redheads may not exist for much longer.
Some evidence suggests redheaded adults often appear older than their actual age. For example, one study published in 2016 in Current Biology found that adults who carry two copies of the MC1R gene variant are more likely to look two years older than other people their age.
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.
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.
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!
Less than 2 percent of the world's population has red hair, making it the rarest hair color in the world. It's the result of the mutated MC1R gene. If both parents carry that gene, their child has a 25% chance of getting lovely, red locks, even if the parents don't have red hair themselves.
A redhead of African descent is pretty rare. Except when people are of mixed ancestry, red hair in Africans is usually caused by a kind of albinism.
In Asia, red hair can be found among some peoples of Afghan, Arab, Iranian, East Indians, Mongolian, Turkic, Miao, and Hmong descent. Several preserved samples of human hair have been obtained from an Iron Age cemetery in Khakassia, South Siberia.
Most redheads lack the ability to tan naturally (not that anyone should be out in the sun without an SPF50 anyway), so the only safe way to get a couple of shades darker is to implement a great fake tan routine.
Did you know that red hair is a genetic mutation? Both parents must be carriers of the mutated MC1R gene to be able to produce redhead offspring.
Most (natural) redheads will have brown eyes, followed by hazel or green shades.
The same mutation that makes their hair red is also what causes them to be more sensitive to temperature changes — even slight ones. They feel hot and cold temperature changes faster and with greater intensity than those with other hair colors.
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.
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.
#BLONDE! The contest for the most attractive hair colour is obviously won by the blonde color with 35% of the overall vote, followed by the brunette. The bronze goes to Pippi Longstocking (people 30 and above will understand ? ). And the fourth place is for black hair colour.
'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. It takes its name from the Italian renaissance.
