Natural red hair is the rarest hair color in the world, only occurring in 1 to 2% of the global population. Since red hair is a recessive genetic trait, it is necessary for both parents to carry the gene, whether or not they themselves are redheaded.
Blonde Hair
But this isn't the case because blonde hair is the 2nd rarest natural hair color. Only 3% of the total global population is blonde.
It is caused by a variation in the Mc1r gene and is recessive. Red hair has the highest amounts of pheomelanin, around 67%, and usually low levels of eumelanin. At 1-2% of the population, it is the least common hair color in the world.
Of those four, green is the rarest. It shows up in about 9% of Americans but only 2% of the world's population. Hazel/amber is the next rarest of these. Blue is the second most common and brown tops the list with 45% of the U.S. population and possibly almost 80% worldwide.
According to the study, men and women both viewed people with brunette hair color as more attractive than those with any other hue.
Black hair is the darkest and most common of all human hair colors globally, due to larger populations with this dominant trait. It is a dominant genetic trait, and it is found in people of all backgrounds and ethnicities. It has large amounts of eumelanin and is more dense than other hair colors.
How rare is natural dirty blonde hair? This is a rare colour, as many women opt for more vibrant colours such as platinum blonde or blonde hair with highlights and lowlights.
If You Have Blonde Hair
Blonds get white hair just like brunets, but some blondes only appear to get a lighter blond while others experience their blonde hairs getting darker and duller as the white hairs begin to appear. Still, blondes can, over time, have a full head of white hair.
Both characteristics come from recessive genes, which like to come in pairs. Redheads probably won't go grey. That's because the pigment just fades over time. So they will probably go blonde and even white, but not grey.
Green, which is the least common eye color. Only 9% of people in the United States have green eyes. Hazel, a combination of brown and green. Hazel eyes may also have flecks or spots of green or brown.
This colour and length of hair is most attractive on a woman. Longer and lighter hair is the most attractive on Caucasian women, a study has found. Both lighter brown hair and lighter blonde hair are seen as more attractive than darker or black hair.
Natural red hair is the rarest hair color in the world, only occurring in 1 to 2% of the global population. Since red hair is a recessive genetic trait, it is necessary for both parents to carry the gene, whether or not they themselves are redheaded.
Genetics
If you notice white hair at an early age, it's likely that your parents or grandparents also had graying or white hair at an early age. You can't change genetics. But if you don't like the way your gray hair looks, you can always color your hair.
The title of rarest hair color/eye color combination belongs to red-haired folks with blue eyes. According to Medical Daily, both blue eyes and red hair are recessive traits, so the likelihood of both traits appearing together is actually pretty slim.
Black is the most common hair color worldwide.
Estimates say anywhere from 75% to 85% of the world's population has black or very dark brown hair. This may come as a surprise to anyone living in the U.S., where only around 7.5% of women have black hair.
Green eyes and blonde hair are a rare combination. The high concentration of green-eyed, blond-haired people in Liqian is thought to be linked to their ancestry.
Dark brown hair is predominant in the Mediterranean parts of Europe, the Middle East, North Africa, Central Asia, and South Asia. Very dark brown hair, easily mistaken for black hair, can be found occasionally in parts of East Asia.
Some consider white to be a color, because white light comprises all hues on the visible light spectrum. And many do consider black to be a color, because you combine other pigments to create it on paper. But in a technical sense, black and white are not colors, they're shades. They augment colors.
Thus, brunette includes the range of hair colors from brown to black. There is no specific and separate term for someone with black hair. However, people have suggested the term noirette. Note, also, that although the term brunette includes those with black hair, not everyone may agree.
