Only 2 percent of the world's population has naturally blond hair. If you narrow your sample to white people in the United States, that percentage goes up, but only to 5 percent.
Because blond hair tends to turn brown with age, natural blond hair is significantly less common in adulthood; according to the sociologist Christie Davies, only around five percent of adults in Europe and North America are naturally blond.
True blonde is also a rare hair color, and the Daily Mail reports that only 12.7 percent of women have pure blonde hair, and only 9.9 percent of men do. Surprisingly, many of the genetic differences identified by the researchers correlated with factors other than pigmentation like hair texture and growth.
Is blonde curly hair rare? Yes, natural blonde curly hair is rare. Only 2% of the population have this special trait.
The genes for blue eyes and blonde hair are recessive, meaning both parents must have the genes for them to be expressed in their offspring.
Blonde fact #4: Not all blondes have blue eyes
That's why so many people around the world have black strands and brown eyes. Lighter tint gives rise to lighter coloured eyes, including blue, but also varying tones of green and grey. So, just because you have blonde hair, it doesn't mean that you have blue eyes too.
Some sources, such as Eupedia, claim that in central parts of Norway, Sweden, Denmark, Iceland and Finland, 80% of the population is blonde, with natural fair-haired people in other Baltic Countries (Latvia, Lithuania, Estonia, and other parts of Scandinavia) making up 50-79% of the population.
Finland. Finland has the highest blond hair population by percentage of the total population. Nearly 80% of the population has blond hair, and an astounding 89% of the population has blue eyes. Blond hair and blue eyes are one of the rarest combinations in the world.
Is it possible for an adult with naturally blond hair to have brown eyes? Inheritance of eye color is more complicated than we had once thought. So the answer is yes, but the combination is extremely rare.
But some children with light hair, including towhead blonds, strawberry blonds, dishwater blonds and redheads, see their hair go dark brown by their 10th birthday. The reason for this change is because the amount of eumelanin in your hair increases as you mature, according to some research.
TIL The rarest natural hair color in the world is red, with only 1-2% of the world population having natural red hair.
A genetic mutation that codes for the blond hair of Northern Europeans has been identified. The single mutation was found in a long gene sequence called KIT ligand (KITLG) and is present in about one-third of Northern Europeans. People with these genes could have platinum blond, dirty blond or even dark brown hair.
While the study concluded that the average age for a woman to go grey is 33, it found redheads lose their colour at 30, brunettes at 32 and blondes at 35. For one in 10 women, those first grey hairs appear by the time they reach 21-years-old, while one in four women find their first grey by the age of 25.

So let's plug in what we know probability of blonde hair is 28.3 Probability or percentage of blue eyed people is 16.6%. And then the probability of both blond hair and blue eyes is 9.3%.
As the population grows and people have babies, the genes for less melanin will become more common. That makes the link between lighter eyes, hair, and skin tighter. So that's why you see people with blond hair typically have blue eyes!
2 Answers. Blond hair and blue eyes are characteristics associated with people from northern European countries such as Norway, Sweden, Finland, Germany, Denmark, etc. These people are said to look "Teutonic" which is a term the ancient Romans gave to a northern European tribe known as the Teutons.
There's a little genetic tweak that makes the combination of red hair and blue eyes the rarest of them all. The same Nature study mentioned above found that another gene variant, HERC2, interacts with both the MC1R gene and the OCA2 gene—and it can shut off the redhead gene while expressing blue eyes and blonde hair.
The international scientific team found a total of 124 genes that play a major role in determining human hair colour and, unexpectedly, discovered that women were twice as likely to be naturally blonde than men. In comparison, they also revealed that men were three times as likely as women to have black hair.
The United States has predominantly black and brown hair in the population, with 85 percent for black hair and 11 percent for brown hair. Authentic blonde hair makes up only two percent of the population, and authentic red hair, the rarest hair color of all, makes up only one percent of the American population.
Changes in hair color in kids and teenagers are most likely due to changing hormones. Hormones are chemical signals that the body uses to send messages between body parts. Changes in hormone levels can cause pigment genes to be turned on or turned off. This can happen in adults too!
Take this 2011 study from dating app Badoo, for example. A couple of thousand UK men were polled and 33.1% of them revealed they found brunettes more attractive than blondes. Though 29.5% found blondes more attractive, brown-haired beauties still edged ahead of the pack.
The State that has the most blondes and natural blondes is Minnesota. Minnesota has a background and history of Scandinavians and German ancestry. So it is not California. Are natural blondes rare among most of England (UK)?
No, they don't. Blonde hair seems to have appeared more than once in humans. Which means that different blondes trace back their blonde hair to different ancestors. This is actually true of a lot of different traits.
