Individuals with lower levels of a melanin pigment called eumelanin are likely to have blonde hair. There is no single gene for blue eyes and blonde hair, but these adaptations are often found expressed together because the genes for each trait are located close together on the same chromosome.
The reason why these two traits are linked is that the genes responsible for hair and eye color happen to be close together on the same chromosomes.
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.
Blond hair and blue eyes are one of the rarest combinations in the world (though red hair and blue eyes is even more rare), but such a combination is commonplace in Finland.
Scandinavia, a region in Northern Europe, is known for its inhabitants with blonde hair and blue eyes. This is a generally rare combination to have in such large numbers. The blonde hair likely arose as an adaption to the climate along with lighter skin.
There's a little genetic tweak that makes the combination of red hair and blue eyes the rarest of them all.
What is the rarest eye color? Green is the rarest eye color in the world, with only 2% of the world's population (and fewer than one out of ten Americans) sporting green peepers, according to the American Academy of Ophthalmology (AAO).
Like its neighbor Finland, Sweden also has some of the highest rates of blond hair in the world. It is estimated that up to 78% of Sweden's population has blond hair, including a large swath where the frequency of blond hair is higher than 80%.
The rarest hair and eye color combination is red hair with blue eyes, occurring in less than 1% of the global population.
How Rare Is Dirty Blonde Hair? About 2 percent of the population are natural blondes, but it's a very popular hair color because many turn to hair dye to achieve it. Brighter blonde shades like ashy blonde and beige blonde are more popular choices than dirty blonde, so you can consider dirty blonde a bit more unique.
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.

"I think we do get more attention, but not just because our hair color is brighter," Veronica said. "Blonde stereotypes have been deeply ingrained in society. We are perceived as fun and bubbly, but also dumb and easy. The extra attention isn't necessarily a good thing."
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.
Naturally-occurring blond hair is primarily found in people living in or descended from people who lived in the northern half of Europe, and may have evolved alongside the development of light skin that enables more efficient synthesis of vitamin D, due to northern Europe's lower levels of sunlight.
By the Renaissance period, the genes for blonde hair had spread throughout Europe, and the color came to be prized as a cultural symbol of angelic purity and innocence. In the twentieth century, blonde hair gradually attained a more sultry connotation.
