Black Hair Blue Eyes Facts

People with black hair and blue eyes can be found anywhere in the world. When you look at their origin specifically, those are from Central Asia, Europe and North Africa.

Many Pashtun of Afganisthan has this combination.

The European  countries like:

 Ireland

• Britain

• Iceland

have the highest population with these traits.

2. The spread of people with this genetic combination:

Today, people with blue eyes and black hair are not just limited to some Asian and European countries. You can spot them all over the globe.

Caucasian have this combination because when Arabs invaded them they gave black hair gene.  The intermingling of the Arab genes with those of the people from the European countries spread those genes far and wide. That is how this genetic attribute spread all over the world.

Over the generations, this genetic attribute spread further, which is why, these days, people with this hair and skin colour are all over the world rather than just being native to Asia and Europe.

3. Black Hair with Blue Eyes percentage

Are you wondering about the probability of having black hair blue eyes?

Your probability of having black hair and blue eyes is just 0.05%.

The percentage of black hair around the world is 90%. It is the most common hair colour. While the percentage of blue eye is just 8% worldwide. Therefore, you will realize that the percentage of individuals with such a combination is on the lower side.

4. No melanin content in Eyes:

The colour of the eye is present in the iris. Also, melanin is the compound that is present in the iris of the eye. A greater quantity of melanin will make the eye darker.

However, there is no compound that makes the eye appear blue. You might be thinking, then what is the reason behind blue eyes?

The answer is that when eyes do not consist of any melanin, all the light gets scattered when it is directed towards these eyes. That is what makes them appear blue. It is the reason why the sky or the sea appears blue.

Thus, the cause of blue eyes is not any specific compound present in the iris of the eye but rather the absence of melanin.

5. Higher Amount of Melanin In Hair

Hair colour is determined by what and how much amount of melanin pigment is present in hair.

Generally, there are two forms of melanin. i.e. Eumelanin and pheomelanin. 

Hair Color Type and amount of Melanin Secretion
Black A large amount of eumelanin
Brown Moderate eumelanin
Blonde Few Eumelanin
Red Pheomelanin

People who produce more eumelanin have dark hair, while people who produce moderate eumelanin have brown hair. In contrast, people who produce pheomelanin have blonde or light hair.

6. Hair Density Is Thin

Black hair is thicker as compared to the hair of another colour. Due to this very reason, in the same area, more hair can’t grow. It is one of the primary reasons why people with such genetic combinations often have thin hair.

In addition, due to high melanin, it has thicker strand and a lower hair density.

7. Climatic effect:

As I stated above, the region of people having this genetic combination is from Europe. However, have you ever wondered why only Europe and why not any other continent?

I will answer this question, as well.

In the North European region, which is the point of origin for such people, the sunshine is on the lower side. The skin needs sunshine to get Vitamin D. That is why; the skin attempts to absorb more sunlight because of its dearth. It happens not only for bone development but also for the robust immunization system of our body. That is why; these people have a high rate of sun absorption.

What many people might not know is that this evolution of the body to absorb more sunlight and get the pigment, which protects them from UV rays is on the lower side. That is because such people absorb as much UV rays as possible to get vitamin D. The pigment is by the same genes responsible for producing the pigment that colours the eyes and hair.

It means that the amount of that pigment is pretty less. That is why the eyes become blue in the absence of the melanin pigment.

In a nutshell, the colder climate in the North European region certainly impacts the hair colour and the eye colour of such individuals.

Another fact is that the population of people having black hair in northern Europe has been relatively higher for centuries. That is why; it is not that uncommon to have black hair. The absence of the pigment due to genes that produce UV resistant pigment leads to blue eyes.

Now you know why most people with this genetic combination might have a link to a single geographic region.

The next time around, you see an individual with black hair and blue eyes; you would at least know how rare that combination is. Not only that, but chances are also, their ancestors, if not them directly, would be related to northern Europe. These were some interesting facts about these individuals. These are individuals with some of the rarest genetic combinations in the world.

8. Black Hair Can Turn To Brown

People with blue eyes and born with black hair often do not have black hair throughout their life. You would be surprised to know that their hair colour can change to brown. Due to climatic condition, the production of eumelanin might decrease. When the production of this pigment slows down, your hair turns brown.
