Many people around the world are naturally black-haired. However, some have unique hair colours, which are uncommon and unlikely to find. Mostly, the colours are a result of genetic mutation alongside other factors. Interestingly, the same applies to eye colours, and, at times, they can occur simultaneously. So, which are the rarest hair colors and eye combinations in the world?
Black hair is, arguably, one of the most common hair colours in the world. Science estimates that around 75 to 85% of the world’s population has black hair. Mostly, the colour is more prevalent in Africa, Asia, and in some other parts of the globe, such as Eastern and Southern Europe, America, and Latin America.
In this regard, many people tend to overlook the occurrence of some rare natural hair colors. In some instances, some term them as congenital disabilities, which is scientifically incorrect. Others embrace them, taking them as a plus to their physical attributes.

Rarest hair colors on the planet
Generally, hair is categorized into four primary colours – black, blonde, brown, and red. Out of the four, black is the most common one. Below is a comprehensive summary of the unusual natural hair colors, and their percentage distribution in the world’s population:
1. Red hair – 1 to 2%
Red-haired people have the strangest natural hair color on the planet. The occurrence is most common in Ireland and Scotland. According to Healthline, both parents must have the gene for red hair to be expressed in their offspring. It is so because the gene for red-head is recessive.
Also, the possibility of it being expressed is low even when both parents carry it. Interestingly, such a couple is likely to have one out of four of their children being redheads. As a result, scientists estimate that around 1 to 2% of the global population is made of redheads.

4. Black – 75 to 85%
Black hair, unlike others, is the most common in most parts of the world. Generally, black-haired people make up 75 to 85% of the world’s population. In most instances, people with such hair are found in Africa, Asia, America, Latin America, Southern, and Eastern Europe.
