You’ve probably seen some crazy hair colors before, but if you’re wondering which color is the absolute rarest, you’re in the right place. In this article, we’re going to take a close look at what the statistics and data say about rare hair colors. We’ll even break down why the colors are so rare in the first place. Read on to find out more.

What Hair Color Is Most Uncommon?

Red hair is the least common hair color. There are two types of melanin related to hair and eye color: eumelanin and pheomelanin. Most people have a combination of both, or very little of both. Redheads only have one type of melanin, which requires a gene mutation.

What is the rarest hair color on Earth?

1. 
   Red hair is the most uncommon natural hair color. Real red hair only appears in roughly 1-2% of the human population. It’s rare because it requires a very distinct combination of melanin levels that you (normally) only see in people with a specific gene mutation. So, not only is red hair recessive, but it requires a harmless gene mutation, too.

   Naturally red hair is exceptionally rare. Working as a hair stylist, you really get to see how uncommon naturally red hair is. A lot of people dye their hair red, but people who are natural redheads tend to take a lot of pride in keeping their hair natural.

Why is red hair so rare?

1. 
   Red hair requires a very uncommon genetic combination. Hair and skin color are controlled by melanin. There are two types of melanin: eumelanin (which is black) and pheomelanin (which is red). People tend to have a ratio of these two melanins based on their genes, but redheads have almost no eumelanin and plenty of pheomelanin. This actually doesn’t occur very often because it requires one specific gene to mutate, so it’s even rarer than blonde hair, which requires two recessive genes.

   • Melanin is why some redheads are pure “red” while others are “ginger.” Some redheads are closer to an orange shade than a pure red. These people have a little bit of pheomelanin and almost no eumelanin, while darker redheads have a lot of pheomelanin and a bit of eumelanin to tint it. Blondes have very little of either melanin.
   • Someone with black hair has a ton of both melanin types, while brown hair requires a little bit of each. Blondes don’t have very much of either melanin type, but since this

Rarest Hair and Eye Color Combo

1. 
   Red hair and blue eyes is the rarest eye and hair color combo. Red hair only appears in 1-2% of the population, and blue eyes are only found in 5-20% of the population (depending on where you live). As a result, blue eyes and red hair is the rarest combination, statistically speaking, at 0.17%. These folks have two sets of recessive genes and a mutation that triggers the redhead melanin ratio!

   • Aren’t green eyes the rarest eye color? Yes, and you’d think that makes red hair and green eyes super rare; while it is uncommon, that pair actually shares a natural genetic overlap the way blonde hair and blue eyes do. The genes for blue eyes don’t naturally appear very often alongside red hair, so it’s the winning combo prevalence-wise.

What’s the most common hair color?

1. 
   Brown and/or black hair is the most common. It’s estimated that roughly 90% of the world’s population has some variation of dark brown or black hair (it’s the same estimated percentage for brown eyes). This is a byproduct of genetics as well: the gene responsible for producing eumelanin, which adds black to hair color, is dominant, so the longer time goes on the more common black/dark brown hair will be.

   • Aren’t brown and black hair different? Not really, actually. Black hair is rarely 100% pure black, and the amount of black in the hair is determined by one type of melanin, so black and brown are really just variations of the same hair color. If you have a lot of eumelanin, your hair will almost look pitch black. If you just have a good amount of eumelanin, it’ll be a lighter shade of brown.
