From fiery reds in Scotland to golden blond shades in Scandinavia, every color tells a story. So in this video we are going to explore the fascinating links between hair color and ancestry. Now there are 4 main natural hair colors, each with several shades. Black is the most common hair color in the world, at around 75-85% of the population. The second most common is brown, at 11-15% of people. Blond is much rarer. Only 2-3% of people around the world have natural blond hair, and red is the rarest hair color on earth, found in only 1-2% of people. Certain colors like auburn blend red and brown tones, but auburn hair is not considered a separate category. Obviously people of a certain age also develop gray or white hair a lot of the time, but their original hair color was within these 4 types. People with albinism also typically have very light or white hair. This is caused by genetic mutations resulting in little to no melanin being produced. But let’s focus on these 4 main hair colors and their links to your ancestry, and let me know what your hair color and ancestry is in the comments below. First up is the rarest hair color in the world, red hair, but what causes this color? Well red heads have a variant of the melanocortin-1 receptor gene (or MC1R) located on chromosome 16. This is involved in melanin production and is the primary driver of red hair, although other genes do play a role. It’s color comes from varying levels of different types of melanin. Red heads have high levels of the reddish pigment, pheomelanin, and relatively low levels of the dark pigment, eumelanin. Red hair is also considered a recessive trait, so you need to inherit one mutated MC1R allele from each parent to have red hair. Now look at this table. It shows the regions of the world with the most amount of people with naturally red hair. As you can see, it is most common in Europe at around 4-6% of the population. Yet it is also at similar levels in North America which is interesting, and this is due to the European influence, especially people of Scottish and Irish descent. And this table shows the countries that have the most red heads on earth. As you can see, Scotland and Ireland are at the top, with another Celtic speaking people also relatively high, the Welsh.
