Black hair is the darkest and most common of all human hair colors globally, due to larger populations with this dominant trait. It is a dominant genetic trait, and it is found in people of all backgrounds and ethnicities. It has large amounts of eumelanin and is more dense than other hair colors.
What is this? To sum things up, naturally black hair does not exist. The only way to get truly black hair is to dye it yourself or with the assistance of a professional colorist.
Unlike white and other hues, pure black can exist in nature without any light at all. Some consider white to be a color, because white light comprises all hues on the visible light spectrum. And many do consider black to be a color, because you combine other pigments to create it on paper.
Black hair is most common in Asia and Africa. Though this characteristic can also be seen in people of Southern Europe it is less common. People of Celtic heritage in Ireland with such traits are sometimes known as the "Black Irish". Hair is naturally reflective, so black hair is not completely dark in bright light.
That's how we see the spectrum. But, because of this 3-cone physiology, we can also see combinations of red and blue that don't actually occur in nature. They are not part of the visible spectrum. Purple isn't a real color.
Red hair is the rarest natural hair color. Experts estimate that somewhere between 1-2% of the world's population has red hair. Red hair is more common in Scotland than anywhere else in the world, where 13% of the population are redheads.

Blue hair does not naturally occur in human hair pigmentation, although the hair of some animals (such as dog coats) is described as blue. Some humans are born with bluish-black hair (also known as "blue black" hair), which is black that has a blue hue under the light.
African hair produces plenty of protective oils, called sebum, which keeps our hair healthy. In fact, African hair actually produces more oils than Caucasian and Asian hair. However, due to the tight curls, the oil doesn't spread evenly along the hair fiber. Without lubrication, the fibers can become dry.
Origins. Red hair is the rarest natural hair color in humans. The non-tanning skin associated with red hair may have been advantageous in far-northern climates where sunlight is scarce.
Thus, brunette includes the range of hair colors from brown to black. There is no specific and separate term for someone with black hair. However, people have suggested the term noirette. Note, also, that although the term brunette includes those with black hair, not everyone may agree.
Despite the claims made online and by product marketers, it's not possible to reverse white hair if the cause is genetic. Once your hair follicles lose melanin, they can't produce it on their own. As melanin production slows, your hair turns gray, and then white when melanin production has completely stopped.
In most of Japan's public schools, pupils are only permitted to have straight black hair. They cannot bleach, dye or perm it. Conversely, any student whose hair is naturally light or curly can be made to straighten or dye it until it is the required shade of black.

But this isn't the case because blonde hair is the 2nd rarest natural hair color. Only 3% of the total global population is blonde.

Red-green and yellow-blue are the so-called "forbidden colors." Composed of pairs of hues whose light frequencies automatically cancel each other out in the human eye, they're supposed to be impossible to see simultaneously. The limitation results from the way we perceive color in the first place.
