Does anyone have naturally black hair

Hair color is determined by the amount of a pigment called melanin in hair. An abundance of one type of melanin, called eumelanin, gives people black or brown hair. An abundance of another pigment, called pheomelanin, gives people red hair. The type and amount of melanin in hair is determined by many genes, although little is known about most of them. The best-studied hair-color gene in humans is called MC1R. This gene provides instructions for making a protein called the melanocortin 1 receptor, which is involved in the pathway that produces melanin.

The melanocortin 1 receptor controls which type of melanin is produced by melanocytes. When the receptor is turned on activated , it triggers a series of chemical reactions inside melanocytes that stimulate these cells to make eumelanin.

If the receptor is not activated or is blocked, melanocytes make pheomelanin instead of eumelanin. Many other genes also help to regulate this process. Most people have two functioning copies of the MC1R gene, one inherited from each parent. These individuals have black or brown hair, because of the high amount of eumelanin.

It is estimated that more than 90 percent of people in the world have brown or black hair. Some people have variations in one copy of the MC1R gene in each cell that causes the gene to be turned off deactivated. This type of genetic change is described as loss-of-function.

For these individuals, eumelanin production is lower, while pheomelanin production is higher, so they have strawberry blond, auburn, or red hair. In an even smaller percentage of people, both copies of the MC1R gene in each cell have loss-of-function changes, and the melanin-production pathway produces only the pheomelanin pigment.

The hair of these individuals is almost always very red. If we look at it under natural light, we can see reddish highlights. To achieve completely black hair, as black as night, you must use black hair dye.

Hair Color. Is there such a thing as natural black hair in humans? Or is it only achieved by dyeing the hair? What the human being visualizes as black is actually dark brown. We can visualize some red highlights because red is the underlying color of the hair that looks black. It means that the famous jet black, deep black, or night black can only be achieved with a hair dye.

What should you do if you want black hair? Brunettes are. In various media brunette women are pitted against blondes for the affections of men. Brunettes have a higher chance than those with any other hair color to become addicted to nicotine. The high levels of melanin in brown hair makes it difficult for their livers to metabolize the nicotine. However, many people, across all ethnic backgrounds, enjoy bleaching their hair blond, which accounts for the high number of blonds out there.
