Although human hair wigs has been widely used, the largest group of users is still African American women and African women. Although various human hairs are made of the same ingredients, they can still have many textures and sizes. As we have seen, the hair can be straight, wavy straight, wavy, curly, very curled and kinky. Kinky curly are mainly from Africans, while European and Asian hairs are usually straight or wavy straight hair. This kinky curly may be found mainly in Africa, and most have very curly hair and dark skin. It is puzzling that even though Africa has the greatest genetic diversity, the two ubiquitous features are skin color and hair texture. But why? Why do black people have different hair?
In fact, some people have dark skin instead of curly hair elsewhere. For example, Indians may be as dark as black people, but there are no black hair like blacks. In places like Melanesia, many people have dark skin and a variety of hair textures. Therefore, we can conclude that curls have nothing to do with skin color, but are related to the African continent.
Some people say that this is the result of weather and climate. Thousands of years ago, when people began to migrate and live in this world, they evolved and changed like other animals to adapt to their environment. Those who move to cold areas need more vitamin D in their skin and don't need too much melanin, so they look pale. And their hair becomes less kinky, so long straight hair or wavy hair can stay warm. However, because the equator passes through Africa, people on this continent live in a very hot climate. The denser the hair on the top of the head, the more it protects your scalp from the sun. Therefore, the ancients evolved extremely curly hair to protect them from the heat of the sun.
Another point is that since sweat is the way to cool our body, straight hair is more likely to stick to the body than curls, and straight hair seems to be a disadvantage. Perhaps it is natural to choose to eliminate straight hair, just because straight hair interferes with the body's ability to cool down. In any case, this may be the reason why Africans have different hair.
Therefore, natural selection leaves a group dominated by curly hair, producing more offspring than the previous generation of curly hair until everyone in this group has the same curly hair gene. Fortunately, there are human hair wigs in the world that allow them to change their hairstyles at will.
