Hair color of immigrants

Because most people in the United States are white, that is, Europeans and Americans, followed by blacks, the hair of these two races is naturally curly, while the hair of Europeans and Americans is mainly brown and yellow, which determines whether your hair is straight or curly and the color. The most important thing is DNA, so their curly hair is natural. On the contrary, native Indians in the United States, like Asians, have straight yellow skin. Of course, these genes.

As we all know, people in every place look different. For example, Europeans and Americans have relatively white skin and curly yellow hair, while African blacks have relatively complete hair and particularly dark skin, which will not turn white no matter what environment they live in. For example, we East Asians have straight and black hair, yellow skin and black eyes, while many girls in the United States have yellow curly hair, although the United States is an immigrant country. But because these immigrants are mainly white, they continue the appearance of Europeans, and the natural color of their hair is the same as that of Europeans. The rest are made up of black people. Their hair is curly, but they have black hair.

The most important reason for their curly hair is the DNA gene, which has decided whether your hair is straight or curly, so most foreigners' hair is naturally curly, even if it is straight later. There is another reason, which is related to the climate in two places. Their hair is curly because Africa is quite hot and ultraviolet rays are extremely strong. This can prevent the scalp from being radiated by the sun, and the climate in most parts of European countries is relatively cold, so curly hair can also protect your scalp from frostbite in cold weather, which is scientifically based.

East Asians have straight hair because the weather is neither too cold nor too hot, like most parts of East Asia have temperate climate, so people's hair grows naturally. Of course, there are some exceptions. For example, as the climate and culture of ethnic minorities in Xinjiang gradually move closer to Europe, their curls are relatively high and their beards are much thicker than those of Han people.
