A friend once joked that to judge whether a person is really black, no matter what color he is, just put a pencil in his hair and turn it back and forth, left and right a few times. If the pencil hadn't fallen, he would be of black descent. The reason is that black hair, whether male or female, is compact and small, layer by layer, but the total length of each hair will not exceed two or three centimeters. With hair like this, the pencil won't fall off when it is inserted. Once this kind of curly short hair grows, the ends of the hair begin to curl back and forth, as if it would not stop until it got into the skin, making the scalp itchy and prickly, like being bitten by a bug. So black people either shave off all their hair or braid their real hair into wigs.

But for beauty and comfort, blacks are still willing to use wigs. Most of the wigs they use are synthetic, and some of them are particularly strange. They look like the hair of animals or birds. Others simply use a rope made of wool or acrylic thread instead. The color is stranger than you and I imagined. Of course, there are wigs made of human hair, but they are extremely expensive. However, both synthetic wigs and wigs made of real hair are woven with black real hair, so it is no longer difficult to distinguish between true and false. It's all black hair.
