Why do people have two spirals on their heads?

The hair shaft inclines to the skin. Many hairs are inclined in the same direction, which is called hairflow or hairflow. The flow of hair on the top of the head can form a spiral arrangement of the center outward and the surrounding hair, commonly known as hair spinning.

Usually people have a hair spin, mostly located on the top of the head, or left and right. A few people have two or three hairpins, some of which are located at the front of the head, forming a special hair stream. The position of the hair spin has a certain influence on the hairstyle. It is difficult for people with many hairstyles to comb and do their hair styles. Therefore, understanding and mastering the growth law of hairflow is conducive to better hair design.

There are some sayings about numbers among the people, but they are not completely correct.

It is logically related: otherwise, why are all people the same, and only a few people are special? It shows that the physiological characteristics of these few people are different from those of most people, and their physiological factors such as metabolism and blood circulation are also different from those of most people. Therefore, this will certainly have an impact on his character. But the day after tomorrow, most of them lived for a long time and gradually assimilated with it, and the difference was not obvious. Of course, there are still a few. This is the reason why fortune tellers talk nonsense about this problem.
