Have you ever wondered why human hair grows whirling?

The head spin, also known as the "hair spin", is the first place on the top of the head where hair grows. In order to make the hair grow evenly and tightly all over the scalp, the hair strands, like sunflowers, start from a central point and grow according to the Fibonacci sequence, the spiral trajectory. In this process, the hair grows locally in one direction, and the center point forms a vortex, that is, a hair vortex.

According to the research of Chinese anthropologist Wu Rukang, most people have a single spin, less than 10% of the people have double spins, and only three spins. What exactly is causing this difference?

Generally speaking, as long as there is a hair spiral on the head as the center point, it can make people grow hair. However, due to the difference in genetic environment, some people will grow two or even several center points on their scalp, and there will naturally be more hair spinning. No matter how many hair spins there are, it is a normal physiological phenomenon.

The whirlpool of hair is where hair begins to grow. Since the human hair does not grow straight out, but obliquely from the top of the head, there is a small void left in the middle of the place, which is the hair swirl on the top of the human head.

No, but I've heard that Changxuan is a sign of intelligence.

Analysis: The hair shaft and ** are inclined to a certain extent. Many hairs are tilted in the same direction and are called hair flow or hair flow. The hair stream on the top of the head can form a center outward, and the surrounding hair is arranged in a swirling pattern, commonly known as hair swirl.

Usually people have a hair whirlpool, mostly on the top of the head, or to the left or right. A few people have two or three hair whirls, and some have hair whirls located at the front of the head, forming a special hair. The position of the hair spin has a certain impact on the hairstyle.

It is difficult for people with a lot of hair to comb, and it is more difficult to make hairstyles. Therefore, understanding and mastering the growth law of hair flow is convenient for better hair styling.

The shape of the hair varies depending on the race. The hair of the yellow race is straight, cylindrical, thicker, rounded in cross-section, and yellowish; The morphology of Caucasian hair is quite varied, it can be straight or wavy, the cross-section is oval, the color is black, golden yellow or white, the black hair is finely curled, black, the cross-section is oval, but one side is flat, its fur is obviously twisted, and it is susceptible to damage by external factors.

The straightening of the hair is related to the morphology of the hair follicles. The hair follicles are cylindrical, and the hair that grows is straight; The shape of the hair follicle is oval or oval, the hair that grows is wavy or curly, and the irregular growth of the hair bulb is also related to the formation of the hair in a wavy shape.

Hair spinners are mostly innate, everyone has hair spinders, but a small number of them are caused by acquired injuries. "One spin is horizontal, two spins are twisted, and three spins are not fatal. "By the number of these whirlwinds, you can judge a person's character.

Animals also have hairy spindles on their bodies. There are a few people who even twist their eyebrows, and the hair whirls are innate. Just like fingerprints, the root lies in the genetic control of the human body.

Affected by gravity, the hair is supposed to grow downward, but the head is round, calculate the force generated by the hair and the force between the hair and the hair, the hair grows with the least force, and naturally it grows as much effort as possible.

Are you paying attention to your hair? Our hair grows in a runway all around. It's okay if it still grows on the top of the head, but the problem is that our head is round.

The average density of hair is the same, and there will be unevenness at this time. This is what we call spinning. One, two, or three, depending on how the person's hair transitions when it is on the top of the head, different transitions become different spins.

It's just that according to your head shape, the hair can't all be a long, so there is, and I don't know the specifics!

Because the long spin is cute.

Maybe it's Shuai Ba. o(∩_o...Ha ha.
