Why do some people have curly hair, while others have straight hair?

Some people have curly heads and are born because their hair is oval, kidney-shaped, or oval. <>

Each of us has a different hair structure. Observe the crossed hairs under a microscope. It can be found that human hair starts out round, flat, oval, oval, kidney-shaped.

If it is round, the hair will appear straight and thick, and this type of hair is more oriental. If oval, the hair will be curly or wavy, which is more common in the West. <>

Hair protects the scalp and head. It can also help doctors diagnose diseases. There are many trace elements in human hair.

Detection of trace elements in hair can determine certain diseases in the human body. For example, major hospitals now have zinc clinics to check children for zinc deficiency, which is determined by hair testing. Some people have curly heads and are born because their hair is oval, kidney-shaped, or oval.

If oval, the hair will be curly or wavy, which is more common in the West. The reason why hair is curly or not curly is the shape of the hair follicles. Hair follicles are the cars that produce hair.

Some hair follicles are curved, and growing hairs are curved. A large part of it is that the shape of the hair follicle is determined by nature. But long-term stress is too much, or the mood is low.

People's scalps will be tense. Hair follicles are deformed to find space to grow. That's why some people have straight and curly hair when they're young.

By the way, I would like to talk about ion ironing. It breaks the structure of the hair with a liquid drug and then straightens it.

There are many reasons for unstraight hair, and the solutions are not the same. Too Dry - Puffy: Choose the right products and pay attention to hair care and maintenance.

Natural volumes- Puffy and curved: (this is a genetic problem that cannot be changed, only temporarily and non-permanently straightened).

It should be down to genetics. For example, Africans have the distinctive characteristic of curly hair in their genes, while the vast majority of Asians do not have this gene.

Because some people's hair can absorb nutrients, and some people's hair can't, it is said that some people are straight, and some people are curly.

In fact, it is mainly determined by genes, if the parents are naturally rolled, then it will be passed on to their own baby, and it may be that the race is different.

Hair has a great impact on human appearance, some people like curly hair, while others like to make their hair smooth and straight. Some people are born with curly hair, while others are born with straight hair, why do people have different degrees of curl in their hair?

Our appearance is genetic, parents, grandparents, and grandparents, so whether a person has straight or curly hair has a lot to do with heredity.

In China, most people have relatively smooth straight hair, but there are also a few people who have curly hair. Whether it's straight hair or curly hair, it's all related to genetics. Just like whether a child's eyes are big or small, double eyelids or single eyelids, all have a certain relationship with the appearance of the parents.

If you have an elder with curly hair in your family, then there is a possibility that the children in the family will also have curly hair, and even after a few generations, there will be curly haired children. Although everyone has a different level of affection for straight and curly hair,But whether it's straight or curly hair, it's all genetically determined.

The shape of the hair is determined by the hair folliclesBecause of the different shapes of hair follicles, some people have straight hair and some people have curly hair.

Hair grows in a hair follicle, and a single hair follicle is capable of growing multiple hairs, and the growth of the hair also depends on the hair follicle. The most important thing for us to take care of our hair is to take care of the hair follicles, only when the hair follicles are healthy, our hair will be healthy and soft. The hair follicles of straight hair are round, and there is no hindrance for hair to grow inside, so it will be straighter.

The hair follicles of curly hair are oval-shaped, and when the hair grows outward, the road is rough and there are many obstacles, so the hair becomes more curved. This is the reason for the formation of straight hair and curly hair, so we will see that some people have straight hair, while others have naturally curly hair, and even going to the barber shop to get it styling does not make the hair straight.

The influence of the environment on a person's physical appearance is very large. The growth and development of every living thing will change in order to conform to nature, soThe straightness and curls of human hair also have a lot to do with the environment in which they grow.

The environment in which we live is relatively favorable, and most people's hair is straight, and it does not affect us very much. But in African countries, Africans tend to have very thick and curly hair to protect their scalp from the scorching sun. Europeans who live in a better environment than Africans have a more natural curl of their hair, even if it is curly, and it is not as thick as African hair.

Therefore, some people are born with straight hair, and some people are born with curly hair, which also has a lot to do with their growth environment.

Many people with curly hair want to straighten their hair, and there are also many people with straight hair who perm their hair into curls. In fact, both straight and curly hair are healthy, and there is not much difference between straight hair and curly hair. Straight hair and curly hair are not much different in essence except for the fact that they affect a person's appearance.

Why are people born with straight hair.

It turns out that hair grows from some places on the scalp called hair follicles, and the shape of these hair follicles determines the shape of the hair. If the hair follicle is round, then the hair that grows is also round, and the hair is straight and soft; If it is oval, then the hair that grows out is also oval, and the hair is wavy; If it is flat, it will grow curls, like wool.

All this is determined by the genetics of the person. According to research, the curly hair of black people, as well as the role of blocking light and filtering, is very helpful in resisting the strong tropical sun. This is the result of the adaptation of humans to climatic conditions during the course of evolution.

This is related to genes, for example, if the dominant gene of curly hair is combined with the dominant gene, then the child born is curly hair, and if the dominant gene and recessive gene are combined, then it may be curly hair, or it may be straight hair.

Because there is genetics. Some people are born with curly hair because their parents or older generations have inherited genes. It was passed on to him.

The hair on each person's head varies greatly, and in addition to the color, the shape is also different. For example, one is straight, smooth and straight hair, which is mostly Asian, and Indians living in the Americas belong to this type; One is curly, wave-like hair, mostly Europeans and some South Asians, Southeast Asians; The other is curly hair, which grows on the head like a myriad of small springs, and the black hair of Africa is a representative of this kind of hair.

Hair grows from hair follicles, and the shape of these hair follicles determines whether the hair is straight or curved.

Hair is naturally curly because of the different genes of human beings, and most of them are genetic.

It is found in many races in the world, especially among the Caucasian race.

It is less common among Han Chinese, who live mainly in Asia. It occurs in both males and females, mostly due to genetic factors, and some are passed on from generation to generation. On the other hand, the size of the volume will be smaller than that of the Caucasian race.
