1. As an industrial raw material, amino acids are manufactured.

The main component of hair is keratin, which accounts for about 97%. Keratin, on the other hand, is made up of amino acids. After chemical treatment, that is, hydrolysis with high concentration of hydrochloric acid, the hair can be decomposed into 28 kinds of amino acids, which can produce a large amount of animal nutrient solution.

and feed additives, which become raw materials for industrial processing.

2. Make wigs and hair extensions.

Hair is used to make works of art and for pest control.

1. Works of art: In the Victorian era, hair was used to make jewelry. As shown in Leila's Hair Museum, it is used to make hair wreaths, bracelets, necklaces, earrings, hat pins, cuff buttons, buttons, and much more.

The hair initiates a protective effect on the body.

1) Hair on the scalp can reduce head heat loss and protect the head from sun damage.

2) Eyelashes and eyebrows protect the eyes from sunlight, dust, and sweat.

3) Nasal hair can reduce the amount of dust and other foreign substances inhaled by the nasal cavity.

Hair is differentiated from the matrix cells of the lower part of the hair bulb and is divided into stiff hairs and vellus hairs. The hard hairs are coarse and hard, the color is thick, and the medulla contains medulla, and is divided into long hairs and short hairs, and long hairs such as hair, armpit hair, etc.;Short hairs such as eyebrows, nose hair, etc.

The role of hair is to keep warm and dissipate heat, protect the scalp, and having a thick black hair can also make people look more energetic and increase beauty. If there is a secretion disorder or often staying up late in daily life, it may cause hair loss, and in severe cases, it will also cause baldness, which will affect the overall image, and may also cause the patient to regulate the body temperature out of control. Usually, patients must choose a warm shampoo when washing their hair.

Hair also has a hemostatic effect. The head is feverish to ashes, and eating it with water can cause stomach bleeding.

1. It has a protective effect on the head. Thousands of hairs wrap around the skull, naturally forming the first line of defense of the head, which can protect the head from external mechanical and bacterial damage, play a role in the search for heavy fluids for physical health, and can also reduce and avoid external mechanical and chemical damage.

2. It can play a role in beauty. There is a bright black hair, neatly repaired, moderate length, when it appears in front of everyone, it gives people a chic and flowing beauty enjoyment.

3. It plays the role of excretion. Hair is also an excretory organ, and if there are heavy metals in the human body that are harmful to health, such as arsenic and mercury, they can be excreted from the body.

4. Hair can play a role in regulating body temperature. In winter, when the wind is cold and the blood vessels are constricted, the hair can keep the head in a certain amount of heat. In summer, the red sun is scorching, the blood vessels are dilated, and the hair can be noisy and radiate heat outward.

As a result, hair has the dual function of keeping heat both warm and cool.

1. Regulation: Hair can play a role in regulating body temperature. In winter, when the wind is cold and the blood vessels are constricted, the hair can keep the head in a certain amount of heat. In summer, the red sun is scorching, the blood vessels dilate, and the hair can radiate heat from the outside.

As a result, hair has the dual function of keeping heat both warm and cool. Hair is a fibrous tissue that grows from the scalp and is an arrangement of hard keratin formed by cell regeneration. Hair is made up of two parts: the root and the shaft.

2. Sensory effect: the feeling of hair is more sensitive, when the external environment has an impact on the human body, whether it is wind and rain, or sun and fire, the first thing to feel is hair, and the information sent by it is transmitted to the brain, so as to take a variety of protective measures.

Broadly speaking.

Hair is a type of hair. The basic function of hair is twofold: one is to protect.

The second is heat preservation. Therefore.

The hair that grows on the skull has the effect of protecting the head.

It will stand up in cold weather.

It's like a quilt with an insulating layer.

Weaken the blow of the cold on the skull in a narrow sense.

Hair is just a cell.

For metabolism.

And the real use of scientists is still undecided, but is the real role of hair really protecting the head? I understand it very well.

Many respondents may respond to this question with the idea that hair is used to protect the head.

Today I invite you to try to put aside the old scientific concepts.

Make a big assumption.

Taking the development of science to another level In a science fiction book "Hair" (Wesley), he once imagined that hair was a tool used by humans to communicate with aliens.

It's just that human science hasn't fully developed yet.

Hair is therefore only treated as a normal cell.

For the protection of the skull, of course.

This bold hypothesis about aliens is not the subject of discussion today.

But there is merit in questioning the true role of hair in the book. Today's science shows that hair is used to protect the head.

Think about it: the head is protected by a hard skull.

And how can you protect your hair from softness? Hair loss does not mean that humans are evolving.

Hair doesn't play a role at all?

Another step forward in science fiction** (Wesley) once fantasized that hair was a tool used by humans to communicate with aliens.

It's just that human science hasn't fully developed yet.

Hair can play a role in keeping our head warm, especially in winter, when the cold wind blows, if it is bald, it is easy to catch a cold, while people with thick hair are relatively less likely to get sick because of the cold on the head. Hair is a thing that accompanies people's birth body, but according to each person's genes, some people will have more hair, some people will have less hair, and then some people's hair is naturally straight, and some people are naturally curly, some people's hair is black, but some people's hair is golden, such as Orientals and Europeans and Americans, there are many differences in hair between them.

Hair is an organic substance that can be used to make fertilizer, absorb oil and water contaminants, and make a variety of products such as wigs.

Waste can be reduced through ** hair and the reuse of Ziqing Xiangyuan can be realized.

At present, there are a number of organizations and institutions that have started to collect hair and use it for pollution control and environmental protection.

At the same time, some Jinno hairdressers have also begun to send the cut hair** to relevant manufacturers to produce various products, which plays a role in environmental protection.
