What is the cause of the natural reddening or yellowing of hair, is it a lack of some kind of nutrit

The causes of yellowing of hair are also different from congenital and acquired. Congenital yellowing of hair is determined by genetics and racial differences, there is no good way**, most of the acquired yellowing of hair is caused by diseases, such as hypothyroidism, high malnutrition, severe iron deficiency anemia and initial recovery from serious illness, etc., which can lead to a decrease in the synthesis and secretion of melanin by melanocytes in the body, so that the basic substances of hair blackness are lacking, resulting in hair gradually changing from the original black to yellowish brown or light yellow. In addition, improper hair maintenance, frequent perm and hot blowing, washing with laundry detergent and alkaline water, over time will damage the hair, resulting in yellowing of the hair.

Dietary avoidance for the prevention and treatment of yellowing of hair:

For yellowing hair, in addition to the primary disease and strengthening the protection of hair, with a proper diet** can often receive more satisfactory results. The seaweed, kelp, turtles, shrimps and crabs in the diet contain a lot of iodine, calcium, iron, phosphorus, and a variety of fresh vegetables contain a lot of trace elements such as copper, iron, and cobalt, which are indispensable in the human body, and have the effect of promoting black and shiny hair. Iodine also enhances the synthesis and secretion of thyroxine, improving the blackness and shine of hair.

Eggs, lean meat, soybeans, peanuts, walnuts and sesame seeds contain a lot of animal and vegetable proteins, which can increase nutrition and improve nutritional status, and these foods also contain cystine and cysteine, the main components of hair, so they are also the best nutritious food for hair care. In ancient China, people used sesame seeds, black beans, Polygonum multiflori, etc. to make pills** hair yellowing and whitening, and the effect is quite good - it has been used to this day.

People with yellow hair should avoid sweets and fragrant foods.

Foods to prevent yellowing of hair :

Seaweed fish rolls, steamed hairtail, kelp stewed tofu, mulberry eggs.

Yellow hair in girls may be calcium deficiency Everyone knows that infants, nursing mothers and the elderly are prone to calcium deficiency, while adolescent boys and girls are prone to calcium deficiency, but few people know about it. After entering puberty, it is the second surge period of the human body, and the fast growth can grow 7 to 8 cm taller in a year, and the weight can increase to 4 kg. Generally speaking, you can "grow meat" with anything you eat, but bones must be calcium, and you can't grow bones without calcium.

Therefore, the calcium requirement during adolescence is particularly high. Adolescents who study indoors all year round and have less sunlight are prone to calcium deficiency. Because the ultraviolet rays in the sunlight can promote the absorption of calcium, without ultraviolet radiation, no matter how much calcium you eat, you will not grow into bones.

Calcium deficiency in adolescence is mainly manifested by night sweats, that is, sweating while sleeping; Hair is few, dull, and burnt yellow; Cramps in the calves (gastrocnemius muscles) when you sleep at night. To prevent and treat calcium deficiency in adolescence, the following points should be done: 1. Take calcium-containing drinks or medicines.

Such as taking active calcium powder or calcium lactate, multivitamin calcium, etc. It should be noted that after taking calcium products continuously for more than ten days, stop eating for 1 week, and then continue to eat, or within 1 week, eat for 3 to 4 days in a row, so as to ensure the need for calcium in the body. Some people say that if you eat too much calcium, you won't grow taller, which has no scientific basis.

2. Frequent sun exposure, let the ultraviolet rays in the sun promote calcium absorption, if you can't do it, you should take some cod liver oil appropriately. 3. Eat more fresh vegetables and fruits and foods with more calcium, such as shrimp skin and bone broth.

The most important is protein deficiency, followed by calcium, zinc, ammonium acids, etc.

Yellowing of hair is mainly caused by several aspects:

1. Lack of certain trace elements, such as iron deficiency anemia will lead to hair malnutrition, copper deficiency will affect the metabolism of melanin, zinc deficiency will affect the growth and development of cells, and hair will naturally turn yellow. Clause.

2. In terms of the physiological characteristics of hair, there is a hair follicle at the root of each hair, and there are hair mother exchange cells and hair mother pigment cells around it. Once these cell functions are disturbed and impaired, black hair turns yellow. Clause.

3. Washing your hair too often and washing your hair with alkaline soap can also cause your hair to turn yellow. Clause.

Fourth, some people think that eating food and fat are related, these substances are easy to produce lactic acid, carbonic acid, etc. in the body, and when there are too many acidic substances, the hair will gradually turn yellow. Clause.

5. When caused by a certain disease, such as systemic scleroderma and systemic lupus erythematosus, the hair will not only turn yellow, but also fall out in large quantities. Some people's hair turns gray and gradually turns yellow, which is mainly caused by mental stress, excessive fatigue, improper diet, and excessive sugar and fat, resulting in excessive lactic acid, glacial acetic acid, carbonic acid and other acidic substances produced by the metabolic process in the body. In view of this situation, we should make sure that life must be regular, pay attention to the combination of work and rest, and avoid excessive mental tension and fatigue.

The diet should be rich in iodine, calcium, and protein. Eat more kelp, seaweed, fish, fresh milk, eggs, soy products, and eat more iron-containing foods. Because iron has an inhibitory effect on acidic foods, such as pork liver, beef liver, onions, etc., it is easy to cause too much acidic substances in the blood, and these substances should not be eaten more.

Excessive perming will also lead to yellowing of the hair, so it is generally more appropriate to perm once every 3 months to half a year. It is necessary to wear an umbrella when going out in summer, because the hair will also be damaged by long-term ultraviolet rays.

Yellow hair doesn't necessarily mean something is missing. Yellow hair can be divided into two categories: primary and secondary, if it is primary, that is, the hair color is yellow after birth, there is no intermediate change, mostly related to gene expression, it is very normal, not necessary. If it is secondary, i.e., the original hair color was black and later turned yellow, it is necessary to consider that it is related to blood deficiency.

Traditional Chinese medicine says that hair is not only blood, but when there is a problem with the blood, it cannot nourish the hair roots well, and the hair color will turn yellow. For this kind of situation, generally after nourishing yin and nourishing blood, the hair color is gradually turning black, and it is recommended to take oral foods such as black sesame, black beans, black rice, etc., and the main drugs are raw land, cooked land, angelica, Chuanxiong, peony, etc. Due to the certain liver and kidney toxicity of Polygonum multiflori, oral administration is not recommended.

Yellow hair is mainly a symptom of zinc and iron deficiency, but it is not a disease.

As long as you take good care of your diet, eat more foods that contain zinc or high iron content, and if you are deficient in zinc, you can eat animal liver, peanuts, black fungus, walnuts, etc. Iron deficiency should be supplemented with iron, adjust the diet to avoid spicy and greasy food, low-calorie and high-protein food animal liver, lean meat, pork ribs, eggs, dairy products, beef and mutton and other foods, eat more fresh dark vegetables, fruits, not picky eaters, can better improve hair quality.

Yellow hair is a sign of zinc deficiency, and it is enough to drink zinc gluconate oral solution or eat zinc-containing foods.

Yellow hair is a lack of vitamin B It is recommended to eat more fruits and vegetables, the kind that is very cheap in pharmacies, nutrition is a species that human beings must rely on to survive, and can enable human beings to maintain normal life, grow the body, daily activities, especially during the peak period of human growth and development, it is necessary to ensure that sufficient nutrition is given, so that the vitamins and minerals in the body are balanced.

Yellow hair is usually considered to be anemia, as well as vitamin and zinc deficiency, if the laboratory test is normal, it is recommended to take appropriate zinc and vitamins in combination with the symptoms, pay attention to a balanced diet, and eat more high-quality protein-rich foods with proper nutrition.

Not necessarily, some people are born with less melanin, which varies from person to person.

There is such a suspicion.

Yellow ends are sometimes normal. Because the nutrition is not so low.

You can comb and cut your hair frequently. Pay attention to nutritious eating.

One of the possible reasons.

It can also be genetic.

One of the main factors that causes yellow hair is high malnutrition, at this time, experts recommend that we should pay attention to the adjustment of diet, and should take a comprehensive intake of various nutrients in daily life, only in this way can we improve the nutritional status of the body. People with yellow hair loss in daily life should try to eat more eggs, lean meat, soybeans, peanuts, walnuts, black sesame seeds and other foods, which not only contain a lot of animal protein and vegetable protein, but also contain cystine and cysteine, which constitute the main components of hair, which are the best foods for hair care.

The yellowish hair is related to the increase in acidic toxins in the blood, as well as overwork and overeating sweets and fatty foods. If you overwork and eat too much sweet food, it will change the body fluids and cause the body fluids to become too acidic, in which case it is easy to cause the hair to turn yellow. You should try to pay more attention to rest and not be overly tired, and at the same time, you should try to eat more kelp, fish, fresh milk, beans, mushrooms and other foods.

Fresh vegetables and fruits are also indispensable, such as celery, rape, spinach, bok choy, citrus, etc., which are conducive to neutralizing acidic toxins in the body and improving yellowing.

What is the cause of yellow hair, it is likely to be caused by a lack of copper. If there is a lack of "tyrosinase", which contains an important copper, in the process of producing melanin, if there is a lack of copper in the body, the activity of this enzyme will be seriously affected, resulting in yellowing of hair. This group of people should try to eat more copper-containing foods, such as animal liver, tomatoes, potatoes, celery, fruits, etc.

There are many reasons for yellow hair, if you have been engaged in some computer, radar and other work for a long time, the hair will also appear yellowish, so in the question of what is the cause of yellow hair, this is also one of the factors.

There are also many reasons for yellowing hair:

1. Genetic factors;

2. Severe iron deficiency anemia and initial recovery from serious illness lead to a decrease in melanin in the body, resulting in a lack of basic substances in black hair, and black hair gradually turning yellowish brown or light yellow;

3. High malnutrition;

4. Frequent perm, shampoo with alkaline water or laundry detergent;

5. Hypothyroidism.

It has a lot to do with the increase in acidic toxins in the blood.

There are many factors that contribute to yellowing hair, and malnutrition is just one of them.

Yellowing of the hair is most likely caused by a lack of copper.

Except for congenital is a sign of malnutrition.

No, it may be genetic, or it may be that you always toss your hair.

Not necessarily. Maybe you were born with this hair color.

Not necessarily, it may be caused by a lack of attention to hair maintenance.

Not necessarily, but it may be congenital to be such a color.
