What causes reddish hair, and what causes redness

Redness of hair can generally be seen in micronutrient deficiencies, malnutrition, vitamin deficiencies and other conditions. In traditional Chinese medicine, it is mentioned that there is a connection between the kidneys and hair, and when there is a change in hair, the theory of Chinese medicine is generally believed to be caused by a decrease in kidney qi and a deficiency of kidney qi. The main component of hair is keratin, which contains a variety of amino acids and trace elements, especially iron and protein deficiency is prone to yellowing and redness of hair.

Usually eat more protein-rich foods, eat more fresh vegetables and fruits, and mix meals reasonably, and eat more sesame, walnuts, beans, animal liver, Polygonum multiflori, etc.; In terms of medicine, vitamin B6 tablets and vitamin E tablets can be supplemented, and traditional Chinese medicine can also be used to tonify the kidney, which has a certain effect on the improvement of symptoms and the recovery of the condition.

1.Some people have red or yellowish hair, most of which is related to genetic factors. If the grandparents and parents have red hair or yellowish hair, the dominant genetic factor will be passed on to the children, so the children will also have this red hair color.

2.However, if the hair quality was very good before, black and bright, but the hair has been red and yellow recently, this situation should consider the existence of unhealthy factors, which may be the lack of qi and blood in the body, or the lack of some trace elements in the body, which will cause the hair quality to gradually change, and it is easy to appear red and yellow.

3.You can go to the hospital to check the trace elements, if this reason exists, it is necessary to increase nutrition every day, especially to eat some foods that have the therapeutic effect of black hair and blood, such as black beans, black sesame, red dates, ejiao, peanuts, walnuts, yams, etc., this kind of food can not only increase nutrition, but also replenish qi and blood, and have a certain therapeutic effect on improving hair quality. In addition, it is necessary to do a good job of sun protection every day, if it is often exposed to the sun, it will also damage the hair, and it is easy to make the hair dry, red and yellowish.

There are physiological and pathological reasons, some people like to dye their hair, which can change the hair texture over time, making the hair look a little redder. Some are genetic reasons, congenital redness of hair, caused by a lack of trace elements in the body, such as iodine, calcium or melanin, which can lead to malnutrition of the hair, resulting in reddish hair.

Causes of redness:

1. Genetic causes. Red hair mainly comes from thousands of years ago, a genetic mutation in the Nordics, that is, the MC1R gene mutation, everyone has the MC1R gene, but the MC1R gene in the red-haired people has a mutation. This mutation causes less melanin precipitation and more brown melanin precipitation, resulting in red hair and lighter color.

2. Overwork. The human blood contains two qualities, acidic and alkaline. If you work too long, overwork and consume too much physical energy, it will cause mental weakness, and at this time, the acidic hormone will increase in the blood, and the blood will be eroded, so the hair will appear red.

3. Lack of iodine in the body. When the hair is red and dry, it also means that there is a lack of iodine in the body, and the iodine in the human body is not enough, which may not only make the hair red, but also have hair loss.

4. Severe lack of protein. In some African countries, some children have red hair, which is caused by a severe lack of protein.

5. Take medications. Regular use of proprietary Chinese medicines containing cinnabar can cause hair redness.

6. Melanin deficiency. If melanin is distributed in a solution state, it often gives the hair a red color.

What causes hair rednessNowadays, more and more people like to dye their hair, and there are all kinds of hair colors. Everyone thinks that different hair colors will be a trend and fashion. However, if the hair is naturally red, few people pay attention to it, but in fact, the natural redness of the hair is a potential condition.

So what causes redness in your hair?

What causes hair rednessThere are many common causes of redness. For example, due to mental weakness due to excessive exertion and physical exertion, the acidic hormones in the blood increase and erode the blood, so the hair will turn red. If there is a lack of iodine in the body, the hair will become red, dry and dry, and may even lead to hair loss.

In addition, it may be due to a lack of protein, for example, in some African countries, some children have red hair, which is caused by a lack of protein. In addition, long-term use of medications containing cinnabar can also cause hair redness. There may also be a genetic reason, if the gene is mutated in the body, it will reduce the melanin in **, increase the brown and black, the hair will appear red, and the skin tone will become lighter.

Usually, we eat more fresh fruits and vegetables rich in alkaline substances, and eat less liver, meat, onions, etc., which cause too many acid toxins in the blood. Properly supplement iodine and calcium, eat more kelp, seaweed, small fish, shells and other foods rich in iodine to calcium. Stay in good spirits every day and don't overexert yourself.

Some parts of the hair color are bright and a little yellowish-red, which may be a genetic factor, but it is still recommended to check trace elements to rule out zinc deficiency.

Causes of yellowing of hair.

Cause 1: Hypothyroidism;

Cause 2: High malnutrition;

Reason 3: Severe iron deficiency anemia (hematology) and the initial recovery of major diseases lead to a decrease in melanin in the body, which makes the basic substances of black hair lacking, and black hair gradually turns yellowish brown or light yellow;

Reason 4: Frequent perming, shampooing with alkaline water or laundry detergent will make the hair damaged and yellow.

Causes of reddish hair:

1. Since iron is an essential trace element in the formation of black hair, when suffering from iron deficiency anemia, the hair can change from black to brown, which is equivalent to hair malnutrition.

2. Nutritional deficiencies have been observed in animal experiments, including long-term deficiency of protein, vitamin A, B1, B2, B6, folic acid, pantothenic acid or lack of copper, zinc and other trace elements, which can make mouse hair white, human hair thinning and thinning, dry and hypopigmented.

3. Hair color is related to genetics, which can be explained by examining trace elements in hair. Yellow humans have black hair and contain traces of copper and iron; Indians' hair is reddish-brown in color and contains copper and cobalt, and the formation of red hair is related to the "hair iron pigment" formed by the common release of protein, iron, and chromophores that are different from melanin.

The intake of trace elements is not enough, eat more codonopsis stewed new lotus root, black sesame paste,

Spend a lot of time in the sun, or often use gel water.

If you are malnourished, eat more nutritious things.

For example, hypothyroidism, high malnutrition, severe iron deficiency anemia and initial recovery from serious illness can lead to melanocyte synthesis in the body.

and the reduction of melanin secretion, the lack of basic substances that make hair black, resulting in the hair gradually changing from the original black to yellowish brown or light yellow. Other.

In addition, improper hair maintenance, frequent perm and hot blow-drying, washing hair with laundry detergent and alkaline water, over time will damage the hair and cause the color of the hair to change.

Normally, malnutrition will turn yellow, redness, if I haven't dyed my hair, I haven't seen it.
