My hair is less white, but the hair in other places is very black and very black.

There are many reasons for less whiteheads, such as genetics, malnutrition, high pressure in study and life, etc., usually pay attention to strengthening exercise, and increase black beans and black sesame seeds in the diet. There is a post of traditional Chinese medicine: 10 grams of lotus grass, 10 grams of ligustrum, 5 grams of shou wu, decoction, once a day.

It's best to see a doctor.

Hair grows from a hair follicle, and one hair follicle grows an average of 2 4 hairs. The color of hair is determined by the melanin secreted by the hair mother cells in the hair follicle. Melanin particles are abundant and dense, while hair is black and light in color.

There are many reasons that affect the secretion of melanin, for example, generally after the age of 40, the melanin produced by melanocytes will gradually decrease, and genetic factors, malnutrition, mental stress, lack of sleep, and poor digestive function will also affect the secretion of melanin, resulting in the appearance of gray hair.

The lack of whiteheads is caused by spleen deficiency, and the graying of hair in the elderly is caused by the fact that the melanin particles of the person will slowly decrease with age.

White hair is thicker than black hair, just an illusion in the naked eye, white hair and black hair are the same, the thickness is about the same, and the stored ingredients are about the same, the difference is that there are a large number of melanin particles in the fur of black hair, and there are no melanin particles in the fur of white hair.

Causes of gray hair:

1. Diseases and genetic factors.

There is often a family history of low whiteheads, and certain syndromes (eg, progeria syndrome, comprehensive myotonic dystrophy, etc.) may be present. In addition, gray hair can also occur when suffering from some more serious diseases, such as pernicious anemia, hyperthyroidism, cardiovascular disease, tuberculosis, typhoid fever, syphilis, etc.

2. Too much pressure.

Mood changes can easily make the body's nervous system dysfunctional, so the function of melanin secretion will also be impaired, affecting the synthesis and transportation of pigment granules, and a lot of gray hair will grow.

Some young people have a large amount of gray hair in a short period of time, which is closely related to severe mental trauma or excessive fatigue such as high work pressure, excessive anxiety, sadness, etc. Due to negative emotions such as extreme tension and sorrow, it often causes a series of sharp changes in the body, resulting in serious endocrine imbalance and gray hair in a short period of time.

3. Lack of trace elements.

Studies have shown that protein deficiency and high malnutrition are one of the causes of early gray hair, especially the lack of trace elements such as copper, cobalt, and iron in the diet can also lead to gray hair. In recent years, scientists have found that the pigment particles of hair contain a mixture of copper and iron, and when the nickel content of the hair increases, it will turn grayish-white. Therefore, trace elements are closely related to hair color.

4. Lack of vitamins.

Medical studies have found that the lack of vitamin BL, vitamin B2, and vitamin B6 is also an important cause of fewer whiteheads. Foods rich in B vitamins, such as cereals, legumes, animal heart, liver and kidney, milk, eggs and green leafy vegetables, should be consumed. Traditional Chinese medicine believes that hair is not only blood, but also the main bone of the kidney, and its bloom is in the hair, and it is advocated to eat more food that nourishes blood and nourishes the kidneys to nourish the hair.

According to your description, it should be white hair slowly turning black.

Because for the hair, the part of the hair that is close to the roots of the scalp is relatively freshly grown.

Yours is black near the roots and white on the outside. That is to say, the white hair that used to grow out of the roots has been slowly turning black, and even the hair that has grown out of the roots has been completely black.

The hair has turned from black to white, and it is a clump of hair that turns white at the same time, no longer just a few gray hairs like in the past, which shows that you have reached the transition stage of your age: really old! Soon, the gray hair is yours!

60 years old, full of gray hair, there are many people, not alone. Therefore, most people are dyeing their hair...

Gray hair is mainly caused by blood fever, liver and kidney deficiency, and loss of qi and blood. We should maintain a happy spirit, pay attention to the combination of work and rest, adjust the dietary structure, and guide: eat more of the above-mentioned foods rich in vitamin B group and foods containing trace elements such as copper, zinc, iron (such as black sesame, walnuts, etc.).

Proper head massage increases scalp blood circulation and is also conducive to promoting the synthesis of melanin granules, resulting in darker hair.

It's because the hair is going to turn gray, half of the reason is genetics, and half of the reason is that there is a physical problem

Generally, the part that has just grown is black, and the part that has grown before will turn white.

This is because there is a process of hair graying, and in this process, new hair grows, so this happens.

It is because your body has decreased melanin secretion for a period of time, resulting in gray hair, and after a period of melanin secretion is normal, there will be long black hair.

You belong to black and white impermanence.

It's black on the top, and then it's all white at the root.

To avoid embarrassment or dye the hair handle.

From white to black, if the root part of the hair is white and the outside is black, it is from black to white.

White hair is white from the beginning.

Many people, including myself, deliberately avoid the issue of age because they are afraid of getting old. If you see one or two gray hairs on your head, you can't wait to pull it out as if you have found an enemy, and you will definitely pull it out with the killer. Because gray hair means old age, no one likes gray hair.

So, is it a good thing that the gray hair suddenly turns black? I don't think it's necessarily a good thing, people are old, the body's functions have changed, hormone levels have decreased, so gray hair will be produced, if gray hair turns black, it may be related to hormone changes, you have to go to the hospital for a full body examination.

1. The sudden darkening of gray hair may be related to hormonal changes

When you are young, when the level of estrogen is high, you will maintain the balance of various functions in the body, the endocrine balance, the person looks very energetic, and the hair is black and shiny. As we age, estrogen levels decline, which leads to graying of hair, which is the normal function of the human body. But is it a good thing or a bad thing that gray hair suddenly turns black?

An aunt's mother-in-law is 87 years old this year, and she has very beautiful white hair, and we all think that this old lady is very temperamental, and last year, her white hair began to change color. Her white hair turned yellow, and then black, and everyone said that she was a sign of a long life, but she herself said that it was not a good thing, and she might be sick ......The family was afraid that she would be cranky, so they took her to the doctor, and when they checked it, something really went wrongEstrogen levels have increased, and there must be a reason for this. Finally, the results of the examination showed that the old lady had cancer......It seems that the sudden turn of gray hair into black is not necessarily a good thing, and it must be treated with caution.

2. The sudden blackening of gray hair may be related to the kidneys

Before, there was a girl who started to have gray hair in her 20s, and she saw a Chinese medicine doctor and said that she had gray hair caused by bad kidneys. After conditioning, the girl took a lot of drugs that help the kidneys, so she gradually got better, her gray hair decreased, and her black hair gradually grew. If this old man's gray hair suddenly turns black, it may have something to do with the kidneys.

Abnormal growth may be a problem with the kidneys. Be sure to seek medical attention in time.

I am getting old, I am calm, a gray hair is a testimony of life experience, and a happy heart can accept my gray hair. So,Gray hair is a normal phenomenon, but gray hair turning black may have a big hidden danger, so you have to pay attention to it.

It may be that there is an imbalance in hormone secretion in the body, and it is recommended to go to the hospital for a check-up.

If there is gray hair but it turns black all of a sudden, it means that the body's hormones have undergone imbalanced changes, and then the body will have some sub-health at this time.

It may be that melanin synthesis has returned to normal.

It may be caused by endocrine disorders, or it may be related to the bad environment of life.

This is a manifestation of vigorous nutrition, so it is necessary to reduce protein intake and eat more to clear heat and cool blood.

Personally, I think it is caused by strong nutrition and then endocrine disorders.

The sudden darkening of gray hair indicates that the body is taking in too much nutrients, which will cause a certain amount of pressure on the metabolism of the kidneys.

Here's what's going on. Did anything different happen before it went black? It's dark, what's the condition?

It may be that you have been too tired and annoyed recently, so adjust yourself, if you want to get rid of it, eat more black sesame seeds, it is very useful.
