Many people may have experienced such an experience

When looking at the mirror

I found a few white hair

And the location is obvious

I just want to pull off my white hair

But the family does not let

There is a saying

People with more white hair are not easy to get cancer

Is that really the case?

Is the increase in white hair because of getting old?

Let's look at it together ~

1

People with more white hair are not easy to get cancer?

Not logical.

The various parts of the body actually have melanocytes, and the causes of evil changes are also complicated, so the formation of white hair is more complicated. There is no so -called white -headed hair. Essence

Why president white hair?

Human white hair is related to age, and it is also related to some other physical factors. We need to look at why hair turns white.

Tyrtinase is a coat -rich cell, which is the cause of black hair. With aging, the activity of tyrosinase will be reduced. At the same time, melanocytes are reduced, and the hair will turn white, so the gray hair is a normal aging phenomenon.

However, there are also some people's hair early, which is related to the inheritance, genes, mental factors, and tyrosinase, and even some chronic consumed diseases.

In the "Nature" magazine in January 2020, the impact of different pressure on mice with black mice as the experimental model was used as the experimental model.

Studies have found that stress can cause sympathetic nerve to release norepinephrine. This substance is absorbed by nearby pigment regeneration stem cells, causing excessive activation of stem cells. All stem cells are converted into cells that produce pigments. Essence Once all stem cells that can regenerate the pigment disappear, it cannot be reappeared into pigment. This damage is permanent. In the diner, the norepinephrine can also promote the proliferation of melanocytes of melanocytes, which also means that human hair becomes white under pressure, and it may also be the same physiological mechanism.

Can white hair still turn black?

If the hair has been clearly white, it is difficult to turn white hair into black hair, because the color stem cells of the hair follicles have been exhausted, and it is difficult to reverse.

If you find white hair, you can analyze the cause first, whether it is in line with aging laws, whether the pressure has been too great recently, or a problem with diet.

Why does white hair suddenly increase?

The sudden increase in white hair may be these four nutrients in the body.

1. Trace element copper and iron: important raw materials for synthetic melanin

The hair follicles of the hair need to absorb the iron and copper elements in the human body to synthesize melanin. This substance can make people's hair dark and bright, and it looks young. However, when these two trace elements are lacking, the nickel content in the hair will increase a lot, and the color of the hair will change from black to white.

Supplementary ways: black fungus, animal liver, red meat, sesame, nuts and other foods.

2. Protein: raw materials for hair

Compared with the former, the problem of lack of protein is more likely to make people with white hair and hair loss.

You must know that protein is one of the main raw materials for hair, which can help the human body synthesize sufficient keratin. If people are picky for a long time, they are likely to make the human body lack protein, and it is more prone to malnutrition and other problems.

This kind of population will not only appear white hair due to malnutrition, but also may have the problem of yellowing, splitting, dryness, or even hair loss because the protein in the human body cannot maintain the growth of hair.

Supplementary channels: eggs, milk, fish, beef, etc.

3. iodine element: promote hair growth

As the essential nutrients of the thyroid maintenance function, iodine can also promote the growth of hair.

Some people may have a decrease in hair follicle function due to iodine deficiency. Even if there is sufficient nutritional supply, it cannot synthesize melanin for the human body, maintaining black hair, and the hair may suddenly turn white.

Supplementary channels: iodine salt, seaweed, kelp, etc.

4. Vitamin B family: important metabolic substances

Among the vitamins B, B2, B3, and B5 are nutrients that are greatly helpful for improving white hair.

When the human body is long -term vegetarian, or is affected by diabetes, hypoglycemic drugs, etc., it may cause the hair to suddenly turn white.

Supplementary channels: It is recommended to improve white hair by supplementing vitamin B. Make up vitamin B, focusing on a balanced diet. Vitamin B has a high content in whole grains, green leaf vegetables, dairy products and animal liver.
