What 'vitamin' does the human body lack to cause gray hair? How to prevent gray hair from appearing? After reading it, I have gained knowledge

With the improvement of living standards, from food and clothing to health, people began to pursue high-quality life. A nutritious diet is not only a change in eating habits, but also a change in concept.

Everyone hopes to have a good appearance and a good figure, but they also encounter many difficulties on this road, such as obesity, premature gray hair and so on.

Some are only two years old. They grow a lot of gray hair on their heads at the age of 30. For a long time, we have believed that only the elderly will have gray hair. Why do young people have gray hair? How can we turn gray hair into black except dyeing it?

Today, let's take a look at what causes gray hair and how to improve it.

Analysis: the cause of premature gray hair.

1. Excessive use of the brain.

Studies have found that mental workers have been in a state of high pressure for a long time, have high mental tension, have no time to think about exercise, and have an unbalanced diet and poor living habits, so they are prone to premature gray hair.

2. Lack of sleep.

Irregular life or lack of sleep can disrupt the autonomic nervous system. If growth hormone and systemic blood circulation are disturbed, the autonomic nerve will control the secretion of growth hormone, causing metabolism and blood circulation disorders, resulting in gray hair.

3. Suffering from chronic diseases.

Some people suffer from diseases such as autonomic dysfunction, hyperthyroidism, tuberculosis, typhoid fever, and endocrine disorders, which can also cause gray hair. This is because the disease destroys or interferes with the growth and development of papillae and hair bulb pigment cells, thereby losing the ability to secrete melanin and granules.

4. Genetic factors.

There are similar situations in parents or family blood, and juvenile gray hair also has certain congenital factors.

In addition, relevant studies have found that lack of vitamins in the body may also cause people to grow gray hair prematurely, so which vitamins are lacking before gray hair grows? Let's hear what the doctor has to say.

What vitamins does the body lack before gray hair grows?

folic acid

Everyone is familiar with folic acid. We all know that pregnant women often eat some folic acid in order to prevent neural tube defects in their newborns. Folic acid is called vitamin B9, vitamin M, and vitamin Bc, which belong to the vitamin B family. Folic acid can be used to treat folic acid deficiency caused by anemia. Folic acid is also a nutritional supplement for pregnant women.

More than half of neonatal neural tube defect cases are due to folic acid deficiency in early pregnancy. In order to reduce the proportion of neural tube defects, more than 50 countries use nutrient-fortified foods with added folic acid.

Long-term folic acid supplementation was associated with a slightly lower risk of stroke and cardiovascular disease. People who are deficient in folic acid for a long time are more likely to turn white than ordinary people, which may be due to the reduced production of melanin.

Vitamin B12.

Vitamin B12 is a complex organic compound containing cobalt and is one of the B vitamins. Vitamin B12 has the following functions: promote the formation and regeneration of red blood cells, and prevent anemia; it is mainly used to treat pernicious anemia and aplastic anemia, and is also used together with folic acid to treat various red blood cell anemias.

Maintain the normal function of the nervous system; used for nervous system diseases, such as neuritis, neurasthenia, depression, etc. Promotes concentration, improves memory and balance. Treatment of liver diseases such as hepatitis and cirrhosis. Promote children's development and increase appetite. People with vitamin B12 deficiency also have reduced melanin production.

The Fengchi point is located under the back of the skull, on the back of the neck, at the same height as the earlobe.

Extension - Is it true that white hair cannot be pulled out, and the more it is pulled out, the more it will be pulled out?

Nowadays, many young people have gray hair. Some folks believe that white hair grows ten times after pulling it out, and the more it is pulled out, the more it is pulled out. Some people think that after the white hair is pulled out, the white pigment will 'pollute' other black hair follicles, resulting in more white hairs pulled out. .

In this regard, experts said that there is no so-called white pigment in the body. You won't be pulling out more and more gray hairs. The growth of black hair mainly depends on the hair root formed by melanocytes.

As we age, the pigment cells at the root of the skin stop or reduce the production of melanin, which results in white hair. Experts say that normal hair is black because of melanin, and white hair is because of the absence of melanin.

In addition, it is not recommended to forcibly pull out gray hair. While plucked gray hair won't make it grow longer, it can damage the roots, especially if pulled too much, and can also lead to folliculitis.
