What is the reason why there are more and more white hair? What do you eat with white hair

4hw.com.cn: now, with the increasing pressure of people's life, the psychological pressure is also increasing, and there are more and more people with white hair. In addition to age factors, there are also psychological, disease, environment and other factors. Let's take a look at the reasons for long white hair. What should we do if there are more and more white hair?

When the cells that produce our hair pigment become too damaged, the next growing hair is gray. During hair growth, melanocytes make pigment and transfer it to precursor cells at the bottom of hair follicles. In turn, these cells convert into various components of growing hair.

As our hair grows, pigments are constantly combined, which leads to our unique hair color. The cells responsible for this process are melanocytes that produce pigment at the bottom of hair follicles.

In normal hair growth, hair follicles produce hair at a rate of about 1 cm per month for several years.

But in our lifetime, all cells in our body will be more and more damaged, and these melanocytes will eventually be lost. When all melanocytes disappear into a specific hair follicle, the next hair turns gray or white.

The biology of hair growth is quite complex. There are many specialized cells involved in the structure and function of hair follicles. Scientists continue to unravel the process of human hair growth and pigmentation.

What controls pigmentation?

Humans have two different pigments. Omelanin is responsible for black and brown, while ephedrine is responsible for orange and yellow.

Genes determine the mixing of pigments produced by each individual, which is why hair color is often similar in families.

The exact mechanism controlling pigmentation is unclear. However, recent studies refer to fine-tuning interactions between several cells in hair follicles.

It is reported that hair progenitor cells release a type of pigment called stem cells, which is necessary for melanocytes to produce pigment. In the mouse study, the researchers showed that if the protein was not present, the hair color would disappear.

How to do with more and more white hair?

White hair is mainly due to the reduction of melanin particles in the hair medulla and cortex or filled with air. White hair will appear when the formation of melanin particles in the hair mastoid head and hair bulb is blocked, or although they are formed, they cannot be transported to the hair due to some factors, resulting in the reduction and disappearance of melanin particles in the hair medulla and cortex.

1. Psychological factors

When people are in the psychological state of anxiety, tension and depression for a long time, the blood circulation and internal environment of the brain will be damaged to a certain extent, resulting in headache, dizziness, long white hair and so on.

2. Poor nutritional status

If the diet is short of copper, cobalt, iron, protein, vegetable oil, vitamin B1, vitamin B2 and vitamin B6 for a long time, the hair will turn from black to white.

Once the hair stops growing, the hair follicle will undergo drastic structural changes and enter the rest period. In this process, melanocytes die naturally.

However, melanocyte stem cells in hair follicles usually produce a new melanocyte at the beginning of the next hair growth cycle.

Once new hair begins to grow, these melanocytes again ensure that pigmentation is available. However, when melanocytes are damaged or missing, the resulting hair lacks color and may look gray or white.

Hair growth after injury

Studies have shown that human hair follicles that produce gray or white hair have a high level of free radicals caused by cell damage. In these follicles, melanocytes and melanocyte stem cells are missing.

In mice, when the DNA of melanocytes and stem cells in hair follicles is damaged, permanent cell damage is caused. These stem cells then fail to reproduce.

In the absence of stem cell pool, there are no melanocytes in the next round of hair growth, resulting in gray hair.

Although the cause and effect have not been completely determined in the process of human hair whitening, the damage and accumulation of melanocyte stem cells are likely to reduce the number of such cells over time. Each hair follicle will eventually fail to produce colored hair.

Therefore, although it is inevitable that one day we will all lose our hair pigment, why do some of us become gray in our 20s, while others will keep colorful hair until their 50s? The 2018 results show that individuals carrying interferon regulatory factor 4 are prone to early-onset whitening.

White hair diet prescription

3. Immortal porridge, Polygonum multiflorum 30 ~ 60g, 5 red dates, 10g brown sugar and 60g japonica rice.

First put Polygonum multiflorum into a small casserole, fry the juice, remove the residue, put in the washed japonica rice and red dates, add an appropriate amount of water to cook porridge, and add brown sugar after the porridge is cooked. This porridge has the functions of nourishing blood and liver, consolidating essence and tonifying kidney and blackening hair. It is suitable for people with early white hair and yellow hair.
