What are the causes of localized graying of hair and why does hair turn gray

Traditional Chinese medicine theory believes that "the kidney is the main bone and marrow, and its splendor is in the hair", "the liver hides blood" and "the hair is the rest of the blood", when the liver and kidney are insufficient, the essence and blood are deficient, and the hair loses its inner nourishment and turns white.

Gray hair is usually caused by physiological causes, such as age, family genetics, emotional stress, poor diet, etc., which may lead to different degrees of gray hair, and it is recommended to effectively improve the cause.

Factors that make hair gray

1. Emotional stress factors:Being too nervous and anxious and unable to relax one's mind may affect blood circulation, resulting in less melanocyte formation, gray hair, and even overnight whiteness, usually not accompanied by other clinical symptoms. It is necessary to maintain an optimistic and positive attitude, and when the mood is relieved, the symptoms of gray hair will also be improved.

2. Familial genetic factors:The graying of hair at a young age may be related to family genetics, which can lead to premature decline of melanocytes in the hair follicles, causing the hair to gradually turn gray, and generally does not cause other uncomfortable symptoms. It is necessary to pay attention to keeping the hair area clean and hygienic, and also need to maintain enough sleep to reduce the phenomenon of melanocyte decline.

3. Factors for increasing age:As we age, the function of melanocytes in the body usually declines, and pigment secretion gradually decreases or even stops secreting, which may lead to gradual graying of hair without obvious discomfort symptoms. It is generally a normal physiological condition and does not need to be accepted**.

4. Malnutrition factors:If you don't pay attention to a reasonable diet and don't pay attention to the intake of nutrients for a long time, it will lead to hair follicle melanocyte synthesis disorders, gray hair, fatigue, lack of energy and other manifestations. It is necessary to adjust the diet structure in time and eat more melanin-containing foods such as black beans and black sesame seeds to alleviate it.

The number of melanin-producing cells in the body decreases to some extent, resulting in graying of the hair.

Due to the aging of the body and the decline of physical ability, the time of gray hair will be different for each person, and the occurrence of gray hair in young people is usually directly related to genetic factors or acquired stress. It is difficult to have gray hair caused by congenital inheritance, but gray hair caused by acquired causes can be improved after **. Malnutrition is one of the causes of gray hair, which is an appendage of the first and needs adequate nutrients to grow.

If picky and picky eating habits persist for a long time, nutrient intake may be insufficient, and hair is prone to lack of protein and various vitamins, resulting in a change from black to white. You should pay more attention to rest and strengthen nutrition.

Misconceptions about gray hair:

For gray hair, some people dispose of it by growing one and pulling it out. There is a folk saying: white hair cannot be plucked casually, and if you pluck one, you will grow three. In fact, there is no scientific basis for this claim.

The color of black hair mainly depends on the melanocytes at the root of the hair. As we age, the pigment cells at the root of the hair follicles will gradually stop producing melanin, which is why gray hair is formed. Although forcibly plucking gray hair does not make it grow more and more, it can damage the hair roots, especially if you pull it out too much, it may also cause folliculitis.

Worrying, overusing the brain, and too much stress can cause gray hair to grow.
