What s the deal with the gray hair on your head? What is the cause of gray hair on the hair

Reasons for gray hair on the head:

1.Normal physiological phenomena:

As we age, various organs in the body gradually deteriorate, which may lead to insufficient melanin synthesis in the hair, resulting in gray hair on the head. This is usually normal.

2.Genetic factors:

Due to genetic factors, the congenital lack of certain nutrients in the body or the absorption of certain nutrients can lead to gray hairs on the head.

3.The body lacks some nutrients:

The lack of vitamins, trace elements, minerals and other substances in the body will cause a lack of nutrients in the hair, resulting in yellow hair and even gray hair.

4.Excessive use of the brain:

Excessive use of the brain usually causes the intracranial pressure of the head to be in a state of high pressure for a long time, which will lead to a decrease in the function of the body, which will cause the appearance of gray hair.

The black color of hair is formed by the synthesis of melanin by the black cells inside the hair follicle, and gray hair may occur if certain factors interfere with the function of the melanocytes of the hair follicle or reduce the number of melanocytes in the hair follicle. The common reasons are as follows: 1. Hereditary gray hair, patients often have a family history, parents have less white hair, and children may also have early gray hair, which may be caused by hereditary reasons, the premature decline of the function of the patient's hair follicle melanocytes, and the disappearance of function.

Second, natural senile gray hair, with age, the function of melanocytes in hair follicles will also decline, and gray hair will appear. Third, it is more common to have gray hair caused by mental factors, as the saying goes, if you are sad, you will have a gray head. This suggests that mental stress, anxiety, irritability, and can also have a noticeable effect on follicular melanocytes, leading to their dysfunction and the production of gray hair.

Fourth, there are nutritional factors, such as iron, zinc, copper, lack of some vitamins and trace elements, so that the hair follicle melanocytes can not get sufficient nutrients**, and it is difficult to form melanin, and gray hair appears.

The tyrosinase activity of melanocytes in the hair follicles decreases or is lost, resulting in the gradual loss of pigment from the hair that grows in the hair follicles, resulting in the gradual appearance of gray hair. If it is senile gray hair, it is a normal physiological phenomenon. There are also some pathological factors that can cause the decline and loss of melanocyte tyrosinase activity, among which genetic factors play a great role, and other factors such as excessive stress, fatigue, emotional agitation, and malnutrition are also very important factors.

In modern society, the fast pace of life, irregular work and rest, and high mental pressure are all causes of gray hair.

Causes of gray hair on the top of the head: 1. The manifestation of body aging is a normal physiological phenomenon, with the increase of age, the activity of melanocytes in the hair follicles decreases, so that the production of melanin decreases or disappears, resulting in the appearance of gray hair on the top of the head. Usually eat more foods with high melanin content, massage the scalp on the top of the head with your fingertips, promote local blood circulation, and reduce gray hair.

Second, the immediate family members have white hair on the top of the head, considering that it is caused by chromosomal dominant inheritance, there is no good way to do this, you can use a horn comb to gently comb your hair to promote blood circulation to improve the symptoms. 3. Mental stress, staying up late for a long time, lack of copper and iron, affecting melanin synthesis and resulting in gray hair, to maintain a good attitude, change the work and rest time, eat more black fungus, animal liver, nuts and other foods with more copper and iron content, the symptoms can be improved.

There is gray hair in the hair because the tyrosinase activity of melanocytes in the hair follicles decreases or is lost, resulting in the gradual disappearance of the pigment of the hair growing in the hair follicles, and there are also genetic factors.

What is the reason for gray hair on the hair, I think it is related to the pressure of life, as well as the imbalance of various vitamins in oneself, irregular work and rest time, staying up late, etc., and it is necessary to pay attention to changing bad habits and bad habits, and you can get better.

Since the pigment particles in the hair are a mixture of iron, copper, and cobalt, people with gray hair should eat more in their daily life.

Some foods that contain a lot of these elements such as rape, celery, kelp, soybeans, seaweed, pork liver, chicken liver, longan, black fungus, etc.
