Insufficient zinc, copper, iron and other trace elements in the body or too much lead in the blood will lead to gray hair. Hair dyeing can also lead to white hair. Stress, mental anxiety or sadness can also accelerate the whitening of black hair.
High malnutrition is also one of the reasons for premature gray hair. You can eat more eggs, black fungus, kelp, soybeans, nuts and so on.
Lack of vitamins B 1, B2 and B6 can also lead to baldness, which requires more foods rich in B vitamins, such as cereals, beans, milk, eggs and green leafy vegetables.
Traditional Chinese medicine believes that blood heat, qi and blood weakness, spleen deficiency and kidney deficiency are all causes of white hair.
Adjust the diet structure, don't be partial to food, eat more beans and vegetables. Animal viscera contains more copper, such as persimmons, tomatoes, potatoes, spinach, etc., and also contains a certain amount of trace elements such as copper and iron, which are indispensable raw materials for melanin synthesis. Try to eat as much as possible.
In the social environment, young people should learn the methods of mental health care and self-regulation. In other words, we should not only be able to work and study, but also be able to play and adjust, pay attention to the combination of work and rest, keep a good mood and avoid excessive mental stress. Psychological peace is very important to prevent premature gray hair.
Extended information: the difference between young white hair and natural white hair;
These two parts are different. Teenagers' white hair grows on the top of their heads, pillows and hairlines, while middle-aged and elderly people start from the temples and then spread to the whole head.
Teenagers' white hair is often related to genetic, mental and dietary factors, while the generation of old people's white hair is a synchronous aging process with other tissues and organs of the body.
On the one hand, the number of hair mother melanocytes in scalp hair follicles of the elderly gradually decreases;
On the other hand, the synthesis of melanin needs the catalysis of tyrosinase. Although tyrosinase still appears as usual in the elderly, its activity is already very low, and it cannot produce melanin vigorously, so the hair gradually turns white.
Therefore, if adolescent white hair is caused by mental and dietary factors, it may be reversed after treatment for the cause. It is unlikely that the old man's white hair will turn black.
