Ten-year-old boy has white hair

1. Reasons why children have white hair

1. Genetic factors: Professor Wang Xuemin, director of the Municipal Hospital for Dermatology and Venereology, pointed out that from a clinical perspective, the vast majority of "premature graying of hair" patients have a genetic background. Some patients will have gray hair when they reach a certain age, and there are also people who are born with gray hair.

2. Mental factors: Premature gray hair is caused by the synthesis disorder of melanin particles in the hair. It does not affect your health. The most direct cause of premature gray hair is mental factors, such as excessive worry, panic, fright and excessive mental fatigue. High mental tension causes spasm of capillaries that supply nutrients, which causes disorder of melanin secretion and affects the synthesis and transport of pigment particles.

3. Nutritional factors: such as lack of vitamins, trace elements, etc.

4. White hair can also grow due to nerve trauma, protein deficiency, severe malnutrition, etc. Premature graying of hair may also be a precursor to diseases such as autonomic dysfunction and hyperthyroidism. Because the pathogenic factors destroy or interfere with the growth and development of pigment cells in the hair follicles, causing them to lose the ability to secrete melanin and hindering the formation of pigment particles.

2. Methods for preventing and treating gray hair

In order to prevent the premature appearance of premature gray hair, you should pay attention to consuming more foods rich in iron and copper in your diet. Foods rich in iron include animal liver, eggs, black fungus, kelp, soybeans, sesame paste, etc.; foods rich in copper include animal liver, kidneys, shrimps and crabs, nuts, dried apricots and dried beans, etc. Pay attention to the intake of B vitamins. Lack of vitamins B1, B2, and B6 is also an important cause of premature graying of hair. The intake of such foods should be increased, such as cereals, beans, dried fruits, animal liver, heart, kidney, milk, eggs and leafy vegetables. Also pay attention to eating more foods rich in tyrosine. The formation process of melanin is from the oxidation of tyrosine by tyrosinase. That is, the basis for the formation of melanin is tyrosine, and tyrosine deficiency can also cause premature graying of hair. Therefore, you should consume more foods rich in tyrosine, such as chicken, lean beef, lean pork, rabbit meat, fish and nuts. In addition, regularly eat foods that are beneficial to hair care and blackening, and increase the raw materials for synthesizing melanin. Traditional Chinese medicine believes that "hair is the residue of blood" and "kidneys control bones, and their smoothness is in the hair" and advocates eating more foods that nourish blood and kidney to blacken and moisturize hair.
