Modern medicine believes that the occurrence of less white head is mostly related to neurological factors, nutritional deficiencies, endocrine disorders and systemic chronic wasting diseases.

Chinese medicine, on the other hand, believes that this disease is mainly due to insufficiency of the liver and kidney, qi and blood loss. The congenital less white head is mostly related to heredity, it is not easy to treat; while the acquired less white head, in addition to the treatment according to the cause of the disease, should strengthen the nutrition. Experiments have shown that the lack of protein and a high degree of malnutrition is one of the causes of early gray hair. Dietary deficiency of trace elements such as copper, cobalt and iron can also lead to gray hair.

In order to prevent the premature appearance of whiteheads, in the diet should pay attention to more intake of iron and copper food. Iron-containing foods are animal liver, eggs, black fungus, kelp, soybeans, sesame paste, etc.; copper-containing foods are animal liver, kidneys, shrimps and crabs, hard fruits, apricot pavement dry and dry beans. Pay attention to the intake of B vitamins. Medical doctors have now confirmed that the lack of vitamin B1, B2, B6 is also an important cause of less white head. Should increase the intake of such foods, such as cereals, beans, dried fruits, animal liver, heart, kidney, dairy, eggs and leafy vegetables. Attention should also be paid to more intake of tyrosine-rich foods. The process of melanin formation is oxidized tyrosine by tyrosine mold. In other words, the basis of melanin formation is tyrosine, tyrosine deficiency will also cause less white head. Therefore, should be more intake of tyrosine-rich foods, such as chicken, lean beef, lean pork, rabbit, fish and hard fruit foods.

In addition, often eat some of the food is good for hair, increase the synthesis of melanin raw materials. Traditional Chinese medicine believes that "hair for the blood of the Yu", "the main bone of the kidneys, its smooth in the hair", and advocate eating more blood to tonify the kidneys of the food in order to hair moisturizing.
