Is yellow hair a sign of kidney yin deficiency?

Dry, frizzy and yellow hair is not necessarily caused by kidney deficiency. It may be caused by some diseases, such as iron deficiency anemia and the initial recovery from illness, which can cause the hair to turn from black to yellow. Malnutrition, excessive acidity and alkalinity in the blood, and copper deficiency can all cause hair to turn yellow.

Dry, frizzy and yellow hair is not necessarily caused by kidney deficiency. It may be caused by some diseases, such as iron deficiency anemia and the initial recovery from illness, which can turn black hair from black to yellow. In this case, you should eat more black beans, walnuts, fennel, etc. Black beans contain pigment reactants that promote the production of melanin. The anisole in fennel helps to transform chromogens into melanocytes, thereby making the hair darker, softer and brighter. The key causes of dry, frizzy and yellow hair are: low thyroid hormone; high-width malnutrition; moderate to severe iron deficiency anemia and initial recovery from illness, which cause the body's pigment to decrease, resulting in a lack of the basic substances for dark hair, and the black hair gradually turns into brown or light yellow.

In addition, frequent perming, washing hair with edible alkali or soap powder will also damage the hair and turn it yellow. The following are the dietary treatments for several types of gray hair caused by pathogenic factors. The first is malnutrition-related gray hair. This condition is mainly caused by high-aspect malnutrition. You should pay attention to the preparation of diet and improve the nutritional composition of the human body.

Second, acidic body causes yellow hair. It is related to the increase of acidic and alkaline toxins in the blood, as well as overwork, overeating of sweets and body fat. You should eat more kelp, fish, fresh milk, bean products, mushrooms, etc. In addition, eating more fresh fruits and vegetables, such as asparagus, rapeseed, broccoli, green vegetables, citrus, etc., is beneficial to neutralize the body's acidic and alkaline toxins and improve the yellowing situation. Third, copper deficiency causes yellow hair. In the whole process of hair conversion into pigment, a key copper-containing "tyrosinase" is lacking. Copper deficiency in the body will affect the activity of this enzyme, causing the hair to turn yellow.
