It is the number of pigment particles in hair that determines the color of hair, which is related to the development and growth of pigment cells in the papilla of hair roots. Hair turns from black to white. Generally speaking, the function of pigment cells in hair decreases. When it drops to the point where it can't produce pigment particles at all, the hair turns completely white. Normal people began to decline at the age of 35.
The prevention of white hair should pay attention to the following aspects: pay attention to diet and nutrition. Staple food can often eat beautyberry rice, black beans, red beans, mung beans, Hong Ling, black sesame seeds, walnuts and so on. Vegetables often eat carrots, spinach, purple radish heads, purple cabbage, mushrooms, black fungus and so on. Animals often eat black-bone chicken, beef, sheep, pig liver, soft-shelled turtle, dark fleshy fish, sea cucumber and so on. Fruits often eat jujube, black dates, persimmons, mulberries, purple grapes and so on. In short, all dark-colored foods (green, red, yellow and purple) contain pigments formed by the interaction between natural plants and sunlight, which can supplement the human body's pigments and be beneficial to the health care of hair color. In addition, pay attention to ensure adequate protein and vitamins. Eat more vegetable oil, less animal fat and less sugar. You can use a small amount of honey or brown sugar instead. Severe white hair should be treated in time, keep a good mood, and don't be overly nervous and tired.
