There are many reasons for hair loss, and improper diet can also be one of the causes. Research has shown that eating too salty or too sweet food not only causes nutritional and metabolic hair loss, but can also make hair become dry and yellow.
Salt can cause excessive water retention in the hair, affecting its normal growth and development. At the same time, excessive salt in the hair provides a good environment for bacterial growth, which can easily lead to scalp diseases. Too much salt can also induce various seborrheic diseases, increase the amount of dandruff, and worsen hair loss. A diet that is too salty can also burden the kidneys, further causing sodium excretion disorders, which can lead to high blood pressure, protein metabolism disorders, affect the formation of protein in the hair, and cause the hair's color to fade or even become withered. Excessive sugar intake can also cause hair loss. Excessive sugar in the body's metabolic process forms a large amount of organic acid, disrupting the hair's pigment metabolism, causing the hair to gradually lose its luster and become dry and yellow.
People who often lose hair are often deficient in iron. Foods rich in iron include soybeans, black beans, eggs, hairtail, shrimp, carp, spinach, bananas, carrots, potatoes, etc. You can appropriately eat more coarse grains, beans, peanuts, green vegetables, and melons and fruits that are rich in vitamins. If the hair is dry and the ends are split, you can eat more soybeans, black sesame, and corn. The luster of the hair is related to the function of the thyroid gland. Supplementing with iodine can enhance the secretory function of the thyroid gland, which is beneficial for healthy and beautiful hair. You can eat more foods such as kelp, seaweed, and oysters.
