The color of our hair is black because there is melanin. When cells that produce melanin age, they can't produce melanin, but they will produce white hair, so aging has a great influence on cells, which is why we often say that white hair is a symbol of aging. In addition to aging, more and more people have the phenomenon of juvenile white hair. How can we improve the problem of white hair through diet?

In addition to the problem of white hair caused by aging, some studies have confirmed that the increase of oxidative stress can easily lead to adolescent white hair, such as stress, drinking, obesity and so on. In addition, family inheritance or a history of congenital chronic diseases in the family may be the factors affecting hair whitening.

In fact, the color of hair is also closely related to nutrient intake. A study in July, 2065438 in India analyzed the records of patients who received treatment for juvenile white hair in the past five years, and found that juvenile white hair was closely related to vitamin B 12 deficiency and thyroid dysfunction. Therefore, the intake of foods rich in iodine and vitamin B 12 may help to reduce the phenomenon of juvenile gray hair.
