Walnut is a very nutritious nut, rich in protein, fat, fiber and a variety of vitamins and minerals. Fresh walnuts and dried walnuts have slightly different nutritional profiles. Fresh walnuts have a high water content, so they contain relatively more vitamin C and other water-soluble vitamins. Dried walnuts, on the other hand, have more concentrated nutrients such as protein, fat, B vitamins and minerals because the water has been removed. So from this perspective, dried walnuts may be richer in some nutrients.

As for whether eating walnuts can turn white hair into black hair, there is currently no clear evidence in scientific research to support this statement. The formation of gray hair is related to many factors, including genetics, age, stress, etc. Although walnuts are rich in certain nutrients, it is not realistic to simply rely on eating walnuts to change hair color. If your hair turns gray, it is recommended to find other effective conditioning methods, such as maintaining good living habits, eating a reasonable diet, exercising moderately, etc.

Fresh walnuts and dried walnuts are very nutritious foods that have many benefits for human health. If you want to get more vitamin C, you can choose fresh walnuts; if you want more protein, fat and vitamin B, you can choose dried walnuts. But no matter what kind of walnut it is, eating it alone cannot change your hair color. If you have hair problems, it is recommended to seek the advice of a professional doctor or hairdresser and adopt scientific and effective conditioning methods. Remember, maintaining healthy lifestyle habits is the key to healthy hair.
