Nowadays, we often see some young people with gray hair that doesn't match their age. Some beauty lovers have to worry about snow dyed green silk. What is the cause of premature hair whitening? In fact, such as heredity, mental stress, sun exposure, lack of nutrients and so on, can promote the early birth of white hair.

What nutrition does white hair lack

First: the long-term intake of protein is insufficient. Melanin is indispensable for the black hair of Oriental people. It is the dark brown pigment that commonly exists in the skin and hair. It is precisely because of it that our skin and hair have color. Melanin is actually a kind of protein. 20-25 years old is an active period for the formation of melanin precipitation. People at this age should not have white hair. If they have white hair at a young age, it is likely that the lack of protein intake in the diet for a long time leads to insufficient melanin synthesis.

Second: Although the copper in our body stock is small, but can not be missing. Without copper, more than 30 enzymes in the body will lose their activity, and normal functions such as bones, skin and hair will also be affected. Through the determination of trace elements in hair, it is found that the copper element in dark hair is significantly more than that in light hair. For example, the copper element in black hair is higher than that in yellow hair, and the copper element in yellow hair is higher than that in white hair. The copper element in female hair is higher than that in male hair. Therefore, the lack of copper is also one of the important reasons for the early white hair of young and middle-aged people.

Third: the study found that people eat too much salt, will cause insufficient blood supply to the head, leading to a decline in the ability to synthesize melanin, melanin cells can not be successfully synthesized, easy to produce less white head. Therefore, the reason why the white haired girl's hair turns white is definitely not caused by lack of salt, but more by the comprehensive factors such as Yang Bailao's various kinds of devastation and torture, excessive mental pressure and so on.
