Most Asians have brown and black hair because the pigment particles in their hair contain copper, cobalt and iron. If the diet lacks these inorganic salts for a long time, it will affect the synthesis of melanin and make the hair turn from black to white.

White hair is divided into early white hair and old white hair.
Early white hair is premature white hair, which is also called "juvenile white hair" among the people. It is common in young people and even children, and it is pathological and mostly autosomal dominant inheritance.
