Premature graying of hair. How to prevent it from spreading

In the hair root area, there are cells that produce pigment. Asians have black or dark brown hair because they have a pigment called ‘eumelanin’ , which is a dark color. But people with blonde hair have less eumelanin and will have lighter pigment cells called ‘pheomelanin’.
These pigment cells are like other cells in the body that will deteriorate, work more slowly, or die, and new cells are created to replace them.
