People usually associate gray hair with aging. Most people have the mentality that only gray hair should be seen on old people. Even though this is true, gray hair can also be spotted on people who are young; perhaps in their early twenties. The reasons for premature graying of hair are numerous. However, experts believe that graying of hair is caused by naturally occurring hydrogen peroxide on the hair. When it builds up in the hair, it eventually causes discoloration. Another reason could be when hair cells that give hair its natural pigment, die off
It is estimated that white people start graying in their mid-thirties while Asians in their late thirties. African Americans on the other hand begin to see gray hair in their mid-40s. Generally, most people begin to see gray hair by the time they turn 50. Any African American who starts experiencing gray hair in their twenties is said to be prematurely graying. The same concept applies to all the other races.
