Is Grey Hair Hereditary

Kacee: My name is Kacee. I'm from Turtle grove, California. My grandfather is well into his 70's and he doesn't have a gray hair on his head. Does that mean as I age, I won't get any gray hairs?

Joseph Greco: No Kacee, unfortunately it doesn't mean that you won't get any gray hair, but you might be -- because genetics does play a very important role. Especially, with regards to the age of onset of the gray hair. So, you might not ran to later, but you do need to look at other family members, not just your grandfather. Now, graying of the hair results from a gradual decrease in the production of hair pigment until at some point, really very little or no pigment is produced at all. And the progression of that hair graying is going to be entirely individual. But a good rule of thumb is that by the age of 50, 50% of people will have 50% gray hair.
