The change in hair color is caused by the gradual decrease of pigmentation that occurs when melanin ceases to be produced in the hair root, and new hairs grow in without pigment. Two genes appear to be responsible for the process of greying, Bcl2 and Mitf. The stem cells at the base of hair follicles are responsible for producing melanocytes, the cells that produce and store pigment in hair and skin. The death of the melanocyte stem cells causes hair to begin going grey.
And also stress LOL!

My natural color is light brown. Even though I'm 70 years old and the top of my hair is what I prefer to call silver-the underneath hair in the back is still brown. It starting turning grey around the ears and widow's peak-then it went haywire. I think that's why hair dye was invented. We dont have to go grey until we want to.

Essentially, your hair no longer has the pigmentation necessary to make your hair a true color. At the root of the hair follicle, the stem doesn't produce melanin that “dyes” your hair a color.
This can be genetic or related to your age and smoking has been shown to prematurely grey hair as well.
Hope that helps.

Marriage. I started going grey soon after getting married. Whether this was coincidence or not I don't know.

As we breathe we break air down into various by products which include free radicals. These particals break down our DNA over time and as we get older it affects our ability to generate proteins, such as hair, nails and skin tissue, etc.
