Gray Hair

-Each hair follicle contains a certain number of pigment cells. These pigment cells continuously produce a chemical called melanin
-Melanin gives the growing hair shaft its color
-As we get older the pigment cells in our hair follicles gradually die
-The hair will no longer contain much melanin causing the hair to be transparent
-Eventually the hair will turn completely grey
-People can get grey hair at any age, it is determined by our genes
