How is gray hairs formed?
When every human is born their hair creating cells are "programmed" to include a certain color of pigment into new hair cells, which are naturally white. However, as a person ages, the pigment producing cells start to disintegrate, consequently, creating in less and less pigment to incorporate into newly produced hair (hair grows 100 nanometers every second). This results in hair color decreasing from a vibrant red or brown to gray. Lighter color hair, such as blonde, will loose all of its pigment, resulting in white hair.
