Hair color is genetically controlled. Dark color hair contains brown-black melanin, blonde or red hair contains yellow-red melanin. With age the melanocytes produce less melanin. The gray hair is the result of decreased production of melanin/dying. White hair is due to the body has stopped production of melanin completely. Take a class on Anatomy and Physiology and you can learn this and lots more interesting fun things about the body.

Grey hair does not exist!! Its an optical illusion. When melanin is not present, hair is then left white. Its the hair left with pigment that reflects into the (white) hair and you see grey. Reds and blondes will have a much lighter appearing grey tone than dark brown, which looks like gunmetal grey.
