White is the true color of our hair. The pigment cells located at the base of each hair follicle are the ones that provide the dominant natural color of our hair in youth.
As the individual grows closer to maturity, more and more of these pigment cells die and the color begins to fade. The result is gray hair.
It can take between 10 and 20 years, depending on how much hair you have, for a person to become a ''white head''. It is interesting to know that, before dying, pigment cells quickly produce large amounts of ''color'' so that the hair temporarily darkens before turning white (or gray) forever.
