What is the natural process of greying?
With age, or after periods of stress, the production of natural pigments may be reduced but the hair’s already on the head will not be affected, but the new ones will. As hair fall out and are replaced the proportion that have the original pigmentation diminishes and the hair’s overall colour changes. It may become lighter. If no pigment is produced at all, then the new hair will be white. The proportion of white hair among the naturally coloured ones causes the hair to appear grey. It is not uncommon for young people to exhibit some grey hair – this does not necessarily mean that they will go grey or completely white, at an early age.
