Gray Hair; Natural and/or Haircolor

Going grey is not associated with earlier mortality, and premature greying is not, generally speaking, a sign of a illness or ill health in younger adults. There are, however, some specific health conditions, such as vitiligo (an autoimmune disorder that causes uneven pigmentation) associated with grey or white hair, but for most of us, going grey is just a fact of life.

grey hairHair colour comes from the pigment melanin, which has two hues, blackish brown and reddish yellow—the amount and mix of each determines your individual shade. Hair without any melanin is pure white. The pigment is produced in cells called melanocytes, located at the base of the hair follicle. The melanocytes inject pigment into the hair. At some point in everyone’s lifetime, these cells slow down and eventually stop producing colour all together in what’s called apoptosis, or genetically predetermined demise. Scientists have yet to identify the exact mechanism by which melanocyte cell death occurs.
