Achromotrichia is defined as the absence or loss of pigmentation in the hair. The good and bad news (depending on how you look at it) is that greying hair is very much a normal process of ageing and unfortunately can really happen at any age. Greying is almost entirely due to genetics. If your parents and/or grandparents started going grey early, chances are, you may also.
Why we Grey?
Stem cells at the base of the hair follicle produce melanocytes (which are the cells that produce and store pigment/colour). As we age, melanocytes become inactive and eventually decrease in number until they are gone altogether. The decrease of melanocytes means greying of hair, the disappearance leads to white hair. In this sense, greying or whitening of the hair is not a change in colour, but rather a lack of pigment in the hair altogether.
Conditions that may cause us to go Grey
Vitiligois a condition is which there is patchy losses of hair and skin colour. This is due to an autoimmune condition. Rare conditions such as Neurofibromatosis and Tuberous sclerosis have also been associated with greying or whitening of the hair, as have some more common conditions, such as B12 deficiency or hypothyroid conditions.
