Premature greying is sometimes caused by environmental and underling health factors such as diet.

Consuming excessive amount of foods with excessive amounts of iodine can increase the risk of developing thyroid complications such as hitches.

Hitches have an impact on the hair’s health thus causing premature greying. Also smoking cigarettes can cause premature greying.

Tobacco can also affect the hair follicle cells thus the early greying. Anemia due vitamin B12 deficiency causes the body to lose melanocytes.

Drug dependence due to chronic ailments such as AIDS/HIV, cancer and thyroid imbalance is well documented to be the main trigger for premature greying. This is because they destabilize hormones that in turn affect the body cells, which have an effect on hair follicles.
