BAThe article discusses a study linking deficiencies in certain vitamins and minerals to premature graying of hair. It highlights that while genetics still play a role, diet has a more significant impact than previously thought. Vitamin B12 deficiency was most commonly associated with early graying, with individuals experiencing this condition showing significantly lower serum levels of the vitamin compared to those whose hair did not gray prematurely. The research also noted a connection between pernicious anemia—a condition affecting vitamin B12 absorption—and early graying, with around 55% of affected individuals experiencing premature graying before age 50. Lower levels of vitamin D, calcium, and copper were also observed among those with early graying. While genetic predisposition was acknowledged, researchers emphasized that the cause is multifactorial, involving both inheritance and dietary factors. Other potential contributors include oxidative stress, autoimmune diseases, thyroid issues, and smoking.
