Graying and Dandruff: Going gray, by itself, does not mean you have a medical problem, except in rare cases. Scientists don’t know exactly why some people go gray early, but genes play a large role. Also, a vitamin B-12 deficiency or problems with your pituitary or thyroid gland can cause premature graying that’s reversible if the problem is corrected. Dandruff is easily treated with medicated shampoos. Best wishes
