please give the solution to reverse the gray hair on head & face.Also give details which vitamin deficiency causes the gray hair.
Going gray, by itself, does not mean you have a medical problem, except in rare cases.
Contrary to popular belief, stress has not been shown to cause gray hair. 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.
Some research has suggested a connection between premature graying and lower bone density later in life. But in 2007, a study of about 1,200 California men and women showed no such link.
Have an examination by your physician for vitamin deficiency or other organic problems. Otherwise, get an over the counter solution and color that gray hair!
