5- Some research has suggested a connection between premature graying and lower bone density later in life. However, a 2007 study of about 1,200 men and women in california showed this not to be the case.“Your level of bone density is all related to activity level, your weight, your height, your ethnicity.

However, it is much too expensive with potentially severe and deadly side effects to be used to alter a person's hair color. Nevertheless, if the mechanism of action of Imatinib on melanocyte stem cells can be discovered, it is possible that a safer and less expensive substitute drug might someday be developed.
2-Eating of foods rich in iron, vitamin B, sodium, and copper . Fruits and vegetables contain antioxidants that fight against free radicals which can cause premature white hair.
3- Massage hair with coconut oil that is boiled with curry leaves.

8- The vitamins considered useful in guarding against premature greying of hair are pantothenic acid, para-aminobenzoic acid (paba), inositol. The minimum daily requirement of these vitamins appears to be 10 mg of pantothenic acid, 100 mg of para-aminobenzoic acid, and 2 gm of inositol. To obtain satisfactory results, all three of these vitamins belonging to the B group should be supplied at one time, preferably in a form which supplies all the B vitamins, such as yeast and liver. The three anti-greying-hair vitamins can also be produced in the intestinal tract by bacteria.
