B complex vitamins such as B12, Biotin, and B6 are important for strength and colour of hair. Deficiencies of any of these nutrients are known to promote hair greying. B complex supplements are very useful in preventing greying.
Premature graying may be reversed with vitamin B12 supplementation only if vitamin B12 deficiency is the cause. If you are graying due to other factors, such as genetics, zinc deficiency, and medications, your gray hair cannot be reversed.
Vitamin D:
For this, one must get sun exposure for 10-15 minutes between 9 am to 11 am every day. Vitamin D also contributes to the stimulation of new and old hair follicles, which is why it is essential in preventing the greying of hair.
Although the primary cause of premature hair graying (PHG) is considered to be genetic, certain environmental factors also play a role. Trace element deficiencies such as Vitamin B12, Vitamin D3, and calcium may also be associated with PHG.
Vitamins D, B12, B9, B5, and minerals like iron, calcium, and zinc can help reverse gray hair. Vitamin supplements can also prevent premature hair graying.

Significantly exceeding this dose, however, can cause illness. In general, the symptoms of vitamin toxicity include nausea, gastrointestinal problems like constipation and diarrhea, hair loss, rashes, and nerve damage.
Supplements are easily available over the counter either in combination with B-complex supplements or alone in the form of cyanocobalamin. However, it is not recommended to consume vitamin B12 supplements without consulting a doctor as they can interfere with some other medicines.
POSSIBLE ETIOPATHOGENESIS OF GRAYING

Dr. Kraleti doesn't recommend plucking or pulling the hairs out. “If there is a gray hair you must get rid of, very carefully cut it off. Plucking can traumatize the hair follicle, and repeated trauma to any follicle can cause infection, scar formation or possibly lead to bald patches.”
Iron deficiency can also lead to grey hair. Iron is a vital mineral that helps create haemoglobin – the substance found in RBCs. Lacking an adequate amount of iron means lesser blood cells, which leads to insufficient oxygen supply to your scalp. Naturally, this causes grey hair at a young age.
