Foods that prevent gray hair

Hair turns grey due to a decrease in the production of melanin in the hair bulb, which gives the hair its colour. Certain foods have been found to assist melanin production and prevent the greying of hair, and these can be incorporated into your diet to maintain your natural colour.


Eating foods rich in vitamins A and B help prevent grey hair. To obtain vitamin A, the Fat Free Kitchen website suggests consuming dark green vegetables and yellow fruits. To get more vitamin B in your diet, eat fresh green, leafy vegetables, bananas, tomatoes, cauliflower, cereals, liver, kidney, yoghurt, yeast and wheat germ.

Herbs and Spices

Certain herbs and spices may prevent grey hair. Black pepper, black cumin, curry and ginger are among these. According to the Fat Free Kitchen website, an excessive intake in spices can lead to grey hair, so it is best to use them in moderation. The herbs brahmi, shikakai and polygonum multiflorum are known to help hair retain its colour. Polygonum multiflorum, also known as ho shou wu, is a Chinese herb that has been used to restore hair's natural colour. According to the Kwintessential website, this herb improves kidney and liver functioning, aiding in good health and increasing colour in the hair.

Iodine-Rich Foods

Foods rich in iodine can prevent grey hair. According to the Women Fitness website, fish is the main source of iodine. Bananas and carrots also contain sufficient amounts of Iodine. You can also use iodised table salt rather than sea salt or kosher salt to increase your iodine intake.


Minerals play an important role in the functioning of a healthy body. According to the Women Fitness website, a drop in melanin can be caused by a lack of the mineral copper, so eating a balanced diet with enough copper can keep melanin production active and healthy. According to the World's Healthiest Foods website, "tyrosinase, a copper-containing enzyme, converts tyrosine to melanin." Melanin is essential for the hair to maintain its colour. To obtain copper, you can eat calf's liver, crimini mushrooms, turnip greens, molasses, chard, spinach, sesame seeds, mustard greens, kale, summer squash, asparagus, eggplant, cashews, peppermint, tomatoes, sunflower seeds, ginger, green beans, potato or tempeh, according to the World's Healthiest Foods. For zinc, the Fat Free Kitchen suggests eating red meat, green vegetables and chicken. For iron, consume beef, dried apricots, parsley, eggs, red meat, wheat and sunflower seeds.
