Folic acid stimulates the growth of longer, healthier hair, especially when used in conjunction with other vitamin and mineral supplements. According to New York Magazine, a great supplement mixture for hair growth includes folic acid, biotin and vitamins A, C and E. While these nutrients can be obtained by adding vitamin-rich food to the diet, taking supplements is usually an easier way to harness their hair-growth potential.
Folic acid works in several ways to stimulate hair growth. It helps build healthy red blood cells, and healthy red blood cells are better able to carry nutrients and oxygen to the scalp. Folic acid also helps renew the cells that cause hair growth. A deficiency of folic acid in the diet may result in premature graying and baldness. Adding folic acid back into the diet is likely to slow the progress of these conditions.
Folic acid supplements taken on a daily basis stimulate increased hair growth, but consumers must never take more than the amount recommended on the label. Folic acid supplements taken along with biotin provide maximum effectiveness, as folic acid helps the body better utilize the biotin to build healthy hair. Those who prefer to get their nutrients from foods rather than from supplements can increase their intake of spinach, lentils, asparagus, avocado and mushrooms, all of which are high in folic acid.
