Vitamins impact on Preventing Hair Loss

A lack of vitamin A may cause the hair to be coarse and ugly.

A deficiency of some of the B vitamins, of iron, copper, and iodine may cause hair disorders like falling of hair and premature greying.

Lack of inositol causes loss of hair. Any person having trouble with his or her hair should eat foods rich in inositol such as yeast, liver, and molasses. Research has, however, shown that women have a low requirement of inositol. Although this vitamin may help to stimulate the growth of a woman's hair, its lack is probably not a major cause of slow growth.

Women are generally deficient in iodine and vitamin B1, either of which can slow down circulation to the scalp to such an extent that hair may fall out and new hair grow in very slowly. Women who keep their diets adequate in iodine, the B vitamins and iron have a better growth of hair.
