VITAMINS AND HUMAN GRAY HAIR
The production of achromotrichia in animals by dietary means and the alleviation of the experimentally produced condition by inclusion in the diet of pantothenic acid or some other vitamin of the B complex led to the hope that similar factors might be effective in restoring the original color to gray hair in man. Some studies have suggested that administration of para-aminobenzoic acid or a preparation containing pantothenic acid is followed by darkening of previously gray hair in man.1 In view of the widespread publicity given to so-called anti-gray hair factors and of newspaper advertising promoting the sale of calcium pantothenate to persons with gray hair, a recent report by Brandaleone, Main and Steele2 is of particular interest.
