Abstract: A dietary supplement which is useful for the promotion of healthy hair and pigment restoration in human subjects is provided. The dietary supplement supplies useful nutrients for hair growth, development, and pigmentation. In some instances, the use of the present dietary supplement can retard, prevent, suppress, and/or even reverse the graying of hair. Thus, at least for some already-turned gray individuals, the natural hair color can be restored, and maintained, naturally without the use of dyes, colorants, or the like. The dietary supplement contains, in effective amounts, a copper salt; para-aminobenzoic acid or salts thereof; pantothenic acid or salts thereof; and vitamin B6 in an appropriate carrier.
