Vitamin E

This antioxidant increases blood flow and promotes healthy hair and skin. Wheat germ oil, soybeans, raw nuts and seeds, leafy green vegetables and dried beans provide rich sources of vitamin E.

Dermatologist Dr. Jeffrey Benabio recommends biotin specifically for facial hair growth. Biotin promotes the production of keratin and promotes hair and nail growth. Whole grains, liver, rice, milk, egg yolks and brewer’s yeast contain healthy levels of biotin.

Inositol

One of the B vitamins, inositol maintains health of hair follicles. Include liver, whole grain, brewer’s yeast and citrus fruits in your diet to gain the benefits of inositol.

Niacin

Another B vitamin, niacin promotes blood circulation. Fish, poultry and wheat germ provide sources of this vitamin. Consult your physician before adding niacin supplements. Taking too much can lead to the dilation of blood cells, which usually results in a temporary sensation of heat.
