The mineral zinc is involved in tissue growth and repair — and that includes hair growth. It also helps keep the oil glands around the hair follicles working properly. Low levels of zinc can cause hair loss, slow growth, and dandruff. But the amount you get from eating foods rich in zinc — such as oysters, crab, clams, liver, lean beef, most nuts and seeds, peanut butter, wheat germ, fat-free yogurt, and cheese — is plenty to keep your tresses gorgeous. Aside from a multivitamin that provides up to 100 percent DV, I don't recommend taking extra zinc supplements because excess zinc can inhibit the body's ability to absorb copper, a minor but necessary mineral.
