Will a zinc supplement benefit my childs hair loss?

Is her zinc low?: Your are correct, zinc supplementation can be beneficial for hair or skin problems--however, that is only applicable when the zinc level in the body is inadequate. Giving more zinc than necessary to a child that is not deficient is not going to help however. Please have your child examined by a board-certified pediatrician or dermatologist. A blood test for zinc may prove useful, which she can do.
