Focus - Hair Analysis Hair Analysis Hair analysis is touted by some alternate practitioners for determining nutritional status. The medical literature offers no support for this position.
Some practitioners claim that trace mineral status can be assessed with hair samples.
There are numerous fallacies behind this claim. Minerals are selectively stored in different tissues. Blood is usually the preferred test sample because it transports nutrients to all parts of the body. The mineral content also changes depending on distance from the roots of the hair. There is no justification for using hair analysis for any nutritional condition.
