Hair analysis testing has been a widely used tool by the alternative health community. The claims of what can be learned and confirmed by hair analysis are much broader than can be supported scientifically. Only cautious conclusions can be drawn regarding mineral status from a hair analysis. Conclusions regarding heavy metal burden and toxicity are more reliable, but contamination and elimination rate must be considered carefully. Some doctors only use hair analysis as a screening tool for heavy metals, relying upon other tests to confirm the suggested findings of hair analysis, or bypassing hair analysis entirely in favor of other more reliable methods of testing heavy metal burden and mineral imbalances.
