Hair Tissue Mineral Analysis (HTMA for short) is a laboratory test for 20 minerals and toxic metals in your hair. The balance of minerals in your hair can tell you about your adrenal and thyroid function, metabolic type, stress patterns, immune system, and much more. Most importantly, hair analysis can help determine which vitamins and minerals you need to rebalance your body chemistry and restore energy production—the key to healing most health issues. Hair analysis is unlike other tests because it provides insight at the cellular level, which is where most chemical reactions occur. This is why hair analysis often reveals significant imbalances even when other tests are normal.
