Please note: Urine and hair tests analyse different sets of metals and minerals. The hair analysis includes a broader range of toxic metals as well as essential elements that may not be captured in the urine test.
Hair is considered an excretory, rather than functional, tissue—making it a valuable tool for assessing long-term mineral and metal exposure. As proteins are synthesised in the hair follicle, elements become permanently embedded in the hair shaft, providing a time-based record of both nutrient status and toxic exposure.
Hair testing is a cost-effective and informative screening method for identifying excesses, deficiencies, or imbalances in mineral distribution. Nutritional elements such as magnesium, zinc, copper, selenium, and chromium in hair tend to correlate with levels in organs and tissues. Meanwhile, toxic elements like arsenic, aluminium, cadmium, lead, antimony, and mercury are often found at concentrations 200–300 times higher in hair than in blood or urine, making hair the preferred tissue for detecting recent toxic metal exposure.
This test may be particularly useful in cases of suspected heavy metal toxicity, high fish consumption, alopecia, chronic fatigue, depression, malabsorption issues, hypertension, impaired glucose tolerance, kidney dysfunction, low testosterone, vision problems, and neurological symptoms resembling Parkinson’s disease.
