Heavy Metal Toxicity.
Although human hair is technically dead, the minerals present in the hair cell during its formation are locked within the hair structure. Minerals as well as toxic metals in the hair are in a higher concentration than in your blood, making these metal elements easier to measure through hair analysis, without any surgery.
Hair is a soft tissue of the human body; testing the hair is obtaining the equivalent of soft-tissue biopsy, without any surgery. Cost and wealth saving.
Hair analysis is an average reading over a several-month period; it gives a large picture over time of the body's metabolic changes.
Hair analysis and its diagnostic value were once considered controversial but due to stricter standards within the industry and better handling of samples, accuracy and reliability are now excellent. The U.S. Environmental Protection Agency states that human hair analysis is an accurate, inexpensive screening tool for heavy metal toxicity.
