Hair Analysis Testing for Identifying Heavy Metals, Microplastics, and Forever Chemicals
Summary
Researchers reviewed hair analysis as a non-invasive way to detect long-term buildup of environmental toxins — including microplastics, heavy metals, and 'forever chemicals' (PFAS) — in the human body, using the fact that contaminants get trapped in hair as it grows. The technique offers a record of past exposures and could guide personalized strategies for reducing harmful chemical loads.
Hair analysis offers a non-invasive method to assess long-term exposure to environmental toxins, including heavy metals, microplastics, and persistent organic pollutants (forever chemicals).By evaluating bioaccumulation patterns and nutrient imbalances, this technique provides valuable insights into individual health risks and supports targeted detoxification strategies.This paper reviews the methodologies, targeted substances, clinical applications, challenges, and future directions of hair analysis in environmental health.
