The History and Process of Hair Testing
Hair testing was discovered over 25 years ago as scientific studies showed hair was like a tape recording being both stable and permanently embedding the data in the hair.
Hair testing is now used regularly in the fields of drug testing, forensic science, nutritional and mineral analysis and hormone testing.
Scientists see hair analysis as one of the most exciting areas for development due to the ease of providing samples and the history in hair that last much longer than blood and urine.
Along with the simplicity, hair testing is non-invasive.
