Hair testing works by analyzing the metabolites of drugs that are deposited into the hair follicles through the bloodstream When a person consumes drugs, the substances are metabolized by the body and eventually find their way into the hair These metabolites become trapped in the hair shaft as the hair grows, providing a record of drug use over time.
