Hair follicles drug test

Hair follicle drug testing is one of the most advanced and reliable methods for detecting substance use. Unlike urine or saliva tests, which typically capture recent drug use within hours or days, hair testing provides a long-term detection window of up to 90 days or more, depending on hair length. This makes it an invaluable tool for employers, courts, rehabilitation centers, and healthcare providers who require a comprehensive view of an individual’s drug use history.
