PURPOSE ## Why would someone need a hair follicle drug test? Hair follicle drug tests are commonly used by employers, courts, [probation](https://amhnationwide.com/hair-follicle-drug-test-probation/) offices, and individuals who require a long-term drug use history. These tests provide a [detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) of about 90 days, making them suitable for safety-sensitive positions or legal requirements where recent and past drug use is relevant. PROCESS ## How does the hair follicle drug test work? The hair follicle drug test detects drug metabolites deposited in hair shafts from the bloodstream. A small sample of hair, usually from the scalp, is collected and analyzed in a certified lab. Because hair grows approximately half an inch per month, a 1.5-inch sample can reveal drug use over the prior 90 days. ORDERING ## Where to buy hair follicle drug test kits for personal use?

Hair follicle drug tests typically screen for commonly abused substances including marijuana, cocaine, opiates, amphetamines, methamphetamines, PCP, and others depending on the test panel. The test detects drug metabolites embedded in the hair shaft, providing a reliable record of use over several months. RELIABILITY ## Can hair follicle drug tests be beaten or produce false results? Hair follicle tests are difficult to alter because drugs are incorporated into the hair from the bloodstream. Professional collection and certified lab analysis, with every non-negative reviewed by a Medical Review Officer, reduce false positives and negatives. Passive exposure is unlikely to produce a positive result unless exposure is extreme and sustained.
