The popularity of hair follicle drug tests has surged in recent years for drug screening. Increasingly, employers, courts, and substance abuse counselors prefer this method over standard urine tests. Hair tests are ideal for employers enforcing zero-tolerance policies, courts, and those on probation. Their main advantage is their extended detection window—up to 90 days; they are collected under supervision and are almost impossible to tamper with. Despite this, urine tests remain the most accurate for recent drug usage within the last five days.

Hair testing is now recognized as an effective method for detecting drug and alcohol usage. Hair captures long-term substance histories by preserving biomarkers in the fibers of the growing strand. When sampled correctly near the scalp, it yields up to a 3-month window for substance detection. Hair collection is straightforward, relatively tamper-resistant, and easy to transport.
A 1.5-inch segment of roughly 200 hair strands (similar to a #2 pencil) closest to the scalp provides 100mg of hair, which is the preferred amount for screening and confirmation. For EtG evaluations, additional testing, and/or panels exceeding 10, a 150mg specimen is advisable. Using a jeweler’s scale for weighing is suggested. In the absence of scalp hair, a comparable amount of body hair is acceptable. "Head hair" pertains specifically to scalp hair, whereas "body hair" includes all other variants (like facial or axillary hair).
Process Overview
The core steps of laboratory drug test processing are Accessioning, Screening, Extraction, and Confirmation.
Accessioning initiates the integration of a specimen into the lab system. This ensures the sample's proper sealing and shipment, allocates a random LAN (Laboratory Accessioning Number), and finalizes any outstanding data entries absent from an electronic custody chain.
Screening performs a preliminary drug abuse assessment. Although cost-effective for negating substance use in most specimens, court-admissible results require a confirmed positive screen. Presumptive positive samples from Screening need further validation.
Should a sample show potential positivity at Screening, further hair is retrieved from the initial sample for Extraction, where drug levels are quantified in much lower concentrations compared to other methods (like urine or oral fluids), making hair drug screening exceptionally challenging.
Verification of positive results is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. Necessary washing is conducted on presumptive positive samples prior to final confirmation. The complete procedural cycle from Accessioning to Confirmation undergoes review in compliance with both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 standards.
