Typically, 1.5 to 2 inches of hair is needed from the scalp, or body hair can suffice in many instances. Hair tests can detect drugs, alcohol/ETG, or other tailored testing options.
Recently, hair follicle drug testing has become a preferred method due to its extensive detection capability. Many employers, legal systems, and Substance Abuse experts now favor hair tests over traditional urine tests. Employers with strict no-drug policies, courts, and those on probation find hair tests particularly useful. A significant advantage is the extended detection timeline of up to 90 days, ensuring rigorous collection and making it difficult to defeat. Nonetheless, for detecting drug use in the prior 5 days, urine tests remain the gold standard.

Hair testing is recognized as an effective means for identifying drug and alcohol consumption. Hair acts as a repository of a prolonged history of substances by capturing biomarkers in the hair's growing fibers. When acquired near the scalp, hair can yield roughly a 3-month detection window for substances. Hair collection is straightforward, somewhat resistant to tampering, and easy to transport.
A 1.5-inch segment comprising around 200 hair strands (approximately equivalent to a #2 pencil's thickness) closest to the scalp will provide 100mg of hair, the optimal sample for screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, a 150mg specimen is advisable. We suggest determining the specimen's weight on a jeweler's scale. If scalp hair is inaccessible, an equivalent quantity of body hair may be gathered. References to head hair pertain exclusively to scalp hair. Body hair pertains to all other types (facial, axillary, etc.).
Process Overview
The primary phases in processing a drug test result in a lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the sample's initial processing into the laboratory system. This process involves confirming the sample's proper sealing and shipping, assigning a randomly-generated LAN (Laboratory Accessioning Number), and fulfilling any additional data entry not captured by an electronic chain of custody system.
Screening includes an initial rapid assessment for drugs of abuse. While Screening is an economical approach to exclude drug use in most samples, a positive screen needs confirmation to be valid in a legal context. All samples presumed positive in Screening require further confirmation.
If a sample shows a presumptive positive result in the Screening phase, additional hair is extracted from the original specimen for Extraction. In this step, drugs are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening a more complex process.
Confirmation for any positive screening result occurs via GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed before confirmation as necessary. The comprehensive laboratory process from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
