Hair analysis has become recognized as an influential technique for identifying substance and alcohol intake. Hair encapsulates a comprehensive record of alcohol and drug consumption by preserving biomarkers within the strands of growing hair. When obtained near the scalp, hair can reveal up to a 90-day detection period for substances. Hair is uncomplicated to gather, moderately challenging to tamper with, and straightforward to transport.
A 1.5-inch portion of roughly 200 hair strands (approximately the width of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample for both screening and confirmation. For EtG additions and/or tests exceeding 10 panels, a 150mg specimen is advisable. Using a jeweler’s scale to weigh the specimen is recommended. In the absence of scalp hair, an equivalent amount of body hair may be used. When mentioning head hair, we mean scalp hair exclusively. Body hair encompasses all other hair types (such as facial and axillary).
Process Summary
The laboratory handling of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary process of logging a sample into a lab's system. This step includes confirming that the sample was sealed and transported correctly, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry not covered by an e-chain of custody system.
Screening consists of an initial, rapid assessment for drugs of abuse. While Screening is a cost-effective method to eliminate drug use in most samples, a positive result needs confirmation for legal admissibility. Samples presumptively positive in Screening require subsequent confirmation.
If a sample tests positive in the Screening phase, additional hair is extracted from the initial specimen for the Extraction stage. Here, drugs are isolated from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), thereby making hair drug screening a challenging methodology.
Confirmation for any positive Screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo a cleansing before confirmation as needed. The complete laboratory sequence from Accessioning to Confirmation is audited according to both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Note: Commonly misnamed as "hair follicle analyses", the analysis targets the hair strand rather than the follicle beneath the scalp.
