Hair testing is recognized as an effective means for identifying drug and alcohol consumption. Hair captures a comprehensive timeline of substance use by embedding biomarkers within the growing strand's fibers. If gathered near the scalp, hair can reveal alcohol and drug presence for approximately three months. Collection is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch segment of about 200 hair strands (about a #2 pencil's thickness) nearest to the scalp yields 100mg, the optimal quantity for screening and validation. For EtG, supplementary tests, and/or tests exceeding 10 panels, 150mg of the sample is advisable. It is recommended to use a jeweler’s scale for weighing the sample. Should scalp hair be unavailable, an equivalent amount of body hair is collectable. "Head hair" specifically denotes scalp hair. "Body hair" encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step where samples are entered into a lab's system. This involves ensuring correct sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data input absent from an electronic chain of custody system.
Screening entails an initial rapid assessment for drug abuse. Although Screening is a cost-efficient method to dismiss drug use in most samples, positive results must be verified for legal admissibility. Samples showing presumptive positivity in Screening necessitate further confirmation.
Should a sample be presumptively positive in the Screening stage, additional hair is sourced from the initial specimen and prepped for Extraction. At this phase, drugs are extracted from hair at a much lower concentration than other methods (ex. urine or oral fluid), which is why hair drug screening is the most challenging method to execute.
Confirmation of any positive screening results is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation as necessary. The comprehensive lab process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Limitations:
Note: Despite often being called "hair follicle tests", the analysis focuses on the hair strand rather than the follicle beneath the scalp.
