Hair analysis is a recognized method for identifying drug and alcohol consumption. It captures a historical timeline of alcohol and drug intake by embedding biomarkers within the hair as it grows. When extracted near the scalp, hair can present a detection timeline of up to roughly 90 days for alcohol and other substances. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch segment of approximately 200 hair strands (comparable to the girth of a #2 pencil) near the scalp will yield 100mg of hair, which is the optimal sample size for both screening and verification. For EtG, add-ons, and/or tests beyond 10 panels, a quantity of 150mg is advised. It is recommended to use a jeweler's scale for weighing the sample. If scalp hair is not available, a similar quantity of body hair can be used. When mentioning head hair, it pertains solely to scalp hair. Body hair encompasses all other hair categories (e.g., facial, axillary, etc.).
Process Overview
The procedure for processing a drug test result in the lab encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step where a sample is incorporated into a lab’s system. This step includes ensuring the sample was adequately sealed and transported, generating a spontaneous LAN (Laboratory Accessioning Number), and completing any supplementary data entry not supported by an electronic chain of custody system.
Screening constitutes an initial rapid test for substance abuse. Even though Screening is cost-effective for negating drug usage in most samples, a positive screen necessitates confirmation to be valid in legal contexts. Samples that exhibit a preliminary positive outcome in Screening must undergo further confirmation.
If a sample is initially positive during the Screening phase, additional hair is extracted from the original sample for Extraction. At this phase, drugs are isolated from hair at significantly lower concentrations than other methods (such as urine or oral fluid), which renders hair drug screening a challenging procedure to execute.
GC/MS, GC/MS/MS, or LC/MS/MS techniques are employed to confirm any positive screening findings. All samples with presumptive positives are cleansed before confirmation, as required. The full lab process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair specification and the ISO / IEC 17025 accreditation.

Note: Commonly termed as "hair follicle tests", the procedure actually examines the hair strand instead of the follicle beneath the scalp
