Hair analysis is now considered an effective method for identifying drug and alcohol consumption. Hair offers an extended timeline for detecting substance usage by capturing biomarkers within the hair strand as it grows. When sampled close to the scalp, hair can show evidence of drug and alcohol presence for up to three months. Collecting hair is straightforward, relatively resistant to tampering, and easy to transport.
A sample of 1.5 inches, comprised of around 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp, yields 100mg, which is the optimal amount for screening and verification. If EtG, additional tests, or tests beyond 10 panels are required, a specimen of 150mg is advised. It is suggested to use a jeweler’s scale to weigh the sample. In cases where scalp hair isn't available, a comparable quantity of body hair can be used. The term "head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing in the laboratory's system. This step ensures the sample was properly sealed and dispatched, assigns a random Laboratory Accessioning Number (LAN), and completes any additional data entry absent from an electronic chain of custody system.
Screening is a preliminary assessment for drug abuse. Although it's cost-effective for ruling out substance use in most samples, a positive Screen result needs verification for court admissibility. Presumptive positive samples in Screening require a follow-up confirmation.
If Screening yields a presumptive positive, additional hair from the initial sample is set aside for Extraction. This phase involves obtaining drugs from hair at lower concentrations than alternative methods like urine or oral fluid, making hair analysis the most challenging screening technique.
Verification of any positive Screen outcome is done through GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positives undergo washing before verification if necessary. From Accessioning through Confirmation, the complete laboratory procedure is scrutinized according to both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 accreditation.

Note: Though often termed "hair follicle tests", the analysis is conducted on the hair strand, not on the follicle beneath the scalp.
