Hair evaluation has become recognized as a robust method for identifying drug and alcohol consumption. Hair strands archive a lengthy history of substances by capturing biomarkers within the hair's fibers as it grows. When cut close to the head, hair can yield up to roughly a three-month detection timeframe for drugs and alcohol. Hair collection is straightforward, fairly tamper-resistant, and easy to transport.
A 1.5-inch section consisting of around 200 hair strands (about the circumference of a #2 pencil) nearest the scalp provides 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, a 150mg specimen is suggested. It's advisable to weigh the sample using a jeweler’s scale. In the absence of scalp hair, a comparable quantity of body hair can be collected. Head hair refers specifically to scalp hair, whereas body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The four principal phases in laboratory processing of a drug test include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial incorporation of a sample into a laboratory’s system, verifying proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data not covered by an electronic chain of custody system.
Screening involves a preliminary assessment for substances of abuse. Although Screening efficiently excludes drug use in most samples due to its cost-effectiveness, a positive screen requires validation to be allowed in legal settings. Samples showing presumptive positivity during Screening necessitate a secondary verification.
In the event of presumptive positivity during Screening, additional hair is extracted from the primary specimen and set for Extraction. At this stage, drugs are isolated from the hair at a much lower concentration than with other methods (like urine or oral fluid), making hair drug screening the most challenging method to execute.
The Confirmation of positive screening results is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity undergo washing as necessary before confirmation. The entire lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair program and the ISO / IEC 17025 accreditation standards.

Limitations:
Note: Though often termed "hair follicle tests", the analysis is conducted on the hair strands and not the follicles beneath the scalp.
