In years past, hair follicle drug tests have become increasingly common in drug testing. Both employers with strict drug policies, legal systems, and substance abuse specialists now opt for hair testing over urine tests. Hair tests present benefits such as an extended period of detection—usually up to 90 days—taken during observed collection, making them difficult to manipulate. Conversely, urine tests remain superior when identifying recent drug use from the past 5 days.

Hair analysis is now regarded as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged timeline of alcohol and drug usage by embedding biomarkers within the fibers of the growing hair shaft. Hair collected close to the scalp can reveal a detection span of up to around three months for alcohol and other substances. The collection process for hair is straightforward, relatively resistant to tampering, and easily transportable.
A sample measuring 1.5 inches consisting of approximately 200 hair strands (comparable in size to a #2 pencil) near the scalp yields 100mg of hair, which is the preferred sample size for analysis and validation. For EtG assays, additional tests, and/or panels exceeding 10, a specimen weighing 150mg is advised. It's suggested to use a jeweler’s scale for weighing the sample. If scalp hair is absent, an equivalent amount of body hair can be gathered. When mentioning head hair, it pertains exclusively to scalp hair. Body hair encompasses all other hair types (such as facial, axillary, etc.).
Process Overview
The lab processing of a drug test result is divided into four essential stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial handling of a sample within a lab's system. This step entails confirming the proper sealing and shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry not covered by an electronic chain of custody system.
Screening is a preliminary expedited evaluation for drugs of abuse. Screening is a cost-efficient method to exclude drug usage in most samples, but a positive screen needs confirmation to be legally acceptable. Samples showing presumptive positive results in Screening require an additional confirmation step.
Upon a presumptive positive result during the Screening phase, additional hair is taken from the original sample and readied for Extraction. During Extraction, drug substances are retrieved from hair at a significantly lower concentration than with methods like urine or saliva tests, which is why hair drug analysis is among the most challenging methodologies.
Any positive results from Screening are confirmed by GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are washed as needed. The complete laboratory procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation.
