Hair testing is widely recognized as an effective method for detecting drug and alcohol use. Hair captures a long-term record of alcohol and drugs by trapping biomarkers within the strands as they grow. When taken close to the scalp, hair offers a detection window of up to about 3 months for alcohol and drugs. Hair is straightforward to collect, somewhat resistant to tampering, and easy to ship.
A sample of 1.5 inches of about 200 hair strands (similar to the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal amount for screening and confirmation. For EtG, additional tests, or screenings over 10 panels, it's best to have 150mg of the sample. We suggest using a jeweler’s scale to weigh the specimen. If scalp hair is not available, an equivalent quantity of body hair can be used. When mentioning head hair, we mean only scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The laboratory process for a drug test result includes four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning begins with integrating a sample into a lab’s system. This step ensures the sample is sealed and shipped correctly, assigns a unique LAN (Laboratory Accessioning Number), and fills in any missing data not captured by an electronic chain of custody system.
Screening is a preliminary and quick check for drugs of abuse. While screening is efficient for ruling out drug use in most samples, a positive result needs confirmation to be accepted in court. Any samples that show a presumptive positive in screening need further confirmation.
If screening suggests a positive result, additional hair is taken from the sample for the Extraction stage. Here, drugs are extracted from hair at far lower concentrations than in methods like urine or oral fluid, making hair drug screening one of the more challenging methodologies.
Confirmation of a positive screening result is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive are washed as necessary prior to confirmation. The complete process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 accreditation 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. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.
