Hair examinations are recognized as an effective method for detecting the presence of drugs and alcohol. The fibers of hair strands capture biomarkers, providing a prolonged history of substance use, including alcohol. When samples are collected near the scalp, hair can reveal up to a three-month detection period for alcohol and other drugs. Collecting hair is straightforward, somewhat resistant to tampering, and convenient to transport.
A sample measuring 1.5 inches, consisting of roughly 200 hair strands (about the thickness of a #2 pencil), taken closest to the scalp yields 100mg of hair, which is the optimal amount for both screening and confirmation processes. For EtG, additional tests, and panels exceeding 10, a sample size of 150mg is recommended. It's advised to measure the sample using a jeweler’s scale. If scalp hair cannot be obtained, an equivalent volume of body hair can be used. The term "head hair" strictly refers to scalp hair, while "body hair" encompasses all other types (e.g., facial, axillary).
Process Overview
The laboratory processing of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
The initial stage, Accessioning, incorporates a sample into the laboratory system. This process includes confirming the sample’s proper sealing and shipment, allocating a random LAN (Laboratory Accessioning Number), and completing any extra data entry not provided through an electronic chain of custody system.
The Screening stage consists of a preliminary, rapid assessment for drugs of abuse. Although Screening is a cost-efficient approach to eliminate drug use in most samples, a positive result requires confirmation for legal admissibility. Any samples that yield a presumptive positive in Screening require additional confirmation.
If Screening indicates a presumptive positive, more hair is extracted from the initial specimen for the Extraction phase. This stage involves extracting drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), which makes hair drug screening one of the most challenging methodologies.
Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS methods. Prior to confirmation, any presumptive positive samples are washed as necessary. The full laboratory process, from Accessioning to Confirmation, is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Note: Although commonly termed "hair follicle tests," the analysis targets the hair strand itself rather than the follicle beneath the scalp

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. 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.
Clinical Applications of hair testing are witnessed by the insight on environmental tobacco smoke exposure, assessed by hair analysis in a population of students and the study of in utero-exposure to drugs of abuse through neonatal hair analysis. Exposure to drugs was also important in cases of child abuse/neglect, when the clinical purpose of hair testing merge with its forensic applications.
The legal framework surrounding hair testing and the achievement of guidelines to ensure fairness, accuracy, and confidentiality in drug testing practices have also been discussed,and the SoHT consensus on general hair testing and testing for drugs of abuse was presented at the meeting and published as a Letter to the Editor.
