The hair follicle drug test has increasingly gained prominence over recent years as a standard method for drug testing. It is favored by various employers, judicial systems, and professionals in Substance Abuse treatment who mandate hair testing over the traditional urine tests. This test is adopted by entities adhering to strict drug-free policies, legal institutions, and for probation monitoring. Its principal merit is the extended detection time for substance intake, which can last nearly three months. Hair samples are collected under observation, ensuring the integrity of the process, and making tampering exceedingly difficult. Yet, for recent substance use assessment—the past five days—urine tests maintain their reliability.

Hair analysis has emerged as an effective method for identifying substance and alcohol usage. Hair offers an extended record of alcohol and drug consumption by embedding biomarkers within the fibers of the hair strand as it grows. When obtained near the scalp, hair can reveal up to around a three-month timeframe for detecting alcohol and drug usage. Hair is easy to gather, challenging to tamper with, and convenient to transport.
An ideal testing and confirmation require a 1.5-inch sample of nearly 200 hair strands (approximately the width of a #2 pencil) nearest to the scalp to yield 100mg of hair. For EtG, additional screenings, or tests exceeding 10 panels, 150mg of hair is advised. Utilizing a jeweler’s scale for weighing the sample is suggested. If scalp hair is not present, an equivalent volume of body hair may be used. The term "head hair" specifically pertains to scalp hair only, whereas "body hair" encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The four principal phases in laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial intake of a sample into a laboratory's workflow. This process encompasses ensuring the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry not provided by an electronic chain of custody system.
Screening provides an initial rapid evaluation for substances of abuse. Although Screening serves as a cost-effective method to exclude drug usage for most samples, a positive screen must be verified to be court-admissible. Any specimens that test presumptively positive during Screening necessitate a secondary verification.
Should a specimen be presumptively positive during the Screening phase, additional hair is extracted from the original sample and prepared for the Extraction process. During this phase, substances are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug analysis the most challenging method to execute.
Verification of a positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo cleaning prior to confirmation, as needed. The complete laboratory workflow from Accessioning to Confirmation undergoes review according to both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

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.
