In recent times, hair follicle drug testing has gained popularity as a method for detecting substance use. Numerous employers, judicial systems, and substance abuse experts now opt for hair testing over the conventional urine method. Hair follicle tests cater to employers with strict no-drug policies, probation authorities, and courts. The key advantage of these tests lies in their extended detection window—up to 90 days—and the supervised collection method makes tampering nearly impossible. Nonetheless, for identifying drug use within the past 5 days, urine tests remain most precise.

Hair testing is regarded as a crucial means for detecting drug and alcohol consumption. It offers a long-term record of alcohol and other substances by embedding biomarkers within the fibers of the developing hair strand. When taken near the scalp, hair can reveal up to a 3-month detection span for alcohol and drugs. Hair is straightforward to collect, somewhat resistant to tampering, and simple to transport.
A sample of 1.5 inches comprising around 200 hair strands (approximately the width of a #2 pencil) closest to the scalp will yield 100mg of hair, the optimal amount for analysis and validation. For EtG, add-ons, or tests exceeding 10 panels, 150mg of the sample is advised. Using a jeweler’s scale for weighing the sample is suggested. If head hair is not available, an equivalent quantity of body hair can be obtained. By head hair, we mean scalp hair exclusively. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test outcome involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase of incorporating a sample into a lab's system. This stage includes confirming that the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.
Screening performs an initial, rapid assessment for substances of abuse. Although Screening is an economical method to eliminate drug usage in most samples, a positive screen needs confirmation for courtroom acceptance. Samples that are presumptively positive in Screening necessitate secondary confirmation.
Should a sample be deemed presumptively positive in the Screening phase, more hair is extracted from the initial sample and readied for Extraction. Here, drugs are isolated from the hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), rendering hair drug screening a highly challenging procedure to execute.
Confirmation of any positive screening outcome is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. The complete lab process from Accessioning to Confirmation is examined according to both the CAP (College of American Pathologists) Hair specification and accreditation to ISO / IEC 17025 standards.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.
It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
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.
