Recently, the integration of hair follicle drug testing has become more common in drug testing methodologies. Today, numerous employers, judicial bodies, and Substance Abuse professionals prefer a hair drug test over the traditional urine test. Employers advocating zero-tolerance policies, court systems, and those on probation find the hair follicle test invaluable for its prolonged detection period, often extending to 90 days. The process ensures accuracy via an observed collection, making it nearly impossible to falsify. Nevertheless, for detecting recent drug use within a five-day window, urine tests remain superior.

Hair testing is regarded as a robust method for identifying drug and alcohol consumption. Hair preserves a timeline of alcohol and drugs by embedding markers in the fibers as the hair grows. If sourced near the scalp, hair can offer a detection range of up to roughly three months for alcohol and drugs. The collection process is straightforward, tampering is somewhat challenging, and shipping is uncomplicated.
A 1.5-inch segment of about 200 strands of hair (roughly equivalent to a #2 pencil in thickness) nearest to the scalp provides 100mg, the preferred quantity for analysis and verification. For EtG, supplementary, and/or more than 10-panel tests, a 150mg sample is advisable. We suggest measuring the sample using a jeweler’s scale. If scalp hair is nonexistent, the same quantity of body hair is acceptable. By head hair, we refer strictly to scalp hair. Body hair includes all other varieties (beard, underarm, etc.).
Procedure Synopsis
The drug testing procedure in a lab comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary handling of a sample into the lab system. This process encompasses validating that the sample was adequately sealed and delivered, assigning an arbitrary LAN (Laboratory Accessioning Number), and finalizing any missing data input apart from that included in an electronic chain of custody.
Screening acts as an initial efficient evaluation for the presence of drugs. While Screening is a cost-saving method to identify negative drug use in most cases, a positive result necessitates confirmation to be valid in legal settings. Any samples with a tentative positive result in Screening require additional verification.
If detected positive during the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. In this phase, drugs are extracted from hair at a much subtler concentration than other approaches (such as urine or oral fluid), making hair drug screening the most complex methodology to execute.
Confirmation of any positive Screening result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with a tentative positive result are cleansed before confirmation if necessary. The full laboratory sequence from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair criteria and the accreditation to ISO / IEC 17025 standards.

Note: Despite being often called "hair follicle tests", these tests analyze the hair strand, not the follicle beneath the scalp.

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.
In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
