The perception of hair testing as a potent mechanism for identifying drug and alcohol consumption has grown. Hair captures biomarkers within its fibers as it grows, offering an extended history of substance use. By collecting hair near the scalp, one can achieve a detection period of roughly three months for alcohol and drugs. Hair collection is straightforward, not easily tampered with, and simple to transport.
Gathering a 1.5-inch segment of approximately 200 strands of hair (close to a #2 pencil in size) from the scalp yields 100mg of hair, considered the perfect sample size for both screening and confirmation. For EtG, additional analyses, and tests exceeding 10 panels, a 150mg specimen is advisable. It's best to weigh the specimen using a jeweler’s scale. If scalp hair isn't accessible, a similar quantity of body hair can be used. "Head hair" specifically pertains to scalp hair, while "body hair" encompasses all other hair forms (like facial, axillary, etc.).
Process Overview
The procedure for processing a drug test result in the lab consists of four principal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the sample’s initial entry into the lab's system, ensuring it was sealed and dispatched correctly, issuing a unique LAN (Laboratory Accessioning Number), and completing any extra data entry absent in an electronic chain of custody setup.
Screening acts as a preliminary rapid test for substance abuse. Although Screening economically helps eliminate drug use across most samples, any positive findings must undergo confirmation for legal admissibility. Samples that test presumptively positive in Screening necessitate subsequent confirmation.
Should a sample test presumptively positive during Screening, more hair is taken from the original specimen for the Extraction stage. Here, drugs are extracted from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting why hair drug testing is challenging.
Confirmation of any positive screening is done using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as required. The complete lab process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Referred to often as "hair follicle tests", the test evaluates the strand itself, not the follicle beneath the scalp.

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.
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. As we embrace these advancements, we pave the way for a safer, healthier society, where drug testing and analysis serve as powerful tools in protecting public health and maintaining integrity in various sectors. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.
