Hair testing is increasingly recognized as an effective method to identify drug and alcohol use. It offers a long-term record by embedding biomarkers within the fibers of hair strands as they grow. When collected from near the scalp, hair can offer a detection period of up to approximately three months for alcohol and other drugs. This method is easy to collect, somewhat resistant to tampering, and simple to transport.
A sample measuring 1.5 inches long and consisting of around 200 hair strands (roughly the width of a #2 pencil) is ideal, weighing about 100mg for initial screening and confirmation. For EtG or tests exceeding 10 panels, a 150mg sample is suggested. It’s advisable to use a jeweler's scale for specimen measurement. In the absence of scalp hair, body hair can be substituted in equal amounts. "Head hair" refers specifically to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The key stages in laboratory processing a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial step where a sample is processed into a lab’s system. This procedure verifies the sample's proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes any further data entry, not included in an electronic chain of custody system.
Screening is a quick initial evaluation for drugs. This step is cost-effective for eliminating drug usage in most samples; however, a positive result must be confirmed to be court-admissible. Presumptively positive samples from this step require additional confirmation.
For samples testing presumptive positive in Screening, more hair is extracted from the original specimen for the Extraction stage. Here, drugs are extracted from hair at lower concentrations than other methods (like urine or oral fluid), which is why hair drug testing is the most challenging technique to execute.
Confirmation of any presumptive positive screening result employs GC/MS, GC/MS/MS, or LC/MS/MS methods. Before confirmation, all presumptive positive samples are washed as necessary. The complete laboratory process from Accessioning to Confirmation undergoes review under the CAP (College of American Pathologists) Hair designation, adhering to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Though often termed "hair follicle tests", the analysis actually focuses on the hair strand rather than the scalp’s hair follicle.

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.
