Hair testing is regarded as a robust means of detecting drug and alcohol usage. It offers a prolonged history of alcohol and drugs by embedding biomarkers in the fibers of the maturing hair strand. By taking samples near the scalp, hair can reveal up to roughly a 3-month timeframe for alcohol and drug detection. It's straightforward to gather, fairly hard to tamper with, and convenient to transport.
A 1.5-inch section comprising roughly 200 hair strands (similar in size to a #2 pencil) nearest the scalp should provide 100mg, an optimal sample size for screening and confirming. For tests such as EtG or those beyond 10 panels, 150mg of the sample is suggested. It's advisable to weigh the sample using a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair can be taken. "Head hair" refers solely to scalp hair, whereas "body hair" encompasses other types (facial, axillary, etc.).
Process Overview
There are four primary stages in the lab processing of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning functions as the initial step in processing a sample within a laboratory's framework. This step comprises ensuring proper sealing and shipping of the sample, allocating a random LAN (Laboratory Accessioning Number), and any extra data entry absent in an electronic chain of custody system.
Screening consists of a preliminary rapid check for misuse of drugs. Although Screening efficiently excludes drug usage in most samples, a positive result from screening must be verified to be valid in legal proceedings. Samples showing a presumptive positive in Screening necessitate a secondary confirmation.
If Screening indicates a presumptive positive, more hair is extracted from the primary sample for the Extraction process. This step involves extracting drugs from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), accounting for why hair drug testing ranks as the most challenging methodology.
Confirmation for any positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo a pre-confirmation wash as necessary. The entire lab process, from Accessioning to Confirmation, is subject to review under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Though commonly titled "hair follicle tests", such tests assess 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. 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.
