Hair analysis is recognized as a potent method for identifying drug and alcohol consumption. Hair records a detailed history of substance usage by capturing biomarkers within the fibers of the developing hair strand. When sampled near the scalp, hair can reveal substance use within a timeline of roughly three months. Collecting hair is straightforward, somewhat resistant to tampering, and easily transportable.
A hair sample of 1.5 inches, consisting of around 200 strands (about the thickness of a #2 pencil) nearest to the scalp, provides 100mg of hair, which is the optimum quantity for testing and validation. For EtG, additional testing, or analyses exceeding 10 panels, 150mg is advised. We suggest using a jeweler’s scale for weighing. In the absence of scalp hair, a comparable volume of body hair can be used. When mentioning head hair, we refer solely to scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test result involves Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into a laboratory’s system. It includes confirming the sample was properly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing any supplemental data entry not covered by an electronic custody system.
Screening represents an initial quick evaluation for drug presence. While Screening offers a cost-effective strategy to negate drug use in most cases, a positive screen must be verified to be legitimate in legal proceedings. Any samples that show a presumptive positive result during Screening require subsequent confirmation.
If a sample shows a presumptive positive result during the Screening phase, additional hair is obtained from the initial sample for Extraction. During Extraction, drugs are retrieved from hair at much lower concentrations than in other methods (e.g., urine or oral fluid), which makes hair drug testing the most challenging method to execute.
Confirmation of any positive Screening result is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are cleansed before confirmation as needed. The entire lab process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests," the analysis actually examines the hair strand, not the follicle under 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.
