Hair testing is regarded as an effective method for identifying drug and alcohol consumption. It provides an extended history of substance use by capturing biomarkers within the hair strand fibers. When sampling near the scalp, hair can reveal drug and alcohol usage over a period of up to three months. Hair collection is straightforward, difficult to tamper with, and easy to transport.
A sample of 1.5 inches, comprising around 200 hair strands (similar in size to a #2 pencil) closest to the scalp, yields 100mg of hair, which is ideal for screening and confirming. For tests such as EtG, additional panels over 10, 150mg of the sample is suggested. Using a jeweler's scale to weigh the specimen is advisable. If scalp hair isn't accessible, a comparable quantity of body hair can be collected. When discussing head hair, we specifically mean scalp hair only. Body hair includes all other types of hair (facial, axillary, etc.).
Process Overview
The laboratory process for a drug test result includes four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial sample processing in the lab’s system. This step ensures that the sample was properly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and completes any missing data from an electronic chain of custody system.
Screening is a preliminary evaluation for substance usage. Although Screening is an economical method to exclude drug use for most samples, a positive screen must be confirmed for legal admissibility. Samples testing presumptively positive during Screening require additional confirmation.
In cases of presumptively positive results from Screening, additional hair is extracted from the sample for further Extraction. Here, drugs are isolated from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening one of the most challenging methods to execute.
Confirmation for any positive Screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing as necessary before confirmation. The complete lab process from Accessioning to Confirmation is conducted under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: The test is often named "hair follicle tests", but it actually evaluates the hair strand rather than 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.
