The use of hair testing is regarded as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and drug use by embedding biomarkers within the strands of developing hair. When clipped close to the scalp, hair can reveal up to a 3-month period of alcohol and drug detection. The collection process of hair is straightforward, relatively resistant to tampering, and convenient for shipping.
To obtain an ideal test sample, a 1.5-inch section containing roughly 200 hair strands, with a weight of 100mg, should be taken nearest to the scalp. For additional tests such as EtG, or tests exceeding 10 panels, 150mg of the sample is advisable. Measuring the sample with a jeweler’s scale is suggested. If scalp hair is not present, body hair of equal quantity can be used. References to head hair pertain exclusively to scalp hair, whereas body hair encompasses other types (facial, axillary, etc.).
Process Overview
Key phases in processing a laboratory drug test result include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing within a laboratory’s system. It involves confirming the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and executing any supplementary data entry absent from an electronic chain of custody system.
Screening conducts a preliminary rapid assessment for drug abuse. Although Screening cost-effectively rules out drug use in most samples, a confirmed positive is essential for court validity. Positive results in Screening require additional confirmation.
Should the Screening indicate a presumptive positive, additional hair is extracted from the initial specimen for the Extraction phase. Here, drug extraction occurs at a significantly reduced concentration compared to other methods (like urine or oral fluids), making hair drug screening the most challenging technique to execute.
Any positive results from screenings undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, presumptive positive samples are cleansed as necessary. Every step, from Accessioning to Confirmation, is examined under both the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: The term "hair follicle tests" is often a misnomer, as the test examines the hair strand, not the hair follicle located 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.
