In recent times, drug testing increasingly includes hair follicle testing as a method. Employers, judicial systems, and substance abuse experts often prefer hair tests over urine tests. This approach is favored by workplaces with strict drug policies, courts, and on probation. Hair testing offers advantages such as an extended detection window of up to 90 days, overseen collection, and is extremely difficult to tamper with. For drug use in the past five days, urine tests remain most precise.

Hair analysis has gained recognition as a potent resource for identifying drug and alcohol consumption. Hair offers an extended timeline of drug and alcohol history by embedding biomarkers within the fibers of the growing strand. When gathered near the scalp, it can reveal a detection span of up to 3 months for drugs and alcohol. Hair collection is straightforward, relatively tamper-resistant, and conveniently packed for shipping.
A 1.5-inch segment of around 200 strands (comparable to a #2 pencil) taken closest to the scalp produces 100mg, the optimal amount for both screening and confirmation tests. For EtG, additional tests, and those beyond 10 panels, a 150mg specimen is advised. Utilizing a jeweler's scale is suggested for weighing. If scalp hair is not available, a comparable portion of body hair can be collected. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other hair types (e.g., facial, axillary).
Process Overview
The lab processing for drug test results involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial phase where a sample is incorporated into a lab's system. This includes verifying the seal and shipment integrity, assigning a LAN (Laboratory Accessioning Number), and completing any further data entry absent from an electronic chain of custody.
Screening is a preliminary rapid assessment for drug presence. Though Screening is cost-effective for excluding drug use in most samples, a positive finding requires confirmation for court admissibility. Presumptive positive samples in Screening demand further verification.
For samples flagged presumptively positive in Screening, additional hair is extracted from the original sample for Extraction. Here, drugs are isolated at much lower concentrations than other methods (e.g., urine, oral fluid), highlighting the difficulty in conducting hair drug tests.
Confirmation for any positive screening proceeds via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation, as needed. The complete lab process from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Despite often being termed "hair follicle tests," the exam actually analyzes the hair strand rather than 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.
