Over the years, hair follicle drug testing has increasingly become a preferred method for screening. Many employers, judicial systems, and substance abuse professionals now opt for hair over the traditional urine tests. It's especially favored by employers with strict no-drug policies, the courts, and probation services. The standout advantage is its extended detection window, up to 90 days, conducted under supervision to ensure integrity, and offering minimal chance for deceit. Nonetheless, for very recent drug use (within 5 days), urine tests remain the most accurate.

Hair testing has emerged as an effective method for identifying the usage of drugs and alcohol. It offers a prolonged historical record of substance use by embedding biomarkers within the strands of hair as they grow. When taken near the scalp, hair can provide a detection period of up to about three months for substances like alcohol and drugs. Collecting hair is easy, tampering with it is challenging, and it is straightforward to transport.
A 1.5-inch section consisting of approximately 200 hair strands (roughly matching the diameter of a #2 pencil) closest to the scalp yields 100mg of hair, which is the preferred amount for both screening and confirmation. For EtG, supplemental tests, or panels exceeding 10, a 150mg specimen is suggested. It is advisable to weigh the sample using a jeweler’s scale. If no scalp hair is present, an equivalent quantity of body hair can be used. "Head hair" pertains exclusively to scalp hair, while "body hair" includes all other hair categories (like facial and axillary hair).
Process Overview
The laboratory processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step in integrating a sample into a laboratory's workflow. This step verifies the sample's proper sealing and shipping, assigns it a random LAN (Laboratory Accessioning Number), and logs additional data not captured by electronic chain of custody systems.
Screening is a preliminary assessment to check for substance use. While it is a cost-effective approach for excluding drug consumption in the majority of cases, a positive result in screening must undergo confirmation for legal acceptability. Presumptive positives in screening necessitate follow-up confirmation.
Should a sample indicate a presumptive positive in Screening, extra hair is extracted from the original sample for the Extraction phase. At this stage, drug extraction from hair occurs at concentrations far lower than those in alternative methods (like urine or oral fluid), making hair drug testing a more challenging procedure.
Any positive result from screening goes through confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Each presumptive positive sample is cleansed before confirmation, if necessary. The full lab procedure, from Accessioning through Confirmation, is conducted under CAP (College of American Pathologists) Hair standards and in compliance with ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Despite being commonly called "hair follicle tests", the procedure 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.
