The popularity of hair follicle drug testing has surged in recent years. Many employers, courts, and substance abuse professionals now favor this method over traditional urine tests. Such tests are preferred by zero-tolerance employers, judicial systems, and probation officers due to their extensive detection period of up to 90 days, observed collection process, and near immunity to tampering, although urine tests remain superior for identifying drug use within the past 5 days.

Hair analysis has evolved into a valuable method for identifying drug and alcohol consumption. Hair can reveal long-term alcohol and drug history by capturing biomarkers within the developing hair strand's fibers. When extracted near the scalp, hair can offer a detection timeframe of about three months for alcohol and various drugs. Hair is easy to gather, relatively challenging to alter, and straightforward to transport.
A 1.5-inch section of around 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal quantity for testing and verification. For EtG, additional tests, or tests exceeding 10 panels, 150mg of hair is advised. We suggest measuring the hair on a jeweler’s scale. If scalp hair isn't available, an equivalent amount of body hair can be used. When mentioning head hair, it refers specifically to scalp hair. Body hair encompasses all other hair types (such as facial, axillary, etc.).
Process Overview
The lab processing of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step of incorporating a sample into a lab’s system. This step ensures the sample was properly sealed and delivered, assigns a random LAN (Laboratory Accessioning Number), and finishes any extra data entry not covered by an electronic chain of custody system.
Screening conducts an initial rapid assessment for drugs of abuse. Although Screening is cost-efficient for excluding drug use in most samples, a positive result requires confirmation for court admissibility. All samples with a presumptive positive in Screening necessitate a secondary confirmation.
If a sample shows a presumptive positive in Screening, additional hair is taken from the original sample for Extraction. Here, drugs are extracted from hair at much lower levels than other methods (e.g., urine or oral fluid), making hair drug testing the most complex method to execute.
Confirmation of any positive screening outcomes is accomplished via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens are cleaned before confirmation if necessary. The entire lab procedure, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Note: Though often named "hair follicle tests," the analysis examines the hair strand rather than the hair follicle underneath 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.
