Lately, hair follicle drug tests are favored for drug screening by various stakeholders like employers and courts, overtaking urine tests. Companies with zero-tolerance policies, as well as legal bodies and probation entities, choose them due to their extensive drug detection window—up to 90 days—and reliable, supervised collection process. However, urine tests still excel in identifying recent usage within 5 days.

Hair testing is recognized as a robust method for identifying drug and alcohol consumption. It offers an extended timeline of drug use by securing biomarkers within the strands as hair develops. Sampling hair near the scalp can reveal a drug and alcohol intake history spanning approximately 90 days. This form of testing is straightforward to conduct, hard to tamper with, and simple to ship.
A 1.5-inch section of roughly 200 hair strands (approximately the diameter of a #2 pencil) close to the scalp yields 100mg of hair, the perfect amount for analysis and verification. For EtG extensions or tests exceeding 10 panels, 150mg of hair is advised. It is recommended to weigh the specimen with a jeweler’s scale. If scalp hair is not obtainable, an identical quantity of body hair can be gathered. When specifying head hair, we mean scalp hair exclusively. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory workflow for drug test evaluation includes four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample into a lab's system. It involves validating the sample's proper sealing and shipping, allotting a random LAN (Laboratory Accessioning Number), and completing any missing data entry that is not captured by an electronic chain of custody system.
Screening refers to an initial and quick assessment for substance abuse. While it is a cost-efficient method to exclude drug usage from most samples, a positive result must be verified to be lawful. Samples indicating presumptive positivity during Screening necessitate a follow-up confirmation.
Should a sample show a presumptive positive in Screening, additional hair is drawn from the original sample for Extraction. During this stage, drugs are retrieved from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening a challenging technique to execute.
Verification of positive screening outcomes is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation as required. The entire lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair categorization and the ISO / IEC 17025 standard accreditation.
Advantages of hair drug testing:
Limitations:
Note: Though often termed as "hair follicle tests", the analysis focuses on the hair strand, not 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.
