Lately, hair follicle drug assessments have become more commonplace in testing procedures. Employers, legal bodies, and substance abuse experts are opting for hair-based evaluations over regular urine tests. Ideal for zero-tolerance policies, judicial mandates, and probationary checks, hair follicle tests offer a detection window of up to 90 days, quase impossible to manipulate, albeit urine tests remain superior for detecting recent use within a 5-day window.

Hair testing is now recognized as an effective method for detecting drugs and alcohol. By embedding biomarkers within the growing strands, hair provides a comprehensive history of substance use. When gathered near the scalp, it offers about a 3-month timeframe for identifying alcohol and other substances. Hair collection is straightforward, hard to tamper with, and convenient for sending.
A sample measuring 1.5 inches with approximately 200 hair strands (roughly the thickness of a #2 pencil) from the scalp will supply 100mg of hair, which is ideal for screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, 150mg is advisable. Utilizing a jeweler’s scale for weighing is suggested. Should scalp hair be lacking, a similar quantity of body hair can be used instead. When mentioning head hair, we specifically mean scalp hair. Conversely, body hair includes various kinds of hair (facial, axillary, etc.).
Process Overview
There are four primary stages in the laboratory handling of drug test samples: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial step where a sample is registered into the lab's system. This step ensures the sample's proper sealing and shipment, allocates it a unique LAN (Laboratory Accessioning Number), and completes any missing information not captured by electronic chain of custody systems.
Screening is the preliminary assessment to detect substances of abuse. Although Screening is cost-effective for deducing drug absence in most samples, any positive findings require confirmation for legal validity. Samples appearing positive during Screening undergo further verification.
In cases where Screening suggests a positive result, additional hair from the sample is used for the Extraction stage. In this phase, substances are isolated from hair at concentrations much lower than those in other methods (e.g., urine or oral fluid), making hair drug screening one of the most challenging procedures.
Confirming any positive Screening is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. All potential positive samples are cleansed before confirmation if necessary. The complete lab process from Accessioning to Confirmation adheres to standards set by the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although known as "hair follicle tests", these assessments analyze the hair strand, not the actual 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.
