In the last few years, hair follicle testing has gained favor in drug testing methods. Many employers, judicial entities, and substance abuse experts now opt for hair drug tests over traditional urine tests. This method is preferred by employers with no-drug policies, courts, and for those on probation. Hair follicle tests offer an extended detection window for drug use, typically up to 90 days, with an observed collection process that is hard to manipulate. Meanwhile, for assessing drug use within the past 5 days, urine tests remain the most precise.

The analysis of hair has become recognized as an effective means to identify the consumption of drugs and alcohol. Hair retains a comprehensive record of substances including alcohol by holding onto biomarkers within the strands' fibers as they grow. When cut near the scalp, hair can offer up to a three-month detection period for these substances. Its collection is straightforward, it’s relatively tamper-resistant, and easy to transport.
A 1.5-inch segment of roughly 200 hair strands (about the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is optimal for analysis. For EtG and expanded tests beyond 10 panels, 150mg is recommended. It is advisable to weigh the hair on a jeweler's scale. If no scalp hair is present, a similar quantity of body hair can be utilized. "Head hair" specifically refers to scalp hair, while "body hair" encompasses other types (facial, axillary, etc.).
Process Overview
The key phases in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially entered into the laboratory system. This phase checks if the sample is properly sealed and shipped, assigns it a unique LAN (Laboratory Accessioning Number), and completes any remaining data entry not covered by an electronic chain of custody.
Screening is an initial rapid assessment for substance misuse. While Screening is cost-efficient for negating drug usage in most samples, a positive result requires validation to be court-admissible. Samples that are considered positive during Screening must undergo further confirmation.
Should a sample be presumptively positive at Screening, additional hair is extracted from the original sample for Extraction. During Extraction, substances are removed from hair at much lower levels than other methods (like urine or saliva), which makes hair drug testing particularly challenging.
The Confirmation phase of any presumptive positive result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Every sample deemed presumptively positive is washed before Confirmation if necessary. The full lab process from Accessioning to Confirmation is governed under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 standards.

Drawbacks:
Note: While commonly referred to as "hair follicle tests", the analysis targets 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. As we embrace these advancements, we pave the way for a safer, healthier society, where drug testing and analysis serve as powerful tools in protecting public health and maintaining integrity in various sectors. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.
