Hair analysis has emerged as a potent means for uncovering alcohol and drug consumption. The strands of hair, during their lifetime, trap biomarkers within the growing fibers, providing a chronicled history of substance use. When collected near the scalp, hair offers insight into up to a three-month detection period for substances. Gathering hair is straightforward, challenging to tamper with, and effortless to transport.
A 1.5-inch hair specimen consisting of around 200 strands (comparable to the size of a #2 pencil) located nearest to the scalp will yield 100mg of hair, which is the optimal amount for both screening and subsequent confirmation. For EtG enhancements, and/or assessments exceeding 10 panels, a specimen weight of 150mg is advised. It's recommended to weigh the specimen using a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair can be used. Reference to head hair pertains strictly to scalp hair. Body hair encompasses any other forms of hair (e.g., facial, axillary, etc.).
Process Summary
There are four principal stages in the lab processing of drug test outcomes: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample into a lab’s system. This phase includes confirming the proper sealing and shipping of the specimen, the allocation of a unique LAN (Laboratory Accessioning Number), and completing any supplementary data inputs absent in an electronic chain of custody system.
Screening is an initial rapid assessment for drugs of abuse. Although Screening is a cost-efficient approach to exclude drug consumption in most cases, a positive result mandates confirmation to hold up in legal proceedings. Any samples presumed positive during Screening necessitate a secondary confirmation.
Upon the event a sample is suspected positive during Screening, more hair is extracted from the initial batch and prepped for Extraction. At this juncture, drugs are isolated from the hair at markedly lower concentrations than with other methodologies (e.g., urine or oral fluid), underscoring the complexity of hair drug analysis.
Every positive screened result is validated through GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptively positive samples undergo washing prior to validation as necessary. The complete laboratory journey from Accessioning to Confirmation is scrutinized in accordance with the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Drawbacks:
Note: Although commonly labeled as "hair follicle tests", the examination is conducted on the hair strand, not the follicle beneath the scalp.

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.
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.
