Hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair captures biomarkers within the fibers of the maturing hair strand, offering a protracted history of alcohol and other drug use. When collected near the scalp, hair can reveal a detection period of up to about 3 months for alcohol and other substances. The collection of hair is straightforward, relatively resistant to tampering, and convenient to transport.
A 1.5-inch piece consisting of 200 hair strands (equivalent to a #2 pencil's width) nearest to the scalp provides 100mg of hair, the optimal quantity for screening and verification. For EtG, additional tests, and/or beyond 10 panels, 150mg of the sample is suggested. Measuring the sample with a jeweler’s scale is advised. If there's no scalp hair, an equivalent volume of body hair can be used. "Head hair" specifically refers to scalp hair. "Body hair" encompasses any other hair types (such as facial, axillary, etc.).
Process Overview
The drug testing lab process comprises four major steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning signifies the initial processing of a sample within a laboratory’s system. This step confirms the sample's proper sealing and shipping, assigns it a random LAN (Laboratory Accessioning Number), and completes any further data not supplied by an electronic chain of custody system.
Screening conducts a preliminary swift check for substance abuse. While it is an economical means to exclude drug use in most samples, positive screens must be verified to hold up legally. Samples presumed positive at Screening necessitate an additional confirmation.
If a sample tests presumptively positive during Screening, additional hair is extracted from the original sample and prepared for Extraction. At this step, drug substances are drawn out from hair at significantly lower concentrations than other methods (for example, urine or oral fluid), rendering hair drug screening the most complex methodology to implement.
Confirmation of any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive outcomes undergo washing before confirmation if required. The comprehensive lab process from Accessioning through Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Limitations:
Note: Though often called "hair follicle tests", the test actually evaluates the hair strand, not the follicle located 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.
