Over recent years, hair follicle drug tests have gained prominence in drug testing procedures. Many professionals, such as employers, courts, and substance abuse experts, prefer them over standard urine tests. Organizations with zero-tolerance policies, court systems, and individuals on probation commonly use these tests due to their extended detection period of up to 90 days. They involve an observed collection process, minimizing cheating risks. Nonetheless, urine tests remain the best for recent drug use detection within five days.

Hair testing has emerged as a significant method for identifying drug and alcohol consumption. Hair retains a long-term record of alcohol and drug use by capturing biomarkers in the fibers of the hair strand as it grows. When harvested near the scalp, hair can offer up to a 3-month detection span for alcohol and various drugs. The collection process for hair is straightforward, relatively challenging to tamper with, and convenient to transport.
A sample size of 1.5 inches, consisting of roughly 200 hair strands (comparable to a #2 pencil's diameter), will provide 100mg of hair, which is ideal for screening and confirming. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the hair sample is advised. It is recommended to weigh the sample using a jeweler's scale. If scalp hair cannot be collected, an equal quantity of body hair may be used. When head hair is mentioned, it specifically means scalp hair. Body hair includes all other hair types (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the primary step of entering a sample into a lab’s system. This step includes ensuring the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any supplemental data entry absent from an electronic chain of custody system.
Screening encompasses an initial quick test for substances of abuse. Though Screening offers a cost-effective method to negate drug use in most samples, a court-admissible result requires confirmation of a positive screen. Samples showing presumptive positive results in Screening warrant additional confirmation.
If the Screening stage indicates a presumptive positive result, additional hair is extracted from the original sample and prepared for Extraction. During this phase, drugs are extracted from the hair at a substantially lower concentration than in other methods (e.g., urine or oral fluid), which contributes to the complexity of hair drug screening.
Confirmation of a positive screen result is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive findings undergo washing before confirmation as required. The complete lab procedure, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.

Limitations:
Note: Though commonly called "hair follicle tests", the test itself focuses on analyzing 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.
