Hair analysis has emerged as an effective method for uncovering drug and alcohol consumption. The strands trap biomarkers within their fibers, offering an extended history of substance and alcohol use. When clipped near the scalp, these strands can reveal up to a roughly 90-day timeframe for substances. Hair collection is straightforward, somewhat resistant to tampering, and straightforward to transport.
A sample of 1.5 inches, consisting of approximately 200 hair strands (comparable to the thickness of a #2 pencil) closest to the scalp provides 100mg of hair, the optimal quantity for both initial and confirmatory analysis. For EtG analyses, additional tests, or more than 10-panel tests, a hair specimen weighing 150mg is suggested. It is advisable to measure the sample using a jeweler’s balance. If scalp hair isn't available, an equivalent quantity of body hair can be used. References to head hair pertain to scalp hair exclusively. Body hair encompasses all other types, such as facial and axillary.
Process Overview
The process of processing a drug test result in the lab consists of four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial entry of a sample into the laboratory’s records. This step verifies the sample's sealing and proper shipment, assigns a random Laboratory Accessioning Number (LAN), and completes any supplementary data entries that aren't provided by an electronic chain of custody system.
Screening provides a preliminary and rapid assessment for substances of abuse. Though cost-effective for negating drug usage in most samples, a positive screening needs confirmation to be legally defensible. Any samples with positive indications during Screening require further confirmation through a secondary process.
Should a sample indicate positive results during the Screening phase, additional hair from the initial sample is extracted for the Extraction process. Here, substances are isolated from hair at concentrations significantly lower than those in other procedures, such as urine or oral fluid, making hair drug analysis the most intricate methodology to execute.
The Confirmation stage for any positive screening result employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumed positive samples are washed if necessary before Confirmation. The entire laboratory procedure, from Accessioning to Confirmation, is assessed under the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Despite being termed as "hair follicle tests", the analysis focuses on the hair strand rather than the follicle itself beneath the surface.

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.
