Hair tests have become recognized as an essential method for spotting the use of drugs and alcohol. Hair offers a prolonged history of alcohol and drug usage by holding biomarkers in the fibers of the expanding hair strand. When taken near the scalp, hair can allow a roughly 3-month detection period for alcohol and drugs. Collecting hair is straightforward, relatively tough to tamper with, and simple to transport.
A 1.5-inch specimen of around 200 hair strands (comparable to the width of a #2 pencil) nearest to the scalp will produce 100mg of hair, which is the prime sample for testing and verification. For EtG, additional assays, and/or screens surpassing 10 panels, 150mg of the sample is advised. We suggest measuring the sample on a jewelry balance. If scalp hair isn't obtainable, the same quantity of body hair can be used. When indicating head hair, we are referring solely to scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).
Process Overview
The key stages in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial handling of a sample into a lab’s system. This process includes ensuring the sample was correctly sealed and shipped, assigning it a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry not included by an electronic chain of custody system.
Screening consists of an initial rapid assessment for substance misuse. While Screening is a cost-effective method to dismiss drug consumption in many cases, a positive screen must be verified to hold up in court. Samples that test presumptively positive in Screening require a secondary confirmation.
If a specimen tests presumptively positive in the Screening phase, additional hair is extracted from the original sample and prepared for Extraction. In this phase, drugs are extracted from hair at a considerably lower concentration than other methods (such as urine or oral fluid), concluding hair drug screening as the most challenging method to execute.
Confirmation of any positive Screening result is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptively positive specimen is cleansed before confirmation if necessary. The full lab process from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: While often labeled as "hair follicle tests", the test itself examines the hair strand and not the hair 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.
