Hair follicle drug tests have gained popularity in recent years as a preferred method for drug screening. This type of test is often chosen by employers, legal authorities, and substance abuse professionals over urine tests. It's favored by employers with zero-tolerance drug policies, courts, and for probation monitoring. A significant advantage of hair testing is its extended detection period of up to 90 days, conducted through an observed process, making it hard to tamper. However, urine tests remain superior for detecting recent drug use within five days.

Acknowledged for its efficiency, hair testing serves as an invaluable method for identifying drug and alcohol consumption. By encapsulating biomarkers within the strands of growing hair, it captures a comprehensive chronicle of substance use. Hair sampled near the scalp offers an approximate detection period of three months for drugs and alcohol. The collection of hair is straightforward, challenging to tamper with, and convenient to transport.
For optimal analysis, a 1.5-inch segment consisting of around 200 hair strands (comparable to the width of a #2 pencil) should be sourced near the scalp, providing 100mg, the preferred amount for both testing and validation. When considering EtG, additional tests or panels exceeding ten, a 150mg sample is advisable. It is suggested to measure the sample using a jeweler’s scale. In instances where scalp hair is unobtainable, an identical quantity of body hair might be utilized. References to head hair exclusively pertain to scalp hair, whereas body hair signifies all other categories (such as facial or axillary).
Process Overview
The laboratory processing of a drug test result includes four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is integrated into a laboratory’s system. This entails confirming the proper sealing and shipment of the sample, generating a random LAN (Laboratory Accessioning Number), and entering any supplementary data not specified by an electronic chain of custody protocol.
Screening constitutes a preliminary evaluation for drugs of abuse. It is a cost-effective measure to exclude drug use across most samples; however, a positive screening result must be verified to be permissible in legal proceedings. All samples with an initial positive indication during Screening require further confirmation.
Should a sample exhibit a presumptive positive during Screening, more hair is extracted from the original sample to be prepped for Extraction. During Extraction, drugs are isolated from hair at a notably lower concentration compared to other methods like urine or oral fluid testing, underscoring the complexity of hair drug screening.
The Confirmation process for any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Prior to confirmation, all presumed positive samples undergo necessary washing. From Accessioning through Confirmation, the entire laboratory procedure is scrutinized under the CAP (College of American Pathologists) Hair designation alongside ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although often termed "hair follicle tests", the analysis targets the hair strand above the scalp, not the follicle.

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.
