Recently, hair follicle drug testing has become more prevalent. Employers, legal bodies, and substance abuse professionals now favor hair tests over urine tests. Employers with zero-tolerance, courts, and probationers utilize hair tests for their benefits, such as a longer detection window of up to 90 days, an observed collection reducing cheating, while urine tests remain best for recent drug use within 5 days.

Seen as an effective method, hair testing excels in identifying drug and alcohol consumption. The fibers of a growing hair strand secure biomarkers, offering a long-term record of alcohol and drug usage. When cut close to the scalp, hair can reveal drug and alcohol use histories dating back up to about three months. Hair collection is straightforward, hard to falsify, and convenient to transport.
A sample of 1.5 inches, comprising roughly 200 hair strands (comparable to a #2 pencil), taken nearest to the scalp, yields 100mg—the preferred quantity for both screening and confirmation. For EtG, extra tests, and/or panels exceeding 10, a 150mg specimen is favored. Utilizing a jeweler’s scale for specimen weighing is advisable. If scalp hair is absent, an equivalent portion of body hair can be gathered. "Head hair" pertains exclusively to scalp hair, whereas "body hair" encompasses all other hair types (like facial, axillary, etc.).
Process Overview
The key stages in processing a lab drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage, where a sample is processed into a lab’s system, ensuring proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any data entry not captured by an electronic chain of custody.
Screening is a preliminary assessment for substance abuse. Although Screening is a cost-effective method to exclude drug use on most samples, a positive test requires confirmation for legal admissibility. Presumptive positives in Screening necessitate further verification.
If a sample tests presumptively positive during Screening, additional hair is retrieved from the original specimen for Extraction. This phase involves extracting drugs at lower concentrations than other methodologies (like urine or oral fluid), making hair drug screening a complex methodology.
GC/MS, GC/MS/MS, or LC/MS/MS methods confirm any positive screening outcomes. All presumptive positive samples undergo washing before Confirmation if needed. The entire procedural process from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly termed as "hair follicle tests", the examination actually evaluates the hair strand, not the 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.
