Over the last few years, hair follicle drug tests have become a common method of drug testing. Many employers, courts, and Substance Abuse professionals prefer hair drug tests over traditional urine tests. Employers with strict no-drug policies and courts frequently use these tests. Key advantages include a longer detection period, often up to 90 days, observed collection, and reduced likelihood of cheating. However, for detecting recent drug use within 5 days, urine tests remain the most precise.

Hair testing has emerged as a robust method for detecting drug and alcohol consumption. Hair encapsulates a comprehensive timeline of alcohol and drug use by embedding biomarkers within the fibers of the hair as it grows. When hair is collected near the scalp, it can offer a detection period of up to roughly 3 months for alcohol and drugs. Hair is easy to collect, relatively hard to tamper with, and straightforward to transport.
A 1.5-inch portion of approximately 200 hairs (roughly the size of a #2 pencil) closest to the scalp yields 100mg of hair, which is the perfect quantity for both screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, 150mg is suggested. Measuring the specimen on a jeweler’s scale is advisable. Should scalp hair be unavailable, an equivalent amount of body hair can be collected. When we mention head hair, we mean scalp hair exclusively. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a laboratory's system. This process includes ensuring that the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not available through an electronic chain of custody.
Screening is an initial rapid assessment for drugs of abuse. While Screening is a cost-efficient means to eliminate drug use across most samples, a positive result must be confirmed for court admissibility. Samples that are presumptively positive during Screening need a follow-up confirmation.
Should a sample test presumptively positive in the Screening phase, additional hair is taken from the initial sample and readied for Extraction. In this phase, drugs are extracted from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening one of the most challenging methods.
Confirmation of any positive screening finding is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The full laboratory procedure from Accessioning to Confirmation is reviewed under the CAP (College of American Pathologists) Hair standards and accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly termed as "hair follicle tests", the actual test analyzes the hair strand rather than 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.
