A minimum hair length of 1.5 to 2 inches from the crown or body is necessary for effective testing in many scenarios. These tests are available for drugs, alcohol/ETG, or can be customized for specific needs.
Hair follicle drug testing has gained popularity in recent years for drug screening. Many employers, judicial systems, and substance abuse experts prefer this method over traditional urine tests. Hair tests are favored by zero-tolerance employers, the judiciary, and those on probation due to their longer detection window—up to 90 days—offering a nearly tamper-proof solution. However, for drug use detection within 5 days, urine tests remain more precise.

Hair analysis is increasingly regarded as a potent method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug use by embedding biomarkers within the strands of growing hair. Collected from near the scalp, hair samples can reveal a detection timeframe extending up to roughly 3 months for both alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and convenient for transportation.
A sample measuring 1.5 inches, comprising roughly 200 hair strands (comparable to a #2 pencil in thickness) nearest to the scalp, yields 100mg of hair—this is the optimal sample size for preliminary tests and confirmations. For EtG, additional analyses, and/or assessments surpassing 10 panels, a 150mg specimen is suggested. Utilizing a jeweler’s scale to weigh the specimen is advisable. Should scalp hair not be accessible, a proportional quantity of body hair can be gathered. When mentioning head hair, we exclusively mean scalp hair, while body hair denotes any other types (such as facial, axillary, etc.).
Process Overview
The drug test laboratory operation encompasses four fundamental steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial handling of a sample into the lab's system. This process entails verifying proper sealing and shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry not included by an electronic chain of custody system.
Screening represents a preliminary fast assessment for drugs of abuse. Although Screening is an economical approach to discard drug use in most samples, any positive result requires confirmation to be accepted in legal settings. Any samples showing a presumptive positive during Screening need an additional confirmation.
Should a sample exhibit a presumptive positive during Screening, extra hair is extracted from the initial specimen for the Extraction phase. In Extraction, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), indicating why hair drug screening remains the most challenging methodology to execute.
Confirmation of any positive screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo pre-confirmation washing as deemed necessary. The comprehensive laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the compliance with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although termed as "hair follicle tests", the examination analyzes the hair strand, not the follicle beneath the scalp.

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.
