Typically, 1.5 to 2 inches of head or body hair can be used. Tests can detect drugs, alcohol/ETG or can be tailored for other specific testing needs.
Modern drug testing approaches have increasingly embraced hair follicle drug tests. Numerous employers, judicial systems, and substance abuse experts are opting for hair tests in place of standard urine tests. These tests are popular among employers with strict no-drug policies, courts, and for those on probation. A key advantage of hair follicle drug tests is their extended detection period, which generally lasts up to 90 days, with an observed sample collection method that is difficult to manipulate. However, urine tests remain the most reliable for detecting recent drug use within the last five days.

Hair testing is increasingly recognized as an effective approach for identifying drug and alcohol use. Hair encases biomarkers within the fibers as it grows, offering long-term insights into alcohol and drug consumption. When taken near the scalp, hair can reveal alcohol and drug usage for roughly three months. Collecting hair is straightforward, tampering is challenging, and it is easily transported.
A 1.5-inch segment of around 200 hair strands (similar in thickness to a #2 pencil) from near the scalp provides 100mg, the perfect amount for analysis. For EtG, additional tests, or tests exceeding 10 panels, 150mg is advised. It is suggested to weigh the sample using a jeweler's scale. If scalp hair is not an option, an equivalent quantity of body hair may be used. Head hair refers exclusively to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The four essential stages in lab processing of a drug result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the initial setup of a sample within a lab's framework. This step includes checking that the sample was correctly sealed and delivered, assigning a LAN (Laboratory Accessioning Number), and filling in any further data entry that an electronic custody system might lack.
Screening acts as a preliminary check to identify potential drug use. While Screening is cost-efficient for ruling out drug use in most samples, confirmed results are required for courtroom acceptance. Samples that are initially positive in Screening must undergo further confirmation.
Should a sample appear positive at the Screening stage, additional hair is taken from the original sample for Extraction. During Extraction, drugs are separated from hair at much lower concentrations than in other tests like urine or oral fluid, highlighting the complexity of hair drug testing.
Confirmation of any positive results from Screening involves GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positives are cleansed before confirmation if necessary. The entire lab workflow from Accessioning to Confirmation is audited under CAP (College of American Pathologists) Hair accreditation and ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: The term "hair follicle tests" is misleading, as the examination focuses on the hair strand rather than 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.
