Hair analysis is increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair captures a comprehensive history of drug and alcohol markers by embedding them within the fibers of the hair strand as it grows. When acquired near the scalp, hair can offer a detection period of up to roughly 90 days for various substances. The collection process is straightforward, alterations are challenging, and it’s easy to transport.
A 1.5-inch hair portion containing approximately 200 strands (about the width of a #2 pencil) next to the scalp yields 100mg, which is considered optimal for testing and confirmation. For tests including EtG, add-ons, and those exceeding 10 panels, 150mg of hair is preferable. It’s advisable to measure using a jeweler’s scale. In cases where scalp hair cannot be procured, an equivalent quantity of body hair is acceptable. When we refer to head hair, we specifically mean scalp hair. Body hair denotes all other types, including facial and underarm hair.
Process Overview
The drug testing process in a laboratory includes these key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial intake of a sample into a lab’s system. This phase involves ensuring the sample’s proper sealing and transport, assigning a random LAN (Laboratory Accessioning Number), and completing any missing data unless already included by an electronic chain of custody system.
Screening is a preliminary examination for substance misuse. Although it’s an economical approach for eliminating drug use in most cases, further verification is essential for legal admissibility in the event of a positive result. Samples deemed presumptively positive in Screening necessitate additional verification.
For samples showing presumptive positivity during Screening, extra hair is extracted from the original sample and readied for Extraction. Drugs are isolated from the hair at concentrations significantly lower than in other testing methods (like urine or oral fluid), underscoring the complexity of hair drug tests.
Any sample with a positive screen is confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples that show presumptive positivity are cleansed before confirmation if required. The full laboratory process from Accessioning through Confirmation undergoes review under CAP (College of American Pathologists) Hair designation alongside ISO / IEC 17025 accreditation.

Note: While frequently dubbed as "hair follicle tests", the examination actually assesses the hair strand and not the follicle under 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.
