Hair testing is increasingly recognized as an effective method for identifying drug and alcohol use. The long-term history provided by hair arises from its ability to capture biomarkers in its growing strands. A sample taken near the scalp can reflect drug and alcohol usage for up to about three months. Collecting hair is straightforward, relatively tamper-proof, and easy to transport.
A 1.5-inch section containing roughly 200 hair strands (about the diameter of a #2 pencil) taken near the scalp usually yields 100mg, which is the optimal amount for screening and confirmation. For EtG, additional analyses, or tests exceeding 10 panels, a sample of 150mg is advised. It's beneficial to weigh the sample using a jeweler’s scale. If scalp hair cannot be obtained, body hair in an equivalent amount can be used. When mentioning head hair, it refers solely to scalp hair. All other hair types (facial, axillary, etc.) are classified as body hair.
Process Overview
There are four primary phases in the lab processing of drug tests: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of processing a sample within a lab's system, which involves confirming that the sample is correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data input not provided by an electronic chain of custody system.
Screening consists of a quick preliminary evaluation for drug abuse. While Screening economically eliminates negative results in most cases, any positive detected requires confirmation for it to be legally admissible. Any samples flagged as presumptive positive in Screening need further confirmation.
Should a sample show a presumptive positive in the Screening phase, additional hair from the original sample is used for Extraction. During Extraction, drugs are extracted from hair at much lower concentrations than other methods (e.g., urine or oral fluid), which accounts for hair drug testing's complexity.
Confirmation for positive screening outcomes employs methods such as GC/MS, GC/MS/MS, or LC/MS/MS, with presumptive positive samples washed before confirmation as necessary. The comprehensive lab procedure from Accessioning to Confirmation is conducted under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Despite the frequent label "hair follicle tests", this test examines 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.
