Hair testing is widely acknowledged as a potent method for identifying drug and alcohol consumption. By embedding biomarkers in the hair's growing strand fibers, hair offers a comprehensive account over an extended period. When procured near the scalp, it provides up to an approximately 3-month detection range for alcohol and other drugs. Hair collection is straightforward, hard to tamper with, and convenient to transport.
A sample measuring 1.5 inches, comprising approximately 200 hair strands (equivalent to the width of a #2 pencil) nearest to the scalp, yields 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, or panels exceeding 10, a specimen of 150mg is advisable. Utilizing a jeweler’s scale to weigh the specimen is recommended. In the absence of scalp hair, a comparable quantity of body hair may be used. The term head hair specifically denotes scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial examination of a sample within a laboratory's framework. This step ensures the sample's proper sealing and shipping, assigns a unique LAN (Laboratory Accessioning Number), and completes any supplementary data entry absent from an electronic chain of custody system.
Screening serves as an initial swift assessment for substances of abuse. Though a cost-effective strategy to eliminate drug usage in most cases, positive screens require confirmation to be valid in legal proceedings. Any specimens with presumptive positive results in Screening must undergo secondary confirmation.
In instances of presumptive positivity at the Screening phase, additional hair is extracted from the initial sample for preparation in the Extraction phase. During this phase, drugs are retrieved from hair at much lower concentrations relative to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging technique to perform.
GC/MS, GC/MS/MS, or LC/MS/MS methods confirm any positive screening results. All samples with presumptive positivity undergo necessary washing before confirmation. The comprehensive laboratory process, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although often labeled as "hair follicle tests," the analysis focuses on 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.
