Recently, hair follicle drug tests have become a popular method for drug testing. Many employers, courts, and substance abuse specialists prefer it over standard urine tests. These tests are favored by employers with strict drug policies, courts, and for individuals on probation. The main advantage is a longer detection period, typically up to 90 days, with observed collection and minimal cheating risk.

Hair testing has emerged as an effective method for identifying substance and alcohol consumption. Hair offers an extended timeline of alcohol and drug history by embedding biomarkers within the fibers of the growing hair strand. When acquired near the scalp, hair can reveal up to a nearly 3-month detection period for alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and convenient for shipping.
A 1.5-inch segment comprising roughly 200 strands of hair (comparable to the girth of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample quantity for assessment and verification. For EtG, supplementary tests, and/or evaluations exceeding 10 panels, 150mg of the sample is advocated. It is advisable to measure the sample using a jeweler’s scale. If scalp hair is inaccessible, an equivalent quantity of body hair can be obtained. References to head hair pertain only to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The principal phases in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning incorporates the primary handling of a sample within a lab’s framework. This process ensures the sample’s proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data input not covered by an electronic chain of custody system.
Screening entails an initial swift evaluation for drugs of abuse. Although Screening is an economical method for excluding drug usage in most samples, a positive screen must be validated to be acceptable in court. Any samples indicating presumptive positivity during Screening necessitate secondary confirmation.
If a sample indicates presumptive positivity at the Screening stage, additional hair is extracted from the initial sample and prepared for Extraction. During this phase, drugs are isolated from hair at significantly lower concentrations than in alternative methodologies (ex. urine or oral fluid), explaining why hair drug screening is the most challenging methodology to execute.
Confirmation of any positive screening result is performed via GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples are cleansed before confirmation as required. The comprehensive lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

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.
