Recently, hair testing has become recognized as an effective method for detecting the consumption of drugs and alcohol. Hair serves as a long-term record of alcohol and drug exposure by capturing biomarkers within the fibers of the hair as it grows. When collected near the scalp, hair can offer a detection window for alcohol and drugs extending up to around 3 months. Gathering hair samples is straightforward, relatively hard to tamper with, and convenient for shipping.
A sample measuring 1.5 inches consisting of about 200 hair strands (about the diameter of a #2 pencil) close to the scalp provides 100mg of hair, which is the optimal sample size for screening and confirmation. For tests such as EtG, add-ons, or those exceeding 10 panels, 150mg of hair is advisable. It is advised to weigh the hair sample using a jeweler’s scale. If scalp hair cannot be collected, an equivalent quantity of body hair might be used. The term "head hair" refers exclusively to scalp hair. Body hair includes all other hair types such as facial and axillary hair.
Process Overview
The laboratory processing involved in producing a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the preliminary processing of a sample into the laboratory's system, ensuring the sample was appropriately sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry not facilitated by an electronic chain of custody system.
Screening is a quick initial check for illicit drug usage. While Screening offers a cost-effective means to exclude drug use in most samples, a positive Screening result must be confirmed to be valid in legal proceedings. Presumptively positive samples identified during Screening necessitate additional confirmation.
In instances where a sample tests positive during the Screening phase, additional hair is extracted from the initial collection and prepared for Extraction. During Extraction, drugs are isolated from hair at notably lower concentrations compared to other methods (e.g., urine or oral fluid), explaining why hair drug screening is regarded as the most challenging method to execute.
Confirming any positive Screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptively positive samples are washed if needed. Every aspect of the laboratory process, from Accessioning to Confirmation, is scrutinized in line with both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Limitations:
Note: Despite often being called "hair follicle tests", the actual analysis is conducted 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.
