Hair analysis is now widely regarded as an effective method for discovering drug and alcohol consumption. Hair acts as a historical record of substance use by capturing biomarkers within the fibers of the hair as it grows. When obtained near the scalp, hair can reveal drug and alcohol usage for up to a 3-month period. The collection process is straightforward, altering the sample is relatively challenging, and it is easy to send for analysis.
A 1.5-inch portion, approximately 200 strands of hair, comparable in size to a #2 pencil, gathered nearest to the scalp, provides 100mg of hair—the perfect amount for testing and verification. For EtG, additional tests, or tests exceeding 10 panels, it is advisable to use 150mg of the sample. Utilizing a jeweler’s scale is recommended for weighing the sample. If scalp hair cannot be obtained, the same amount of body hair can be used. When mentioning head hair, it specifically means scalp hair. Body hair denotes all other forms (facial, axillary, etc.).
Process Overview
The key phases of processing a drug test in the lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the preliminary handling of a sample in a lab’s framework. It verifies the proper sealing and shipping of the sample, assigns a unique LAN (Laboratory Accessioning Number), and concludes any supplementary data input missing from an electronic custody chain system.
Screening serves as a rapid initial test for detecting drug abuse. While it’s a cost-effective method for the majority of samples, any positive findings require further confirmation for legal acceptability. Samples testing positive in Screening necessitate additional confirmation.
Should a sample test positive in Screening, additional hair is extracted from the sample for the Extraction process. Here, substances are isolated from hair at considerably lower concentrations compared to other methods (such as urine or oral fluid), rendering hair drug screening particularly complex.
Any screening results that test positive undergo confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All potentially positive samples are cleansed prior to confirmation as required. The entire lab procedure from Accessioning to Confirmation is audited according to both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.

Limitations:
Note: Often termed as "hair follicle tests," the procedure targets hair strands rather than the follicles beneath the scalp.

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.
