Hair testing is recognized as an effective method for identifying drug and alcohol usage. Hair retains a historical record of alcohol and drugs by capturing biomarkers within the growing hair fibers. A sample collected near the scalp can offer up to a 3-month timeframe for detecting alcohol and drugs. Hair samples are easy to gather, relatively tamper-resistant, and simple to send.
A 1.5-inch portion comprising approximately 200 hair strands (about the width of a #2 pencil) closest to the scalp yields 100mg of hair, an optimal sample size for initial testing and verification. For EtG, additional tests, or analyses beyond 10 panels, a 150mg sample is advisable. Using a jeweler’s scale for weighing the sample is recommended. If scalp hair cannot be obtained, a similar quantity of body hair is acceptable. References to head hair pertain only to scalp hair, while body hair includes all other hair types (e.g., facial, axillary).
Process Overview
The laboratory processing of a drug test result consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with integrating a sample into a laboratory's system. This involves ensuring the sample is properly sealed, assigning a random LAN (Laboratory Accessioning Number), and completing any data entry not covered by an electronic chain of custody.
Screening performs an initial assessment for substances of abuse. It is a cost-efficient method to exclude drug use in most samples, but a positive result requires confirmation for legal acceptability. Samples showing a presumptive positive result in Screening need further verification.
Should the Screening step indicate a potential positive, more hair from the original sample is prepared for Extraction. The drugs are extracted at a significantly lower concentration than in other methods (e.g., urine or oral fluid), which makes hair drug testing the most challenging to conduct.
Positive screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned beforehand as needed. The complete laboratory procedure, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although sometimes called "hair follicle tests", the test examines the hair strand, not the follicle beneath the scalp.

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.
