Hair testing is recognized as an effective method for detecting the use of drugs and alcohol. Hair retains a history of alcohol and drugs over a prolonged period by embedding biomarkers in the fibers of the hair strand. When taken near the scalp, hair can offer an approximate three-month detection period for alcohol and various drugs. Hair collection is straightforward, tough to tamper with, and easy to send.
A sample of 1.5 inches consisting of around 200 hair strands (comparable to the width of a #2 pencil) nearest to the scalp will yield 100mg of hair, serving as the optimal quantity for both screening and confirmation. For EtG, add-ons, and/or tests that exceed 10 panels, 150mg of the specimen is suggested. It's advisable to weigh the specimen using a jeweler's scale. If scalp hair isn't present, an equivalent quantity of body hair can be gathered. In reference to head hair, this implies only scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The essential stages in processing a drug test result in a lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial processing of a sample in a lab’s system. This involves ensuring the sample was properly sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody system.
Screening entails a preliminary quick assessment for drugs of abuse. Although Screening is an economical way to exclude drug use in most samples, a positive screen must be confirmed before it can be accepted in a legal setting. Samples that appear positive in Screening certainly require a follow-up confirmation.
In cases where a sample tests positive in the Screening phase, additional hair is taken from the initial specimen and readied for Extraction. At this point, drugs are extracted from hair at a notably lower concentration than alternative methods (e.g., urine or oral fluid), marking hair drug screening as the most challenging method to execute.
The Confirmation of any positive result from screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptive positive undergo washing prior to confirmation as necessary. The full laboratory sequence from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and aligned with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly called "hair follicle tests", this test examines the hair strand rather than the scalp's hair follicle.

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.
