In recent times, the hair follicle drug test has become a more prevalent technique for drug screening. Employers, judicial systems, and substance abuse counselors often prefer the hair test over traditional urine tests. Employers with strict drug policies, judicial bodies, and probation officers employ hair testing for its extensive detection window, covering up to 90 days. While it offers an observed collection process that makes cheating highly unlikely, urine tests remain more precise for use detection within the past five days.

Hair testing is widely recognized as an effective method for detecting drug and alcohol consumption. Hair acts as a long-term record for alcohol and substances by capturing biomarkers within the fibers of the hair strand as it grows. When taken from near the scalp, hair offers around a 3-month detection period for alcohol and substances. Hair collection is straightforward, relatively hard to tamper with, and convenient for transport.
A sample size of 1.5 inches consisting of approximately 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, which is ideal for testing and verification. For EtG, additional tests, and/or panels over 10, it is advisable to use 150mg of the sample. We suggest using a jeweler’s scale to weigh the sample. If scalp hair is not available, a similar quantity of body hair can be used. By head hair, we mean only scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The primary four steps in the laboratory processing of a drug screening result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the sample’s initial entry into the lab’s system. This step involves ensuring the sample was correctly sealed and shipped, assigning a random Laboratory Accessioning Number (LAN), and completing any data entry missing from an electronic chain of custody system.
Screening is a preliminary check for substance abuse. While Screening is a budget-friendly way to dismiss drug usage in most cases, a positive screen must be validated to stand in court. Any samples with a presumptive positive result in Screening need additional confirmation.
For samples that are presumptively positive during Screening, extra hair is taken from the initial sample and prepared for Extraction. Here, drugs are removed from hair at a much lower concentration than other methods (e.g., urine or oral fluid), explaining why hair drug screening is considerably challenging.
Confirmation for any positive screening result is done using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing before confirmation as needed. The complete laboratory procedure from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Note: Although often termed as "hair follicle tests", the analysis focuses on the hair strand and not the hair follicle beneath the scalp.

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.
