The utilization of hair testing has gained recognition as a robust method for identifying both drug and alcohol consumption. Hair serves as a retrospective record of substance use by encasing biomarkers within the strands of hair as it grows. When hair is harvested close to the scalp, it can indicate substance use for up to roughly three months for both alcohol and drugs. Hair is straightforward to collect, relatively resistant to tampering, and easy to transport.
An ideal specimen consists of a 1.5-inch segment, equivalent to approximately 200 strands of hair (comparable to the thickness of a #2 pencil) situated nearest to the scalp, yielding 100mg of hair which is optimal for both screening and confirmation. For tests including EtG, add-ons, or those exceeding ten panels, a sample of 150mg is advisable. It is suggested to determine the specimen’s weight using a jeweler’s scale. In the absence of scalp hair, a comparable quantity of body hair can be obtained. "Head hair" refers exclusively to scalp hair, whereas "body hair" encompasses all other types (e.g., facial, axillary).
Process Overview
The laboratory process for analyzing a drug test consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample first undergoes processing in the lab’s system. This involves ensuring that the sample was appropriately sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data input not supplied by an electronic chain of custody system.
Screening represents the initial rapid assessment for drugs of abuse. Although Screening provides a cost-efficient method to eliminate drug use in the majority of samples, a confirmed positive result is necessary for legal considerations. Any samples that test presumptively positive in Screening require additional confirmation.
In cases where a sample tests presumptively positive while in the Screening phase, additional hair is taken from the initial sample and readied for Extraction. During this phase, drugs are retrieved from hair at a significantly reduced concentration compared to other methods (e.g., urine or oral fluid), which is why hair drug screening presents as the most challenging methodology.
To verify positive Screening outcomes, Confirmation is executed employing GC/MS, GC/MS/MS, or LC/MS/MS. Before Confirmation, all presumptive positive samples undergo washing when necessary. The entire laboratory cycle from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair classification and meets the ISO / IEC 17025 licensing standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly labeled as "hair follicle tests", the test actually examines the hair strand, not the follicle under the scalp.
Hair Testing Triumphs Over Urine 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.
