Generally, a hair length of 1.5 to 2 inches is required, and in many instances, body hair is an alternative. Hair tests can identify drugs, alcohol/ETG, or include other tailored testing options.
In recent times, hair follicle drug tests have increasingly become a staple in drug testing protocols. Many employers, courts, and substance abuse specialists now opt for hair drug tests over traditional urine tests. Hair follicle testing is preferred by employers who enforce zero-tolerance policies, used in court systems, and for individuals on probation due to its extended detection capabilities that span up to 90 days, with observation during sample collection, making it extremely difficult to tamper. Despite this, urine tests remain the most accurate for detecting recent usage within a five-day window.

Hair analysis has emerged as an effective method for detecting drug and alcohol consumption. Hair provides an extended history of substance use by embedding biomarkers in the strands of hair as they grow. When collected near the scalp, hair can deliver up to a 3-month detection period for alcohol and drugs. Hair is easy to collect, resist alteration, and simple to transport.
A sample measuring 1.5 inches with approximately 200 hair strands (comparable to a #2 pencil thickness) near the scalp yields 100mg of hair, ideal for testing and validation. For EtG tests, additional panels, or tests exceeding 10 panels, 150mg of the sample is advised. Using a jeweler’s scale is recommended for weighing the specimen. If scalp hair is not present, a similar amount of body hair might be used. Head hair refers exclusively to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The four primary steps in processing a drug test result in a lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab’s system. This process involves checking that the sample was securely sealed and shipped, assigning it a random LAN (Laboratory Accessioning Number), and completing any outstanding data entry not covered by an electronic chain of custody system.
Screening entails a preliminary inspection for drugs of abuse. While Screening serves as a cost-efficient means to exclude drug use in most samples, a positive result must be verified for court admissibility. Samples that are presumptively positive in Screening require a follow-up confirmation.
If a sample indicates positivity in the Screening stage, extra hair is retrieved from the primary specimen for Extraction. In this stage, drugs are isolated from hair at a considerably lower concentration than through other methods (e.g., urine or oral fluid), which is why hair drug screening is the most challenging technique to perform.
Confirmation of any positive screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positivity are cleansed before confirmation as necessary. The entire lab procedure from Accessioning to Confirmation is surveyed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standard accreditation.

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.
