Recently, hair follicle drug testing has become more popular over traditional methods. Companies, courts, and substance abuse experts often prefer hair tests to standard urine tests. Hair follicle drug tests are mandatory for employers with zero-tolerance policies, courts, and individuals on probation. The advantage of these tests lies in their extended detection window—up to 90 days—and their difficulty to tamper with, although urine tests remain more accurate for detecting recent drug use within five days.

Hair testing is recognized as a robust method for detecting drug and alcohol consumption. It captures long-term substance use history by embedding biomarkers in the hair's growing fibers. When gathered near the scalp, hair can reveal a detection period of up to around three months for substances. Hair collection is straightforward, relatively tamper-resistant, and simple to transport.
A 1.5-inch segment containing approximately 200 hair strands (equivalent in width to a #2 pencil) nearest the scalp provides 100mg, an optimal sample size for screening and confirmation processes. For tests like EtG, addons, and panels exceeding 10, 150mg of hair is advisable. We suggest weighing samples using a jeweler's scale. In the absence of scalp hair, a comparable amount of body hair can be obtained. 'Head hair' refers to only scalp hair in this context, while 'body hair' encompasses all other forms (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where a sample is integrated into the laboratory system. It comprises checking that the sample is properly sealed and shipped, assigning a LAN (Laboratory Accessioning Number) randomly, and finishing any additional data entry absent in an electronic chain of custody system.
Screening is a preliminary evaluation for substance abuse. Though economical for negating drug use in most samples, positive screenings must be confirmed to hold up in court. Samples with tentative positive results in Screening require further confirmation.
For samples with a presumptive positive result, more hair is taken from the initial sample for the Extraction process. At this stage, drugs are removed from the hair at a significantly lower concentration compared to other methods (like urine or oral fluid), making hair drug screening the most challenging method to execute.
Confirmation for any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples flagged as presumptively positive are washed before confirmation if necessary. The complete laboratory procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Though commonly termed as "hair follicle tests", these tests examine the hair strand, not the follicle beneath the scalp.

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.
