Recently, the inclusion of hair follicle drug testing has become more prevalent in drug testing methods. Hair drug tests are now favored by employers, courts, and Substance Abuse experts over standard urine tests. Employers enforcing zero-tolerance policies, judicial systems, and probation subjects utilize hair follicle tests for their extended detection period up to 90 days. Nevertheless, urine tests remain the most precise for detecting drug use within the past five days.

Hair testing has gained recognition as an effective method for identifying drug and alcohol usage. Hair offers an extended history of alcohol and drugs by encapsulating biomarkers within the strands of growing hair. When sampled near the scalp, hair can offer up to a 3-month period for detecting alcohol and drugs. Collection of hair is straightforward, relatively resistant to tampering, and simple to transport.
A sample measuring 1.5 inches with about 200 hair strands (approximately the width of a #2 pencil) nearest the scalp yields 100mg, which is the preferred sample size for analysis and validation. For EtG, additional tests, and/or panels over 10, 150mg of the sample is advised. It's suggested to weigh the sample using a jeweler’s scale. If scalp hair isn't available, a corresponding amount of body hair can be utilized. The term 'head hair' specifically refers to scalp hair. 'Body hair' encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test outcome involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where the sample is processed into the laboratory's system. This step includes verifying proper sealing and shipment of the sample, assigning a LAN (Laboratory Accessioning Number) at random, and completing any supplementary data entry not covered by an electronic chain of custody system.
Screening is a preliminary assessment for drugs of abuse. While Screening is an economical means to rule out drug usage in most samples, a positive result at this stage must be verified for court acceptance. Any presumptively positive samples in Screening require further confirmation.
Should the sample test presumptive positive in Screening, additional hair is taken from the initial sample and readied for Extraction. This stage involves the extraction of drugs from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most complex methodology.
Confirmation of any positive result from Screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples testing presumptive positive undergo washing before confirmation if necessary. The full lab procedure, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation alongside ISO / IEC 17025 standards accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests", the analysis actually involves the hair strand, not the follicle beneath the scalp.

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.
