Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair captures biomarkers within its fibers, offering a long-term history of substance use. When taken near the scalp, hair samples can reveal drug or alcohol use over a period of up to three months. Hair samples are easy to gather, challenging to tamper with, and straightforward to transport.
A sample measuring 1.5 inches and consisting of around 200 hair strands, similar in diameter to a #2 pencil, yields about 100mg of hair, which is optimal for both screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, a sample weighing 150mg is advised. Using a jeweler’s scale to weigh the specimen is recommended. Should scalp hair be unavailable, collecting an equal measure of body hair is acceptable. References to head hair are specifically about scalp hair, while body hair includes other types such as facial and axillary hair.
Process Overview
The laboratory processing of a drug test result encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into the laboratory's system, ensuring it was sealed and sent correctly, assigning it a random LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody system.
Screening performs a preliminary, rapid evaluation for drugs of abuse. Although Screening is an economical method to rule out drug usage for most samples, a positive result requires confirmation to be valid in legal proceedings. Samples that test presumptively positive in Screening must undergo secondary confirmation.
If a sample tests presumptively positive during Screening, additional hair is extracted from the initial specimen for Extraction. During this process, drugs are removed from hair at significantly lower concentrations than those present in other testing methods, such as urine or oral fluid, making hair drug screening the most intricate method to execute.
Confirmation of positive screening outcomes is done using GC/MS, GC/MS/MS, or LC/MS/MS. Any positive screening samples undergo necessary washing before confirmation. The entire laboratory process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair guidelines and accreditation to ISO / IEC 17025 standards.

Limitations:
Note: Although commonly dubbed "hair follicle tests", the actual test examines the hair strand, not the scalp’s hair follicle.
When comparing hair follicle testing to traditional urine analysis in Chester, TX, the advantages are clear. Hair tests surpass urine tests in detection accuracy and reliability.

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.
