In recent years, drug testing methods have increasingly included hair follicle testing. Many employers, courts, and substance abuse experts now prefer hair testing over traditional urine tests. Hair tests are favored by companies with strict drug use policies, judicial systems, and for individuals on probation due to their longer detection period, observing up to 90 days of use, and acting as an observed and nearly foolproof method. On the other hand, urine tests remain accurate for identifying drug use within the last five days.

The use of hair testing has become recognized as an effective method for identifying drug and alcohol consumption. As hair grows, it captures biomarkers of alcohol and drugs, providing a comprehensive long-term history. When collected near the scalp, hair can reflect alcohol and drug usage over a period of up to 3 months. It is easy to collect, relatively hard to tamper with, and straightforward to transport.
A sample consisting of about 200 strands of hair, cutting to 1.5 inches from the scalp (roughly the thickness of a #2 pencil), amounts to 100mg, which is considered optimal for preliminary screening and verification. For tests including EtG, additional specifications, or panels exceeding 10, a 150mg sample is preferred. Utilizing a jeweler’s scale for measurement is advisable. If scalp hair is inaccessible, a comparable amount of body hair can be collected. The term head hair specifically refers to scalp hair, while body hair encompasses all other types (e.g., facial, axillary).
Process Overview
The laboratory processing of a drug test result entails four primary stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into a laboratory's system. This process ensures that the sample was correctly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and includes any additional data entry absent from an electronic chain of custody system.
Screening is the initial rapid assessment for drugs of abuse. Although cost-efficient for negating drug usage in most samples, a positive screen must undergo confirmation to stand up in court. Any samples preliminarily positive at this stage need secondary confirmation.
In cases where the Screening stage yields a presumptive positive, additional hair is taken from the original sample and prepared for Extraction. Here, drugs are isolated from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening compared to other methodologies.
Confirmation of any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are cleansed as necessary. The comprehensive laboratory process, spanning from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair directive and accreditation according to ISO / IEC 17025 criteria.

Limitations:
Note: Although frequently termed "hair follicle tests", the test scrutinizes the hair strand rather than the hair follicle beneath the scalp.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.
It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug 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.
