Recognized as an adept approach for identifying drug and alcohol consumption, hair testing stands out. Hair captures a comprehensive timeline by embedding biomarkers within the strands of growing hair. A sample taken near the scalp can reveal up to an estimated 3-month detection span for substances like alcohol and drugs. The collection of hair is straightforward, hard to tamper with, and simple to dispatch.
A 1.5-inch section consisting of roughly 200 hair strands (around the size of a #2 pencil) closest to the scalp results in approximately 100mg of hair, which is an ideal quantity for analysis and verification. For enhanced tests, such as EtG or assays surpassing 10-panel tests, 150mg of the sample is advised. It's recommended to use a jeweler's scale for weighing. In situations where scalp hair isn't available, an equivalent volume of body hair can be used. When referring to head hair, this pertains specifically to scalp hair. Body hair denotes all other hair categories (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test outcomes comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary phase where a sample is introduced into a laboratory's system. This phase includes validating that the sample was sealed and transported properly, assigning it a random Laboratory Accessioning Number (LAN), and finalizing any additional data entry not supported by an electronic chain of custody.
Screening serves as an initial assessment for substance abuse. It is a cost-efficient method to typically exclude substance usage in most samples, yet a positive result needs confirmation for legal validity. Samples yielding a presumptive positive in Screening necessitate additional verification.
In cases where a sample shows presumptively positive during Screening, further hair is extracted from the original sample for the Extraction phase. Here, the substances are isolated from hair at notably lower concentrations than alternative methods (e.g., urine or oral fluids), underscoring the complexity of hair drug screening.
Confirmation of a positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation as necessary. The comprehensive laboratory procedure from Accessioning to Confirmation is reviewed under the CAP (College of American Pathologists) criteria for Hair and in line with ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although often termed as "hair follicle tests", the examination focuses on analyzing the hair strand itself, excluding 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.
In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
