Hair analysis is regarded as an effective method for identifying drug and alcohol intake. By capturing biomarkers within the fibers of the hair as it grows, hair records a prolonged history of alcohol and other substances. When collected near the scalp, it can offer an approximately 3-month detection timeframe for various substances. Hair collection is straightforward, harder to tamper with, and easily transportable.
Gathering a 1.5-inch sample consisting of about 200 hair strands (about the thickness of a #2 pencil) close to the scalp provides 100mg of hair, which is the optimal quantity for examination and verification. For EtG testing, additional panels beyond 10, or for extended tests, 150mg of hair is recommended. We suggest measuring the sample with a jeweler’s scale. If there isn't enough scalp hair, an equivalent amount of body hair can be collected. "Head hair" indicates scalp hair only, whereas "body hair" includes all other types (such as facial and axillary hair).
Process Overview
The laboratory procedure for a drug test result consists of Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the process of integrating a sample into a lab’s workflow, ensuring it was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data input absent from an electronic custody record.
Screening is a preliminary examination to detect drugs. While it is cost-effective in ruling out drug use for most samples, any positive screen must be verified for legal admissibility. Presumptive positive samples in Screening require further Confirmation.
If a sample shows a preliminary positive in Screening, more hair is extracted from the original sample and prepared for Extraction. Drugs are extracted from hair at a lower concentration than in other methods (like urine or oral fluid), making hair drug screening the most challenging technique.
Confirmation for any initial positive screening is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before Confirmation as required. The whole laboratory procedure from Accessioning to Confirmation is vetted under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although often called "hair follicle tests", the analysis occurs on the hair strand and not on the 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.
