Hair follicle drug tests have become a more prevalent drug testing method in recent years. Employers, courts, and Substance Abuse experts increasingly prefer hair drug tests over standard urine tests. Hair tests serve employers adhering to zero-tolerance policies, legal entities, and probationers. A key advantage is the extended drug detection window—up to 90 days—performed under observed conditions and resistant to tampering. Nonetheless, urine tests remain most accurate for detecting recent drug use within five days.

Hair testing has gained recognition as an effective means for detecting drug and alcohol consumption. Hair offers a prolonged history of drugs and alcohol by capturing biomarkers in the strands of the growing hair. Collected near the scalp, hair can offer a detection period of about three months for drugs and alcohol. Hair is easy to collect, relatively hard to tamper with, and simple to transport.
A sample measuring 1.5 inches, consisting of around 200 hair strands (about the size of a #2 pencil) nearest to the scalp will yield 100mg, the optimal amount for both screening and confirmation. For tests such as EtG, add-ons, or panels exceeding 10, a specimen weight of 150mg is advised. We suggest using a jeweler’s scale to weigh the specimen. If scalp hair isn't available, a similar amount of body hair can be used. When mentioning head hair, we refer exclusively to scalp hair. Body hair encompasses all other types, such as facial and axillary.
Process Overview
The four primary stages in laboratory processing of a drug test are Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, the sample is initially entered into the laboratory’s system, ensuring it was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing additional data entry not included by an electronic chain of custody.
Screening provides a preliminary evaluation for drugs of abuse. Though Screening is a budget-friendly method to dismiss drug usage in numerous samples, a positive result calls for confirmation to be legally valid. Any sample with a presumptive positive result in Screening requires further confirmation.
If a sample is typically positive during Screening, further hair from the specimen is used for Extraction. In this phase, drugs are extracted from hair at substantially lower concentrations than other methods like urine or oral fluid, making hair drug testing one of the most challenging methods to execute.
Positive results from Screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All preliminary positive samples are washed as necessary before confirmation. The comprehensive process, from Accessioning to Confirmation, is assessed under both CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 standards accreditation.

Note: Commonly referred to as "hair follicle tests", the analysis is performed on the hair strands, not the follicles 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.
