In recent developments, hair follicle drug testing has gained prominence as a preferred method for identifying substance use. Many employers, judiciary bodies, and addiction specialists now opt for hair tests over standard urine analysis. Hair follicle tests are favored by employers with no-drug policies, legal institutions, and individuals under probation. Significant advantages of these tests include an extensive detection period of up to 90 days, observation during sample collection, and minimal room for deception.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair analysis is now recognized as a potent means to detect drug and alcohol usage. Hair offers a prolonged timeline of substance use by capturing biomarkers within the fibers of the hair's growth. When obtained near the scalp, hair can reveal up to roughly a 3-month detection span for alcohol and various drugs. The collection process for hair is straightforward, not easily tampered with, and simple to transport.
A 1.5-inch hair sample consisting of roughly 200 strands (akin to the thickness of a #2 pencil) closest to the scalp equates to 100mg of hair, the preferred volume for both screening and confirmation. For tests such as EtG, add-ons, or panels exceeding 10, a specimen of 150mg is advised. It is recommended to measure the specimen using a jeweler’s scale. Should scalp hair be unavailable, a comparable amount of body hair can be collected. "Head hair" refers exclusively to scalp hair. "Body hair" encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial handling of a sample within a laboratory’s system. This includes checking that the sample was sealed and shipped accurately, assigning a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry omitted by an electronic chain of custody system.
Screening involves an initial, rapid assessment for drugs of abuse. While Screening is a cost-efficient method to disregard drug usage in most samples, any positive screen must be verified to hold up in court. Samples with presumptive positivity in Screening require a subsequent confirmation.
For samples with presumptive positivity in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. At this stage, drugs are retrieved from hair at significantly lower concentrations than in alternative methods (e.g., urine or oral fluid), which is why hair drug screening is notably challenging to execute.
Confirmation of any positive screening outcome is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as deemed necessary. The entire laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Though often called "hair follicle tests", the analysis actually examines the hair strand, not 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. 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.
