If you're in need of a hair or alcohol test, we specialize in hair testing and offer centers across all cities Nationwide to conduct these tests. Generally, 1.5 to 2 inches of hair from the crown or body is required. Hair tests can be evaluated for drugs, alcohol/ETG, or other personalized testing options.
In recent years, hair follicle drug testing has become a favored method for conducting drug screenings. Many employers, courts, and Substance Abuse professionals opt for a hair drug test over the traditional urine test. Hair follicle tests are preferred for zero-tolerance policies by employers, courts, and for those on probation. The key advantage is its longer detection window, up to 90 days, observed during collection, and being nearly impossible to tamper with. However, urine tests remain more precise for drug use within the past 5 days.

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 regarded as a robust mechanism for identifying the consumption of substances like drugs and alcohol. Hair can offer a long-term record of these substances by embedding biomarkers within the fiber composition of growing hair strands. When sourced near the scalp, hair can deliver a detection span of roughly up to three months for alcohol and various drugs. The collection process for hair is straightforward, relatively resistant to tampering, and facilitates easy transport.
A 1.5-inch portion consisting of about 200 hair strands (equivalent to the size of a #2 pencil), taken closest to the scalp, yields 100mg of hair, which constitutes the ideal quantity for both preliminary screening and subsequent confirmation. For EtG, supplemental tests, and tests beyond 10 panels, a sample size of 150mg is advised. We suggest using a jeweler’s scale for weighing the sample. Should scalp hair be unobtainable, an equivalent quantity of body hair may be procured. When referencing head hair, it precisely denotes scalp hair. Body hair pertains to all other varieties of hair (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test involves four essential phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into a lab's system. This step verifies appropriate sealing and shipping of samples, assigns a random LAN (Laboratory Accessioning Number), and finalizes any extra data entry tasks absent from an electronic chain of custody framework.
Screening comprises an immediate preliminary check for substance misuse. Although cost-effective for ruling out drugs in most samples, a positive screen requires validation for legal acceptability. Presumptive positives from Screening necessitate confirmatory testing.
If a sample shows presumptive positivity in the Screening phase, additional hair is extracted from the initial sample for the Extraction stage. Here, substances are extracted from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug analysis.
Confirmation of any positive screen is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples with presumptive positivity are cleansed as necessary. The collective laboratory journey from Accessioning through to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Though often termed as "hair follicle tests", the assay focuses on hair strands, not on the follicle situated under the scalp.

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.
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.
