With locations across the nation, our centers specialize in hair analysis, requiring 1.5 to 2 inches of hair from the scalp or body for accurate results. These tests are equipped to detect drugs, alcohol/ETG, or tailored hair test options.
Recently, hair follicle drug tests have become more prevalent in drug screening. Many employers, courts, and substance abuse professionals favor this over traditional urine tests. It suits employers with strict no-drug policies, courts, and probation officers. The main advantage is an extended detection window for drug use, lasting up to 90 days, with observed collection to prevent tampering.

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 has emerged as an efficient method for detecting substance use. Hair retains a long-term record of alcohol and drug intake by capturing biomarkers within the hair's growing fibers. When obtained near the scalp, a hair sample can offer around a three-month detection period for alcohol and drugs. It is straightforward to gather, challenging to tamper with, and convenient to transport.
A 1.5-inch section comprising approximately 200 hair strands (roughly the diameter of a #2 pencil) nearest the scalp will yield 100mg of hair, which is considered the optimal amount for examination. For EtG, extra analyses, or tests exceeding 10 panels, a 150mg sample is suggested. It is advisable to measure the sample on a jeweler’s scale. In the absence of scalp hair, a comparable quantity of body hair can be collected. The term head hair refers exclusively to scalp hair. Body hair encompasses all other types, such as facial and axillary hair.
Process Overview
The primary stages in processing a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial incorporation of a specimen into the lab’s system, ensuring the sample was sealed and shipped correctly, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody system.
Screening involves a preliminary assessment for substances of abuse. Though Screening is an economical means to exclude drug usage in most samples, a positive screening result requires Validation to hold up in legal settings. Samples with a presumptive positive in Screening necessitate additional confirmation.
When a sample yields a presumptive positive during the Screening phase, more hair is extracted from the original sample and readied for Extraction. Here, drugs are extracted from the hair in a much lower concentration than in other methods (e.g., urine or oral fluid), which is why hair drug testing is one of the most complex methodologies to carry out.
Confirmation of any positive screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptive positive are cleaned before confirmation as required. The entire lab protocol from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly described as "hair follicle tests", the evaluation itself examines the hair strand rather than the follicle beneath the scalp.
Hair follicle testing in Las Posas, CA, outperforms urine tests through its broader detection scope and higher reliability.

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.
