Hair analysis is recognized as an effective method for identifying drug and alcohol usage. Hair retains a prolonged record of substances by trapping biomarkers within the fibers of the strand as it grows. Sampling close to the skull allows hair to deliver a detection period of up to around 90 days for alcohol and drugs. Collecting hair is straightforward, hard to tamper with, and convenient to transport.
A sample of 1.5 inches from approximately 200 strands near the scalp (roughly matching the thickness of a #2 pencil) will provide 100mg, which is the optimum sample size for screening and confirmation. For testing specifics like EtG, add-ons, or tests exceeding 10 panels, 150mg of hair is suggested. It is advisable to measure the sample with a jeweler's scale. Should scalp hair be unavailable, the same quantity of body hair can be utilized. References to head hair pertain solely to scalp hair. Body hair encompasses all other hair types (such as facial, axillary, etc.).
Process Overview
The laboratory analysis of a drug test result involves four crucial steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where the sample is introduced into a laboratory’s system. This step involves confirming that the sample was sealed and transported correctly, generating a random Laboratory Accessioning Number (LAN), and finalizing any necessary data entry not supplied by an electronic chain of custody system.
Screening is the initial rapid evaluation for substance abuse. Although it is a cost-effective approach to rule out drug use on most samples, confirmation is needed for any positive screening to hold legal weight. Samples that test presumptively positive in Screening must undergo additional confirmation.
In scenarios where a sample tests presumptively positive during Screening, additional hair is extracted from the primary sample for further preparation during Extraction. In this procedure, drugs are extracted at significantly lower concentrations than in other methods like urine or oral fluid testing, making hair drug screening a challenging process.
Validation of a positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if necessary. The comprehensive laboratory process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although often termed "hair follicle tests," the analysis specifically targets the hair strand, not the follicle beneath the scalp.

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.
