Ideally, you should have hair lengths ranging from 1.5 to 2 inches either on your head or body. Hair analyses can detect drugs, alcohol/ETG, or can be customized to suit specific needs.
Recently, the trend in drug testing has increasingly leaned towards hair follicle testing. Numerous employers, judicial systems, and substance abuse experts are opting for hair drug assessments over traditional urine tests. Hair follicle evaluations are favored by employers with strict no-drug policies, legal settings, and individuals under probation. The chief advantage of hair follicle drug tests is their extended detection span, which typically reaches up to 90 days, executed under monitored conditions, rendering them nearly foolproof. Nevertheless, urine tests remain the most reliable for recent drug use within the past 5 days.

Hair analysis is recognized as an effective means for identifying drug and alcohol consumption. By securing biomarkers within the fibers of the growing hair strand, hair offers a prolonged tracking of alcohol and other substances. When taken near the scalp, hair can cover a period of up to roughly 90 days for detecting alcohol and substances. Hair collection is straightforward, fairly resistant to tampering, and convenient for transport.
A 1.5-inch segment comprising roughly 200 hair strands (analogous to the size of a #2 pencil) nearest to the scalp yields 100mg—the perfect quantity for analysis and verification. For testing EtG, additional testing, and/or assessments over 10 panels, a 150mg sample is preferred. It’s advised to measure the sample using a jeweler’s scale. If scalp hair isn't available, a corresponding amount of body hair can be used. When referring to head hair, it specifically means scalp hair. Body hair encompasses other types like facial and underarm hair.
Process Overview
The primary procedures in the lab processing of drug tests encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial entry of a sample into a laboratory’s framework. This process confirms that the sample was properly sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and completes any missing data entry not handled by a digital chain of custody system.
Screening involves a preliminary rapid assessment for the presence of drugs. Although Screening offers a cost-efficient approach to dismiss drug use for most samples, a positive screen necessitates confirmation to be legitimate in legal scenarios. Any samples indicating a potential positive during Screening need a confirmatory test.
For samples preliminarily positive at the Screening phase, more hair is obtained from the initial sample for Extraction. Here, substances are retrieved from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), which is why hair drug tests are among the most challenging to execute.
Verification of any positive Screening outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo washing before confirmation if necessary. The complete lab process, from Accessioning through Confirmation, is audited under the CAP (College of American Pathologists) Hair designation and aligns with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly termed as "hair follicle tests", the test itself examines the hair strand and not the follicle beneath the scalp.

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.
