Typically, you need 1.5 to 2 inches of hair from the crown of your head or your body. Hair tests cater to drugs, alcohol/ETG, or customized testing options.
Over recent years, drug testing methods have increasingly turned to the hair follicle drug test. Employers, courts, and substance abuse specialists are opting for a hair drug test rather than the more common urine test. Hair follicle drug tests are preferred by employers maintaining zero-tolerance policies, judicial systems, and those on probation. The main advantage of a hair follicle test is its extended drug use detection period, typically covering up to 90 days, and collected under observation, making it exceedingly difficult to evade. Nonetheless, the urine test remains the most accurate when detecting recent drug use within the past five days.

Hair analysis is now recognized as an effective means for identifying the usage of alcohol and other substances. Hair offers an extensive timeline of substance intake by capturing biomarkers within the strands of growing hair. When acquired near the scalp, hair can reveal usage within a detection period of up to roughly three months for substances. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches, consisting of about 200 hair strands (comparable to the thickness of a #2 pencil), closest to the scalp will weigh 100mg, which is optimal for analysis and verification. For EtG, additional tests, and/or those exceeding 10 panels, a specimen weighing 150mg is suggested. It's advisable to measure the specimen using a jeweler's scale. If scalp hair is not accessible, a similar amount of body hair can be collected. In the context of head hair, we mean scalp hair solely. Body hair encompasses other hair types (facial, underarm, etc.).
Process Overview
The essential stages in the laboratory handling of a drug testing sample include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary processing of a sample into a lab's records. This involves confirming that the sample is properly sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and filling in any missing data not supplied by an electronic custody chain system.
Screening offers an initial rapid evaluation for substance abuse. While Screening efficiently excludes drug usage for most samples, a screen that is positive requires validation to be court-admissible. Any samples that are initially positive in Screening must undergo additional confirmation.
For samples preliminarily noted as positive during Screening, more hair is extracted from the original sample and prepped for Extraction. During this phase, substances are isolated from hair at concentrations significantly lower than in alternative procedures (such as urine or oral fluid), making hair drug testing the most complex procedure to conduct.
Validation of any positive Screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed before validation as necessary. The complete process from Accessioning to Confirmation undergoes a review under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 specifications.

Note: Although commonly termed "hair follicle tests", the evaluation studies the hair strand and not the follicle beneath the scalp.
