Hair testing is increasingly regarded as an effective method for identifying drug and alcohol consumption. Hair offers a prolonged record of alcohol and drug use by capturing biomarkers within the strands of the hair as it grows. When collected near the scalp, hair can reveal a detection period extending up to roughly 3 months for both alcohol and drugs. Collecting hair is straightforward, relatively hard to tamper with, and easy to transport.
A 1.5-inch segment consisting of approximately 200 hair strands (equivalent to the thickness of a #2 pencil) nearest to the scalp will yield 100mg, which is the perfect amount for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advised. It's best to weigh the sample using a jeweler’s scale. Should scalp hair be unavailable, a similar quantity of body hair can be used. 'Head hair' strictly refers to scalp hair, while 'body hair' encompasses all other hair types (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step of integrating a sample into a laboratory's system. This includes ensuring the sample's seal and shipment were proper, providing a random LAN (Laboratory Accessioning Number), and completing any missing data entry that an electronic chain of custody system does not cover.
Screening involves a rapid preliminary test for drug abuse. Though it is economical and can eliminate drug use in most samples, a positive result in Screening requires confirmation to be valid in legal proceedings. Any samples assumed positive in Screening need further confirmation.
Should a sample show a presumptive positive during Screening, additional hair is extracted from the initial sample for the Extraction process. Here, drugs are retrieved from the hair at a significantly lower concentration than in other methods (e.g., urine or oral fluid), making hair drug testing the most challenging method to perform.
Confirmation of any positive screenings is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples considered presumptively positive undergo washing before confirmation as necessary. The full laboratory process, from Accessioning to Confirmation, is supervised under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Limitations:
Note: Although often called "hair follicle tests", the test actually examines the hair strand rather than the hair follicle beneath the scalp.
