The usage of hair testing is now recognized as an effective means for identifying drug and alcohol consumption. Hair can store a lasting record of alcohol and other drug intake by capturing biomarkers within the strands’ fibers as they grow. When hair is taken from close to the scalp, it can produce a detection timeframe of up to roughly three months for both alcohol and other drugs. Hair is easy to gather, relatively hard to tamper with, and simple to transport.
A 1.5-inch section with approximately 200 strands (similar to the thickness of a #2 pencil) nearest to the scalp supplies 100mg of hair, representing the perfect amount for both screening and confirmation. When conducting EtG, additional panels, and/or tests beyond 10 panels, it’s advised to use 150mg of the sample. Using a jeweler's scale for weighing the specimen is suggested. If scalp hair is inaccessible, an equivalent volume of body hair can be taken. By head hair, we mean only scalp hair, whereas body hair signifies any other hair types (facial, axillary, etc.).
Process Overview
The crucial stages in laboratory handling a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial settling of a sample within a lab’s framework. This entails confirming the sample was properly sealed and dispatched, attributing a random LAN (Laboratory Accessioning Number), and filling out any further data inputs not contained in an electronic chain of custody system.
Screening contains a preliminary rapid examination for substances abusive drugs. Though Screening acts as an economical technique to negate drug usage in the bulk of samples, a positive screen must be authenticated to be valid in court. Any samples flagged as positive during Screening indeed need secondary verification.
If a sample is flagged as positive during Screening, additional hair is extracted from the initial specimen for Extraction. Here, drugs are drawn from hair at quantities far lesser than other processes (like urine or oral fluids), which is why hair drug testing is notably the most intricate method to execute.
Verification of any positive screening outcome is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample undergoes a washing process before confirmation when needed. The full laboratory course from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair standards and the certification to ISO / IEC 17025 criteria.

Limitations:
Note: Although labeled as "hair follicle tests", the examination reviews the hair strand, not the hair follicle beneath the scalp.
