What is a Hair Test?
The Sample
We take a small sample (about 1.5 inches) from the head or body.
The Detection
We analyze the hair shaft for metabolites trapped during growth.
The Window
With a long dection window, we scan for drug use from 5 to 90 days ago.
Why Choose Hair Testing?
90-Day Detection Window
While a urine drug test only looks back 2-7 days, hair testing provides a comprehensive 90-day drug history, making it the gold standard for identifying long-term patterns.
Tamper-Proof & Cheat-Resistant
Unlike other methods, it is virtually impossible to use synthetic samples or "cleansing" products to cheat a hair follicle test, ensuring the highest level of integrity for court or workplace results.
Non-Invasive Collection
No more messy cups. Sample collection is quick, professional, and can be done in a standard office setting without the privacy concerns of supervised urine collection.
Court-Admissible Accuracy
Our hair tests are processed in certified laboratories and reviewed by an MRO, making them fully admissible for legal, custody, and DOT-related cases.
Important Considerations
Not for Recent Use
Hair testing is not ideal for "accident" or "reasonable suspicion" testing because it takes roughly 5-10 days for drugs to grow into the hair shaft above the scalp.
Higher Initial Cost
Due to the advanced laboratory analysis required, the price point is higher than a standard 5-panel urine screen, though it offers significantly more data.
Minimum Hair Length Required
The donor must have at least 1.5 inches of head or body hair. If a donor is completely hairless, an alternative testing method (like fingernail testing) must be used.
Sophisticated Lab Cleaning
Our certified lab process includes an extensive decontamination wash on every sample. This ensures the results identify only internalized metabolites, effectively distinguishing between environmental contact and actual ingestion.
Frequently Asked Questions
How far back does a hair drug test go?
A standard hair follicle test provides a 90-day drug use history. We test the 1.5 inches of hair closest to the scalp; since hair grows at about 0.5 inches per month, this represents a 3-month retrospective window.
Can you pass a hair test if you are bald?
Yes. If head hair is unavailable, we can use body hair (chest, leg, or underarm). If a donor has no body hair at all, we offer fingernail drug testing as an alternative, which provides an even longer detection window of up to 6 months.
Do hair detox shampoos or bleach work?
No. Drug metabolites are trapped inside the hair shaft, not just on the surface. Shampoos and bleaches may damage the hair, but they do not remove the metabolites. Our certified lab analysis can still detect drug use even in treated hair.
What is the difference between a 5-panel and 12-panel hair test?
A 5-panel test is our standard screening, covering the most common illicit substances and stimulants. Our Expanded 12-Panel Specialty Test provides a deeper look, adding various prescription-grade sedatives, advanced pain management medications, and other synthetic substances that standard screenings might miss.
How long does it take to get hair follicle results?
Most results are available within 2 to 5 business days. Negative results are typically faster, while non-negative results require additional GC/MS confirmation testing to ensure 100% accuracy.
