When individuals, employers, or legal professionals in Gwinnett County need the most accurate, long-term view of drug use history, hair drug testing is the gold standard.
While urine tests are common for recent use, they often only detect substances used within the past few days. A hair follicle drug test, however, provides a much longer window of detection, making it impossible to hide habitual drug use.
At ARCpoint Labs of Duluth, we are your local, certified experts in drug and alcohol screening. Unlike online booking services that act as middlemen, we are a physical, locally-owned lab right here in Duluth providing secure, court-admissible testing.
This guide explains everything you need to know about getting a hair drug test in Duluth, GA.
What is Hair Follicle Drug Testing?
Despite the common name “hair follicle test,” the procedure actually involves analyzing a small sample of hair cut from the head (or body) near the scalp.
When drugs are ingested, they enter the bloodstream. As hair grows, it is nourished by blood, and trace amounts of drug metabolites become trapped in the core of the hair shaft. Once trapped, these metabolites remain detectable as the hair grows out, creating a durable timeline of drug ingestion.
Because hair grows at a relatively constant rate, it acts like a “tape recorder” of drug use history.
How Far Back Does a Hair Drug Test Go?
This is the most common question we get at our Duluth lab.
The standard window of detection for a hair drug test is approximately 90 days (3 months).
Hair on the head grows at an average rate of about half an inch per month. Therefore, the standard test requires a sample that is 1.5 inches long, taken close to the scalp, to represent the past three months of history.
- Note: Trimming your hair very short right before a test does not necessarily help. Body hair usually grows slower than head hair, meaning a body hair sample of the same length could potentially look back even further than 90 days.
What Drugs Can Be Detected in Hair?
Hair testing is highly versatile. At ARCpoint Labs of Duluth, we offer various panels depending on your needs, from standard employment screens to comprehensive legal testing.
Standard hair tests typically screen for the following major drug classes:
- Amphetamines (including Methamphetamine and Ecstasy/MDMA)
- Cocaine
- Opiates (Codeine, Morphine, Heroin)
- Phencyclidine (PCP)
- Marijuana (THC)
We can also configure expanded panels to include opioids like Oxycodone, Hydrocodone, and Fentanyl, as well as benzodiazepines and other substances.
Why Choose Hair Testing Over Urine Testing in Duluth?
While urine testing is cheaper and good for detecting very recent use (the last 1-5 days), hair testing offers distinct advantages for employers and legal situations in the metro Atlanta area:
- Longer Detection Window: A 90-day history vs. a few days.
- Harder to Cheat: Urine tests can sometimes be adulterated, substituted, or diluted. Because a certified technician at our Duluth lab collects the hair sample directly from your head, the potential for cheating is virtually eliminated.
- Identifies Habitual Use: It easily distinguishes between a one-time use incident years ago versus an ongoing, lifestyle addiction.

The Benefits of Using a Local Lab vs. National Booking Sites
When you search for “hair drug testing near me,” you will often see national websites that allow you to book online but don’t actually have a location in Duluth. They simply send you to a third-party collection site.
ARCpoint Labs of Duluth is different. We are a locally owned and operated business located physically at 3635 Savannah Pl Dr.
When you choose us, you get:
- Certified Collectors: Our staff is trained specifically in hair collections to ensure sample viability.
- Secure Chain of Custody: Crucial for any legal or employment requirement.

Frequently Asked Questions About Hair Testing
Does the test hurt? No. It is a simple, non-invasive snippet of hair.
How much hair is needed? We usually need a sample about the width of a pencil lead and 1.5 inches long. We take small amounts from different spots on the head to avoid creating a visible bald spot.
Can I wash my hair to beat the test? No. External shampoos, bleaches, or dyes might affect the outer layer of the hair, but drug testing analyzes the inner structure of the hair shaft where the drug metabolites are locked tight.
