Hair tests detect THC metabolites including delta 8. Learn about detection and testing. Call (877) 731-6362. --- Can delta 8 show up on a hair follicle test? Yes, hair follicle tests can detect delta 8 THC metabolites because they identify THC compounds stored in hair shafts. Hair testing detects drug use over weeks to months, making it effective for monitoring delta 8 consumption. Call (877) 731-6362 for testing information. DETECTION BASICS ## Can delta 8 show up on a hair follicle test? Yes, delta 8 THC can show up on a hair follicle test. Hair follicle tests detect THC metabolites that accumulate in the hair shaft as it grows. Because delta 8 is chemically similar to delta 9 THC, standard hair drug tests designed to detect THC metabolites will also detect delta 8 use. Hair follicle testing is a reliable method to identify drug use over an extended period, typically up to 90 days depending on hair length. This makes it effective for detecting delta 8 consumption within that timeframe. HOW HAIR FOLLICLE TESTING WORKS ## What does a hair follicle test detect and how is it processed? A hair follicle test detects drug metabolites embedded in the hair cortex. When delta 8 THC is consumed, the body metabolizes it and deposits metabolites in the hair as it grows. This allows labs to detect drug use weeks or months after consumption. At AMH Nationwide, hair samples are collected at one of our 20,000+ nationwide collection sites and sent to one of five national lab networks: [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, or ExperTox. Each sample undergoes a sensitive immunoassay screening followed by confirmatory testing using gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-mass spectrometry (LC-MS). All non-negative results are reviewed by a certified Medical Review Officer (MRO) as part of our standard processing to ensure accuracy and proper interpretation. [DETECTION WINDOW](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) ## How long after delta 8 use can it be detected in hair? Delta 8 THC can be detected in hair follicles for up to 90 days or longer, depending on hair length and growth rate. Hair grows approximately 0.5 inches per month, and testing typically analyzes 1.5 inches of hair closest to the scalp to assess recent drug use. Because metabolites accumulate over time, a single use may be detected for weeks, while chronic or frequent use is more readily identified. Hair follicle testing is not effective for detecting very recent use within hours or days. TESTING LIMITATIONS ## Are there factors that affect delta 8 detection in hair tests? Several factors can influence detection including hair color, texture, cosmetic treatments, and frequency of use. Darker hair with higher melanin content may bind more drug metabolites, potentially increasing detection rates. Chemical treatments like bleaching or dyeing can reduce metabolite levels but do not guarantee a negative result. Because hair testing measures drug metabolites embedded within the hair shaft, occasional use might be harder to detect than chronic use. ## Schedule Your Delta 8 Hair Follicle Test Today To arrange a hair follicle test that detects delta 8 THC metabolites, contact AMH Nationwide at (877) 731-6362. Our nationwide network and certified labs ensure reliable results for employers, courts, and individuals. [Call (877) 731-6362](tel:+18777316362)[Contact Us](https://amhnationwide.com/contact-us/) DOT AND NON-DOT TESTING ## Is hair follicle testing used for DOT-regulated delta 8 screening? No, hair follicle testing is not used for DOT-regulated safety-sensitive roles. The Department of Transportation requires federally certified [urine](https://amhnationwide.com/urine-drug-testing/) testing under [49 CFR Part 40](https://www.transportation.gov/odapc/part40) for THC detection, including delta 8. Hair testing is reserved for non-DOT roles or other employer-directed drug testing programs. Employers or courts ordering hair follicle tests can rely on AMH Nationwide’s national lab network for accurate detection and certified Medical Review Officer oversight. ORDERING AND COLLECTION ## How do I get a hair follicle test for delta 8 detection? AMH Nationwide provides the lab order and directs you to one of our 20,000+ collection sites nationwide for hair follicle sampling. We do not offer online ordering; all testing must be arranged by phone or contact. To schedule a hair follicle test or get a quote, call (877) 731-6362. Pricing varies by panel and detection window. After collection, samples are sent to one of five national labs for analysis and reviewed by a certified Medical Review Officer. AMH Reviewed & Maintained By AMH Nationwide Customer Service AMH Nationwide is BBB A+ accredited and routes every order through Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, or ExperTox, all of which use multiple lab certification agencies and standards such as [SAMHSA](https://www.samhsa.gov/workplace/drug-testing)-aligned laboratory protocols, the ANSI National Accreditation Board for forensic testing and calibration, the College of American Pathologists (CAP), and Clinical Laboratory Improvement Amendments (CLIA). Every non-negative screen is reviewed by a certified Medical Review Officer as part of standard processing before a result is released, and chain-of-custody documentation is maintained on every collection.

Hair testing analyzes drug metabolites deposited over time, so occasional use might produce lower levels. Passive exposure is unlikely to cause a positive hair follicle test because metabolites must be incorporated into the hair shaft from the bloodstream, which generally requires actual consumption. Hair treatments such as bleaching or dyeing can reduce the concentration of drug metabolites but do not guarantee a negative result. Labs are trained to account for these factors during analysis. Test results typically return within 3 to 5 business days after the lab receives the sample. All non-negative results are reviewed by a certified Medical Review Officer before release. Hair follicle testing provides a longer detection window (up to 90 days) compared to urine testing (typically 1-30 days), making it more suitable for assessing long-term delta 8 use. Yes, employers may require hair follicle testing for delta 8 THC as part of their drug screening policies, especially for non-DOT regulated positions.
