How to Clean Hair Follicles: Understanding Drug Test Implications
How to clean hair follicles is a common question for those facing hair drug tests. Hair follicle testing detects drug use over a 90-day period and cannot be reliably altered by cleaning methods. AMH Nationwide uses certified labs and Medical Review Officers to ensure accurate results. Call (877) 731-6362 for testing guidance.
What is hair follicle drug testing?
Hair follicle drug testing detects drug metabolites embedded in the hair shaft, reflecting drug use over approximately 90 days. It is used by employers, courts, and probation agencies to verify long-term substance use or abstinence. Hair samples are collected at authorized sites and sent to one of five national lab networks: Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, or ExperTox.
Hair follicle testing is non-DOT for safety-sensitive roles, as DOT regulation requires urine tests under the federally certified 49 CFR Part 40 protocol. AMH Nationwide provides the lab order and directs individuals to a collection site; there is no online ordering.
How long do drugs stay in hair follicles?
Drugs incorporate into hair as it grows, allowing detection for up to 90 days or longer depending on hair length. This detection window is much longer than urine or saliva tests. The hair closest to the scalp is tested to represent recent months. Different substances have varying incorporation rates, but the standard testing panel covers common drugs such as marijuana, cocaine, opiates, amphetamines, and PCP.
Because hair testing reflects past drug use over weeks to months, cleaning hair follicles will not remove or erase drug metabolites already present in the hair shaft.
Can cleaning hair follicles affect test results?
Cleaning hair follicles does not reliably affect the outcome of a hair drug test. Drug metabolites are embedded inside the hair shaft, not just on the surface. Most cleaning methods, including shampoos, detox products, or home remedies, cannot remove these metabolites.
Labs use sophisticated washing protocols to remove external contaminants before testing. Additionally, every non-negative result is reviewed by a certified Medical Review Officer to confirm validity. Attempts to alter hair samples can raise suspicion and may lead to test refusal or further investigation.
How does AMH Nationwide handle hair follicle testing?
AMH Nationwide coordinates hair follicle drug testing by providing the lab order and directing individuals to collection sites nationwide. Samples are analyzed by one of five national lab networks: Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, or ExperTox. These labs follow strict chain-of-custody and testing protocols.
Every non-negative screen undergoes review by a certified Medical Review Officer to ensure accuracy and compliance with regulatory standards. AMH does not allow online ordering; all testing must be arranged via phone at (877) 731-6362.

Are there ways to beat a hair follicle drug test?
Scientifically, hair follicle drug tests are designed to detect drug use over extended periods. Because metabolites are inside the hair shaft, no proven method exists to reliably ‘beat’ or alter the test by cleaning the hair.
Employers and legal entities trust hair testing for its resistance to tampering. Attempting to alter samples or substitute hair can result in test invalidation or disciplinary action. The best approach is to understand the test’s purpose and comply with testing requirements.
What should I do if I have a hair follicle drug test scheduled?
If you have a hair follicle drug test scheduled, it is important to avoid any attempts to alter or clean your hair follicles. Maintain your usual hair hygiene without using detox shampoos or home remedies claiming to cleanse drug metabolites.
Contact AMH Nationwide at (877) 731-6362 to arrange your test and receive guidance on the process. Ensure your hair length meets the minimum requirements, typically 1.5 inches from the scalp, for accurate testing.
