6-Month Hair Drug Test Provides Extended Detection for Accurate Drug Screening
The 6-Month Hair Drug Test detects drug use up to 180 days by analyzing a longer hair sample. This method offers extended detection compared to standard 90-day tests, ideal for employers and legal cases requiring a wider monitoring window. Samples are collected at national labs including Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, and ExperTox. Call (877) 731-6362.
What is a 6-Month Hair Drug Test?
A 6-Month Hair Drug Test is a specialized drug screening that analyzes a longer hair sample to detect drug use over approximately 180 days. Unlike the standard 90-day hair test, this extended period is achieved by collecting a larger hair length, typically up to 1.5 inches or more from the scalp.
This test is designed for situations requiring longer detection windows, such as legal monitoring, employee screening, or insurance assessments. The analysis is performed by certified labs including Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, and ExperTox.
How Long Does a 6-Month Hair Drug Test Detect Drug Use?
The 6-Month Hair Drug Test detects drug metabolites embedded in hair strands for up to 180 days prior to collection. Hair grows approximately half an inch per month, so collecting around 1.5 inches of hair allows testing for drug use over six months.
This extended detection window is twice as long as the standard 90-day hair test, providing a broader historical view of drug consumption. It is useful when monitoring long-term abstinence or past drug exposure beyond typical testing periods.
How is the 6-Month Hair Drug Test Sample Collected?
Sample collection involves cutting a small amount of hair close to the scalp from the crown or back of the head. For the 6-month test, a longer segment of hair is required, typically 1.5 inches or more, depending on hair growth rate and lab requirements.
The collection is done at one of the national lab networks including Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, or ExperTox. AMH Nationwide provides the lab order and directs the requester to the appropriate collection site. There is no online ordering.
What Happens During Laboratory Testing for a 6-Month Hair Drug Test?
Once collected, the hair sample is sent to one of the five national labs for analysis. The labs use advanced techniques to detect drug metabolites within the hair shaft, identifying substances used within the past six months.
Every non-negative result undergoes review by a certified Medical Review Officer (MRO) to confirm findings and provide a professional interpretation. This ensures accuracy and compliance with regulatory standards.

This test is preferred when a wider monitoring window is necessary or when urine or saliva tests are inadequate due to shorter detection periods. It is not used for DOT-regulated safety-sensitive testing, which requires federally certified urine protocols under 49 CFR Part 40.

Common Questions
The 6-month hair drug test can detect common substances including marijuana, cocaine, opiates, amphetamines, methamphetamines, PCP, and benzodiazepines, among others, depending on the chosen testing panel.
Hair treatments like bleaching or dyeing may reduce drug metabolite concentrations but do not necessarily invalidate the test. Labs use methods to detect sample tampering or adulteration.
No. DOT-regulated testing requires federally certified urine testing protocols under 49 CFR Part 40. Hair testing, including the 6-month test, is only for non-DOT safety-sensitive roles.
Results typically take 3 to 5 business days after the lab receives the hair sample, depending on the lab network and panel complexity.
Any non-negative test result is reviewed by a certified Medical Review Officer who contacts the individual for verification before confirming the result.
Yes. Drugs incorporated into hair can reflect even single-use events within the 180-day detection window, though detection depends on drug type and amount used.
