Average hair follicle test cost

A hair follicle drug test costs between $65 and $200 depending on where you get tested, how many drug panels are included, and whether the test is performed at home or in a lab setting. At-home kits with lab processing fees included typically cost $39 to $150, while in-person lab or hospital tests range from $100 to $200 or more for expanded panels.

Testing method	Average cost
At-home hair follicle test kit (lab fees included)	$39 – $150
Lab or hospital hair drug test (standard 5-panel)	$100 – $125
Lab or hospital hair drug test (expanded panel)	$125 – $200
Employer-ordered hair follicle test	$100 – $200+

Hair follicle testing is more expensive than urine or saliva drug tests, which commonly cost $30 to $60. The higher price reflects the test's broader 90-day detection window and more complex laboratory analysis involving immunoassay screening followed by gas chromatography/mass spectrometry (GC/MS) confirmation.

Cost by test panel

The number of substances a hair follicle test screens for directly affects the price. A standard 5-panel test covers the most commonly abused drugs, while expanded panels can detect up to 18 or more substances, including prescription opioids.

Panel type	Drugs detected	Typical cost
5-panel	Marijuana, cocaine, amphetamines, opiates, PCP	$65 – $125
10-panel	5-panel drugs plus benzodiazepines, barbiturates, methadone, propoxyphene, methaqualone	$100 – $150
12-panel	10-panel drugs plus extended opioids and ecstasy (MDMA)	$100 – $175
18-panel	12 illicit drug metabolites and 6 prescription drug metabolites	$39 – $200

An 18-panel hair test screens for amphetamines, methamphetamines, ecstasy (MDMA, MDEA, MDA), THC, cocaine (including benzoylecgonine, cocaethylene, norcocaine), PCP, heroin (6-MAM), hydrocodone, hydromorphone, codeine, morphine, oxymorphone, and oxycodone. Some at-home kits offering this comprehensive panel are available for as little as $39 when lab fees are bundled in.

Cost by testing location

Where you take the test has a significant impact on the total cost. Labs, hospitals, clinics, and at-home kits all carry different pricing structures, and some options include chain-of-custody documentation that makes results legally admissible.

Testing location	Typical cost	Court admissible?
At-home kit (mail-in to lab)	$39 – $150	Generally no
Walk-in lab (e.g., Labcorp, Quest)	$100 – $200	Yes, with chain of custody
Hospital or medical office	$100 – $200	Yes, with chain of custody
Employer-contracted testing provider	$100 – $200+	Yes

At-home kits are the most affordable option, but results from self-collected samples typically cannot be used in court proceedings or legal matters because the specimen is not collected under supervised conditions. If you need court-admissible results for custody hearings, probation, or legal disputes, you will need to test at a certified lab with proper chain-of-custody documentation.

How a hair follicle drug test works

A hair follicle drug test analyzes a small sample of hair clipped from near the scalp to detect drug metabolites embedded in the hair shaft. Despite its common name, the test examines the hair strand itself, not the follicle beneath the scalp.

Step	Details
Sample collection	100 milligrams of hair (90 to 120 strands) cut at the scalp
Hair length needed	1.5 inches
Initial screening	ELISA immunoassay test
Confirmation test	Gas chromatography/mass spectrometry (GC/MS)
Negative results turnaround	24 to 72 hours
Positive results turnaround	Up to 72 additional hours for confirmation

Collection process

A trained collector cuts between 90 and 120 strands of hair from the crown of your head. The hairs are typically taken from multiple spots to avoid creating a visible bald spot. If you have very little or no head hair, body hair can be used as a substitute.

The collector wraps the sample in foil, places it in a sealed specimen bag, and completes chain-of-custody documentation before shipping it to a certified laboratory. Because the sample is collected in full view of the collector, it is extremely difficult to tamper with or substitute.

Laboratory analysis

Once the lab receives the sample, the hair is first washed to remove any environmental contaminants. The initial screening uses an enzyme-linked immunosorbent assay (ELISA) test. If the sample screens negative, results are typically available within 24 to 72 hours.

If the initial test indicates potential drug use, a second confirmatory test using GC/MS is performed. This confirmation test can identify specific drugs and detect up to 17 different substances. Confirmed positive results are usually available within an additional 72 hours.

Detection window and drugs tested

Hair follicle drug tests provide the longest detection window of any common drug testing method, covering up to 90 days of substance use history. Head hair grows at an average rate of half an inch per month, so a 1.5-inch sample captures approximately three months of drug history.

Drug category	Specific substances detected
Amphetamines	Amphetamine, methamphetamine
Cannabis	THC (marijuana metabolite)
Cocaine	Cocaine, benzoylecgonine, cocaethylene, norcocaine
Ecstasy	MDMA, MDEA, MDA
Opiates	Codeine, morphine, heroin (6-MAM)
Extended opioids	Hydrocodone, hydromorphone, oxycodone, oxymorphone
PCP	Phencyclidine

The test detects patterns of repeated drug use rather than one-time or very recent exposure. Because hair growth rates vary between individuals, the test cannot pinpoint the exact date drugs were used within the 90-day window.

Hair follicle test vs. urine and blood tests

Each drug testing method serves different purposes, and the best choice depends on whether you need to detect recent use or long-term patterns. Hair follicle tests are considered the gold standard for identifying historical drug use over an extended period.

Feature	Hair follicle test	Urine test	Blood test
Detection window	Up to 90 days	1 to 7 days (longer for chronic users)	A few hours to a few days
Typical cost	$65 – $200	$30 – $60	$50 – $150
Collection method	Non-invasive (hair clipping)	Non-invasive (urine sample)	Invasive (blood draw)
Tamper resistance	High	Low	High
Substance detection scope	Comprehensive	Moderate	Current substance levels
Best used for	Long-term use patterns	Recent drug use	Current impairment

Hair follicle tests are the most difficult to cheat. The sample is collected directly from the individual in plain view, making substitution virtually impossible. Despite claims found online, no special shampoos or detox products can remove drug metabolites from the hair shaft. Washing, dyeing, or styling your hair does not affect test accuracy.

Urine tests are more affordable and better at detecting very recent drug use within the last few days. However, they are more susceptible to tampering and substitution. Blood tests provide the most accurate snapshot of current impairment but have the shortest detection window.

Test accuracy

Hair follicle drug tests are highly accurate due to a rigorous two-step testing process. The initial ELISA screening catches potential positives, and the GC/MS confirmation test eliminates false positives caused by dietary items like poppy seeds or hemp seeds.

Accuracy factor	Details
Initial screening method	ELISA immunoassay
Confirmation method	GC/MS (widely accepted standard)
Environmental contamination	Hair is washed before testing to remove external contaminants
Effect of hair treatments	Washing, dyeing, and styling products do not affect results
False positive protection	Two-step process guards against false positives

Research suggests that while hair testing provides results covering a longer period, urine testing may be slightly more accurate for detecting very recent drug use. If you believe your test results are inaccurate, you can typically request an immediate retest.

Prescription medications used as directed will show up on a hair test. If you have a valid prescription for opioids or other controlled substances, your employer or test administrator will likely ask you to provide prescription documentation to explain the result.

Factors that affect hair follicle test cost

Several variables influence how much you will pay for a hair follicle drug test, from the number of panels to the testing provider and turnaround time you need.

Cost factor	Impact on price
Number of panels	More panels = higher cost
Testing location	At-home kits cost less than lab visits
Chain-of-custody documentation	Adds cost for supervised, legally admissible collection
Turnaround time	Rush or expedited results may cost extra
Lab accreditation level	SAMHSA, CLIA, CAP, and ISO certified labs may charge more
Geographic location	Prices vary by region and local market rates
Bulk or employer contracts	Volume discounts available for employer programs

Number of panels: A basic 5-panel test is the least expensive option. Expanding to 10, 12, or 18 panels increases the cost because each additional substance requires separate analysis.

Testing location: Walk-in labs like Labcorp and Quest Diagnostics charge more than at-home kits but provide supervised collection and legally admissible results. Hospital-based testing is typically at the higher end of the price range.

Lab accreditation: Tests processed by labs certified by SAMHSA, CLIA, CAP, and ISO are considered the most reliable. These accredited labs process millions of tests annually and follow strict quality standards, which may be reflected in the price.

Employer contracts: Businesses that order hair follicle tests in bulk or establish ongoing testing programs often receive volume discounts from testing providers.

Who pays for the test

The answer depends on who requests the test and why. Employers, parents, individuals, and courts all use hair follicle testing for different reasons, and payment responsibilities differ accordingly.

Scenario	Who pays
Current employee (employer-mandated test)	Employer pays for the test and compensates employee time
Pre-employment screening	Employer pays for the test; not required to compensate candidate's time
Court-ordered test	Varies; often the individual being tested
Personal or parental use	Individual purchasing the test

If your workplace requires a hair drug test as a condition of continued employment, your employer is required by law to pay for the test and compensate you for the time spent taking it. For pre-employment screening, the employer pays for the test itself but is not required to compensate you for your time.

Parents monitoring their children, individuals screening themselves before an employer-required test, and people involved in custody proceedings typically pay out of pocket.

Frequently asked questions

Can you cheat a hair follicle drug test?

No. Hair follicle tests are considered the most tamper-resistant drug testing method. The sample is collected in full view of the collector, making substitution virtually impossible. Despite claims found online, no special shampoos or detox products can remove drug metabolites from the hair shaft. The lab also washes the sample before analysis to remove environmental contaminants.

How much does an at-home hair follicle test cost?

At-home hair follicle test kits cost between $39 and $150, with lab processing fees typically included. An 18-panel at-home test from some providers can cost as little as $39 with return shipping and lab fees bundled in. Results are usually available within 3 to 7 business days after the lab receives the sample.

How far back does a hair follicle test go?

A standard hair follicle test detects drug use up to 90 days prior to the test. This is based on an average head hair growth rate of half an inch per month. A 1.5-inch hair sample captures approximately three months of drug history.

How much hair is needed for the test?

A hair follicle drug test requires 100 milligrams of hair, which equals approximately 90 to 120 strands cut 1.5 inches long from the scalp. If head hair is insufficient, body hair can be used as an alternative.

How long does it take to get results?

Negative results are typically available within 24 to 72 hours after the lab receives the sample. If the initial screening indicates drug use, a confirmatory GC/MS test adds approximately 72 additional hours. At-home test results generally take 3 to 7 business days.

Does hair dye or styling products affect results?

No. Washing, dyeing, bleaching, and using styling products do not affect the accuracy of a hair follicle drug test. Drug metabolites are embedded within the hair shaft and cannot be removed by external treatments.

Who uses hair follicle drug tests?

Hair follicle tests are used by employers for pre-employment and random drug screening, government agencies for custody determinations, drug rehabilitation facilities, sports organizations, casinos, and individuals or parents seeking personal drug use information. Industries like transportation, construction, manufacturing, and oil and gas production are among the most common users.

Is a hair test more expensive than a urine test?

Yes. Hair follicle tests cost $65 to $200, while standard urine drug tests typically cost $30 to $60. The higher cost of hair testing reflects its longer detection window, more complex laboratory analysis, and greater resistance to tampering.
