5 Panel vs 10 Panel Hair Follicle Test: What Each Screens For and What It Means for You

Updated 16 Oct 2026 · By the DrugTestAnswers editorial team

If you've been told you're getting a "5-panel hair test" or a "10-panel hair test," the number is just how many drug classes the lab screens for. Both look back roughly the same amount of time, about 90 days with a standard head-hair sample, and both are handled the same way at collection. The real difference is the list of substances. Below is what each panel usually includes, where labs differ, what a bigger panel means for prescriptions, and how to find out where you stand before the employer does. We may earn a commission from links on this page.

The short version

Neither one is "stricter" in the sense of a longer window. A 10-panel just checks more boxes.

What a 5-panel hair test usually covers

The classic five-panel comes from the five drug classes that federal workplace testing programs were originally built around, and private labs adopted it as their standard:

1. Marijuana (the THC metabolite THC-COOH)
2. Cocaine (cocaine and its metabolite benzoylecgonine)
3. Amphetamines (amphetamine and methamphetamine, often with MDMA and MDA)
4. Opiates (codeine, morphine and 6-acetylmorphine, the heroin marker)
5. Phencyclidine (PCP)

Some labs sell an "extended" 5-panel that widens the opiate group to include semi-synthetic opioids like oxycodone, hydrocodone and hydromorphone. Ask which version you're getting if prescription painkillers are part of your life.

What a 10-panel hair test usually adds

A 10-panel takes the five above and adds five more classes. The exact five vary by lab and by the employer's contract, but a common lineup looks like this:

• Benzodiazepines (such as alprazolam, diazepam, lorazepam)
• Barbiturates (such as butalbital and phenobarbital)
• Methadone
• Oxycodone or other semi-synthetic opioids, on panels that don't already include them
• Propoxyphene on older panels; because it was pulled from the US market in 2010, many labs have swapped it for another class

You'll also see panels that add meperidine, tramadol or fentanyl. Fentanyl in particular isn't on many standard panels unless the employer asks for it, though that's changing. The only way to know your exact panel is to ask the employer, the collection site or the lab listed on your paperwork.

Why the window is the same for both

The look-back period comes from the hair, not the panel. Head hair grows roughly half an inch a month, so a standard 1.5-inch sample cut close to the scalp reflects about the past three months. Drugs reach the hair through the bloodstream while it forms in the follicle, and stay locked in the shaft as it grows out. Whether the lab checks five classes or ten, it's reading the same strand covering the same stretch of time.

Two wrinkles worth knowing:

• Very recent use often doesn't show yet. It takes time for hair containing a drug to grow above the scalp where it can be cut, so use within roughly the last week or so is usually not captured.
• Body hair changes the window. If head hair isn't available, a collector may take chest, armpit, arm or leg hair. Body hair grows more slowly and rests longer, so it can reflect a longer period, often quoted at up to about a year, whatever the panel size.

How sensitive is each class in hair?

Hair testing isn't equally good at everything. That matters more on a 10-panel, since several of the extra classes are harder to catch in hair.

Cutoffs are set by each lab and measured in picograms per milligram of hair. Our cutoff level table explains the units and typical screening levels.

Which one will an employer use?

Employers choose based on cost, industry and what they're trying to catch. A 5-panel is the cheaper, more common default for general pre-employment screening. A 10-panel is more common where the employer specifically cares about prescription drug misuse, for example in healthcare, safety-sensitive private roles or security work. Your offer letter or the collection paperwork often names the test. If it doesn't, it's reasonable to ask HR, "What kind of test is it, and what's on the panel?" People ask that all the time.

If the job is DOT-regulated (trucking, aviation, rail, transit, pipeline, maritime) or federal, the rules are different. Federal programs have their own required drug lists and specimen types, and hair isn't the standard specimen in those programs. Don't use detox products for those tests at all.

Prescriptions on a 10-panel

The extra classes on a 10-panel are mostly medicines people are prescribed: anxiety medication, sleep aids, pain relievers, and methadone for opioid use disorder. A positive for something you take legitimately isn't the end of the story. A medical review officer, a doctor who reviews lab results, contacts you before the result goes to the employer and asks about prescriptions. Have your pharmacy records or prescription bottle ready. Keep in mind that a prescription from someone else, or an old one you've kept using, generally won't count.

What about alcohol?

Neither a standard 5-panel nor a 10-panel hair test screens for alcohol. Alcohol in hair is tested separately, using a marker called ethyl glucuronide (EtG), and only if the employer or program orders it. That kind of test is more common in monitoring programs than in standard hiring.

Cost and turnaround

Hair tests cost more than urine tests because the lab work is more involved, and a 10-panel generally costs more than a 5-panel. The employer usually pays for pre-employment testing. Results commonly take several business days because of the washing, screening and confirmation steps, longer if a positive needs MRO review. Exact prices and timings depend on the lab and the contract, so check with whoever ordered the test rather than trusting a number online.

Is a 10-panel harder to pass?

Only if you've used something on the extra list. If you've only ever used cannabis, a 5-panel and a 10-panel will look at your THC the same way, with the same cutoff and the same window. If you take benzodiazepines, barbiturates, methadone or certain opioids, a 10-panel may pick those up where a 5-panel wouldn't, and then the MRO process comes into play. The panel number doesn't make the test more or less sensitive for any single drug.

Where detox shampoos fit (honestly)

People researching panel sizes are usually also reading about hair detox shampoos. The best-known one is Old Style Aloe Toxin Rid, sold by TestClear. TestClear's directions call for repeated long-contact washes over 3 to 10 days, often followed by Zydot Ultra Clean on test day. Here's the part that matters: there's no independent, peer-reviewed evidence that it, or any shampoo, reliably clears drugs bound inside the hair shaft, and panel size makes no difference to that. Labs wash samples before testing for exactly this reason. If you want to read the product page anyway, it's the Old Style Aloe Toxin Rid listing at TestClear, and our Aloe Toxin Rid review and how-to-use guide covers the directions, schedules and limits in plain terms.

Two safety notes. Routines found online that layer bleach on top of vinegar and detergent have caused chemical burns, so never mix bleach with acids or cleaners. And never use detox products for DOT, FAA, federal, military, court, probation or parole testing.

Check yourself first with a home hair test

A mail-in home hair test sends your sample to a lab and gives you a private result. It's the most useful step for most people reading this, because it answers the question no article can: would you test positive right now? If your result is negative, you can stop worrying about shampoos. If it's positive, you know where you stand and how much time you might need. When you order one, check which drug classes it covers so it lines up with the panel your employer is using.

How to read your paperwork

• "5-panel" or "SAP 5": the five classic classes listed above.
• "5-panel extended" or "with expanded opiates": adds semi-synthetic opioids.
• "10-panel": the five plus five more; ask for the list.
• "Hair, 90-day": standard head-hair window.
• "Body hair" noted: the window may be longer.
• "EtG" or "alcohol, hair": a separate alcohol marker test.

Common questions people mix up

Is a 10-panel twice as long? No, same window. Does a 5-panel skip opioids? No, it includes opiates like codeine, morphine and heroin; it may not include oxycodone unless it's extended. Can a 10-panel detect alcohol? Not unless EtG is added. Will they tell me the result first? If there's a non-negative, the MRO usually contacts you before the employer gets a final result. Can I ask for a different test? You can ask, but the employer sets the policy.

Hair panels vs urine panels with the same name

A "5-panel" or "10-panel" label is used for urine cups and saliva swabs too, so it's easy to mix them up. The drug list can be nearly identical, but the window is completely different. A urine test mostly reflects the last few days for most drugs, longer for heavy cannabis use. A saliva test usually reflects hours to a day or two. A hair test covers months and usually misses the most recent week or so. If you're not sure which specimen you're giving, ask, because it changes everything about what the result will reflect. Our detection times table lays out the typical windows side by side.

What happens at a hair collection

The collector cuts a small bundle of hair, roughly the thickness of a pencil, as close to the scalp as possible, usually from the crown at the back of the head. They often take it from a few spots so there's no obvious bald patch. The root end is marked so the lab knows which end is newest. The sample is sealed in front of you with a custody form, which you sign. It's quick and painless. The same collection is used whether the lab will run five classes or ten; the panel is just what the lab does with it afterwards.

Screening, confirmation and false positives

Every hair sample goes through a screening test first. Anything that screens positive is then confirmed with a more specific method, usually mass spectrometry, which identifies the actual compound. That two-step process is the same on both panels and is a big reason true false positives are uncommon in hair testing. Still, a few things can complicate a result: legitimate prescriptions, which is what the MRO review is for, and environmental exposure questions, which is why labs wash samples and look for specific metabolites rather than just the parent drug. If you believe a result is wrong, you can usually ask the MRO about retesting the original sample.

Does hair color or texture affect either panel?

It affects the drugs, not the panel. Melanin, the pigment in darker hair, tends to bind basic drugs like cocaine and amphetamines more strongly, so dark hair may show higher levels for the same use. That's a known fairness concern in hair testing. Bleaching and other harsh treatments can damage hair and change measured levels by varying amounts, but not reliably, and labs can note treated samples.

If you're worried about the result

If the test is close and you're anxious, it may help to be honest with yourself about timing. The one thing that works every time is time without using: about three months for a standard head-hair sample.
