You’ve had this job for quite some time – and you’ve done well.

Then your boss springs a hair follicle drug test on you.

And now you’re thinking to yourself, “I’m probably screwed.”

The good news?

You’re probably not – to be honest.

Just because a hair test is hard to cheat and detects drugs you might have used tens of days back (90, to be precise) doesn’t mean you can’t beat it.

In this article, we’re going to discuss just that: how to pass a hair follicle drug test and the best detox shampoo to purify your hair. If you're a cannabis fan or you've had some recent drug use in general, this is for you.

Let's get to it!

How to Pass A Hair Follicle Drug Test - 3 DIY Solutions

1. Abstain from drug use for 90 Days


We know: it can be hard to do it, especially if you love to smoke. But if you can abstain from cannabis (and other substances) for 90 days, you might be best placed to pass a hair test.

This period is long enough for your hair to outgrow the standard length required for a hair follicle drug test, disqualifying the affected parts of your hair to serve as a sample.

We’ve explained it in detail in the subsequent sections.

Stick around!

2. Shave from Head to Toe


If you can’t abstain, you might want to shave from head to toe. Of course, there’s no way someone is going to impose a hair test on you if you’re all that “bald.”

And that’s the beauty of the game: most employers are likely to place you on probation as they await your head hair and/or body hair to regrow.

Still, shaving can look a bit suspicious, especially if you can’t convince your boss why you did it.

3. Bleach Your Hair Before Your Hair Follicle Drug Testing


Don’t give us that look!

Bleaching can actually help remove some drug compounds that are ingrained in your hair.

Worried that your “shouting” hair might send a red flag? Dye it back to its original color before hitting the lab door.

They’ll never know! ...but your hair might be a little fried.

2 Shampoos for Passing Hair Follicle Drug Tests

1. Ultra Clean Shampoo - Use 24 Hours Before Hair Follicle Testing

This 3-in-1 deep cleaning formula destroys external barriers, exposing the inner hair. Then, it attacks the impurities therein: medications, chemical buildup, etc.

The included purifier permeates deep into the scalp, dissolving the compounds that are planted in your hair follicles.

And nope, your hair’s not going to tangle thanks to the included conditioner, which helps you manage it.

A plus!

We strongly recommend that you use this product together with Old Style Aloe Toxin Shampoo – our next entry.

2. Old Style Aloe Toxin Rid Shampoo - Use 3-10 Days Before Hair Analysis

This product employs advanced microsphere technology to rid your hair of impurities.

For optimal results, use it every day (in the days preceding your test). Make sure to pair it with Ultra Clean Shampoo on the day of your drug test, too.

Got your test in 24 hours, perhaps?

Don’t worry.

Simply shampoo your hair as many times as possible. Let the thing sit lathered in your hair for up to 15 minutes during each wash. Then, tack on the Ultra Clean Shampoo before heading to the labs.

Next? Keep your fingers crossed!

DIY Drug Testing Kits - Test Yourself Before the Real Thing

It’s prudent to want to test yourself before crossing paths with the technician, right? That’s where a self-test kit may come in handy.

We recommend the Five-Panel Test Kit.

The urine-based product (genuine at-home hair test kits seem to be hardly available) could help gauge if your system is drug-free in general.

It’s not a hair test, but it is a drug test, so it gives you some idea.

This drug testing kit is not only easy to use but also tests five different drugs, including, opiates, marijuana, and cocaine, simultaneously. Plus, it comes with detailed instructions that may be of help for first-time users.

How Much Hair Is Needed for a Hair Follicle Drug Test?

Not much. About 100 to 120 strands should do the trick.

And no, you’re not going to spot a bald look – the hair is harvested in multiple places of your head.

When it comes to body hair, about the size of a large cotton ball would be all they’re going to need.

How Long Does a Hair Follicle Drug Testing Take for Results?

A negative test will take just 24 hours. A positive test, meanwhile, will take more than this – up to 3 days.

It’s just that if you test positive, the results will need to undergo further testing to confirm it.

How Do Drugs Get in Your Hair?


When you ingest drugs, they are metabolized and released into the bloodstream. Here, they travel throughout your system, including the hair follicles, as molecules.

Then they make their way into your hair strands and are ingrained therein.

This might explain why the extreme ends of your hair (if it’s long) could test positive for drugs you consumed years ago.

Can You Fail a Hair Drug Test from Second-Hand Smoke?

Nope, unless you get high from the second-hand smoke, which is unlikely.

In other words, second-hand smoke can’t determine your hair-test results.

The results are dependent on drugs that are getting into your hair via the bloodstream – and not the outside environment.

We can’t stress that enough!

What Drugs Are Tested for in Your Hair Sample?

While many drugs – both illicit and prescribed – can be tested for in your hair, the most common ones are examined with a 5-panel hair drug test.

This is a one-step check that tests for 5 drugs, namely:
  • Marijuana
  • PCP (phencyclidine)
  • Cocaine
  • Amphetamine/Methamphetamine
  • Opioids

Simpler Hair Follicle Tests

The 1-panel test is the simplest of them all.

This could come in handy if your employer wants to test for just a single substance, mostly alcohol.

But it could be anything from weed to cocaine and opioids.

Advanced hair follicle tests

This comprehensive test picks up a wide range of drugs, including prescriptions, painkillers, and street drugs, in your hair follicle.

The tests check 14 different drugs in tandem, so it's much easier to detect drug use in general. This includes:
  • Tramadol
  • Marijuana/cannabis
  • Benzodiazepines
  • Oxycontin
  • Amphetamines
  • Methadone
  • PCP (Angel Dust)
  • Barbiturates
  • Demerol
  • Sufentanil
  • Propoxyphene
  • Fentanyl
  • Cocaine
  • Opiates

Can Hair Follicle Testing Detect Alcohol?

Sure. Alcohol is one of the many drugs hair testing can detect.

The logic is the same.

Can a Hair Test Detect One-Time Use?

Not usually, but there’s a risk.

For instance, if you’ve used a drug within the last three months, you could test positive for it.

Also, some drugs are extremely potent and could be detected if you’re a casual user, even if you just used them just once, in the (90) days preceding your test.

How Far Back Does a Hair Follicle Test Detect Drugs?


Unlike the urine tests, which have a 7-day look-back period, hair drug tests could pick up the drugs you used in the last 90 days (and beyond).

We’ll explain!

Usually, hair grows half an inch per month. In 90 days (three months), it should have grown an inch and a half long. This is the length of hair required for a standard test.

Body hair could have a longer look-back period, though — it stops growing earlier than the hair on your head.

Does Body Hair Contain Drugs Too?

Hair is hair – be it on the head, chest, legs, arms, etc.

Anyways, we’ll answer your question...

Body hair contains drugs.

How Accurate Is Body Hair Drug Testing?

It’s as accurate as the hair on your head.

This might explain why a lab technician may harvest body hair in addition to head hair.

Can Eyebrows Be Drug Tested for Hair?

Yes, eyebrows can be drug tested for hair analysis. The logic behind it is simple - eyebrows are part of body hair.

All human hair can be drug tested.

However, these brow hairs aren’t typically very long, so the lookbook period may be shorter than head hair samples.

What Can Cause a False Positive Hair Follicle Test?

Certain prescription drugs can cause a false positive reading.

This is why it’s prudent you explain to your employer if you’ve used any prescription drugs in the (three) months preceding your test.

Bottom Line - Passing a Hair Follicle Drug Test Is Not Easy

Though it’s not easy, the products and solutions on this list could help you test negative for substance abuse.

We recommend you use Ultra Clean Shampoo and Old Style Aloe Toxin Rid Shampoo together. These two work as a team, each one doing its role to rid your hair of existing drug compounds.

You could also try an at-home drug test to get an idea of where you’re at.

Don’t get laid off from work just because you failed a hair follicle drug test. Use these products and/or solutions and you could pass a hair follicle drug test – and keep your job.

Good luck!
