Hair follicle drug tests are incredibly intimidating! Not only are they highly effective, their detection window is unmatched. Thankfully, there are a few reliable ways to pass a hair follicle drug test – but they’re not easy. 

To pass a hair follicle drug test, you’ll need a powerful detox shampoo and preferably a good cleanser. The goal is to remove traces of drugs from inside the hair cuticles. This process may require a little patience, but it’s easy once you know all the information.

Read on to find out everything you need to know how to pass a hair follicle drug test!

How Does a Hair Follicle Drug Test Work?

Hair follicle tests are commonly used to detect:

  • Amphetamines or methamphetamines
  • THC (marijuana)
  • Ecstasy
  • Cocaine
  • Opioids (Codeine, Fentanyl, oxycodone)
  • PCP
  • Most other illegal drugs

Effective hair follicle testing procedures require hair to be collected directly from your head; not a brush or any other source. During the procedure, a lab worker will chop between 100 and 120 hairs from a few places off the back of your head. If you have little to no hair on your head, they’ll take hair from your armpit, chest, legs, or arms. The collection process is quick and painless, since the hair follicle itself isn’t tested, and the hair isn’t plucked directly from the scalp. 

Generally, the amount of hair collected should be the thickness of a shoelace tip or pencil lead. Standard tests require a minimum sample length of 1.5 inches.

Once the technician has collected enough strands, they’ll send it to the lab for hair drug testing. There, they’ll analyze it for illicit substances that are present in your hair follicles.

What’s the Detection Window of a Hair Follicle Drug Test?

Hair follicle drug tests have become more prevalent in the past decade because they can detect marijuana use from the past 90 days. They’re also less expensive than blood tests. To make matters worse, the hair follicle drug test cutoff levels for marijuana is at 0.10 pg/mg, which means that even a minute amount of the substance can cause you to test positive.

Which Companies Use Hair Follicle Drug Tests? 

Due to its longer detection period, many workplaces are beginning to favor hair follicle tests over standard 5 or 10-panel urine tests. Most of these companies are big corporate or government types that cover in the following industries:

  • Food
  • Automobile manufacturing
  • Oil and gas 
  • Financial

A hair follicle test is far more costly than a urine test, ranging over $100 per test. That being said, it’s still a preferred method of testing in stricter workplaces because procedures are relatively non-invasive and extremely difficult to cheat. Labs can also retest a specimen several times to ensure that results are as accurate as possible.

Companies that Hair Test List

More and more companies are incorporating hair follicle drug testing as part of their pre-employment processes. This is to ensure that potential candidates are disciplined and reliable. Among the big-name companies that incorporate a hair follicle test are:

  • McDonald’s: the Big M is known to request a hair test for pre-employment screening on higher-level candidates. This might be anyone applying for a sales or managerial position. 
  • Ford: as part of the auto industry, Ford is one company that is expected to employ a hair test. Dealerships will also require sales personnel to undergo this type of testing. 
  • ExxonMobil: one of the world’s largest multinational oil and gas corporations, ExxonMobil administers a fairly rigorous drug testing process for safety purposes. This usually includes a hair test before employment.
  • Amtrak: as a member of the DOT (Department of Transportation), it’s no question that Amtrak requires all potential employees to be screened for drug use. The long-distance inter-city service will either use urine or hair testing. 
  • Walmart: one of the largest retail corporations in the world, Walmart definitely has a reputation to uphold. Depending on your location, your local Walmart might employ a urine, saliva, or hair test. 
  • Microsoft: this tech giant is known to have a strict drug-testing policy. Methods can range from urine to hair tests. 
  • Proctor & Gamble: a consumer goods corporation with branches all over the world, P&G has a meticulous hiring process that includes a mandatory drug test. This is either by means of a urine or hair test.

  • Greenway Health: this privately-owned healthcare information company does pre-employment screening using a hair follicle test. 
  • Geico: the auto insurance company incorporates hair tests to determine any drug use in the past 3 months. 
  • Google: on top of its 5-panel urine test, the billion-dollar corp will request a hair test for employees if deemed necessary. 
  • Wegmans: with over a hundred branches across America, the supermarket chain ensures its employees are clean with pre-employment hair tests.

Here are some of the biggest commercial businesses within the trucking industry that employ hair follicle tests.

  • General Motors: as part of its hiring process, the vehicle manufacturer requires potential employees to pass a hair test.
  • Shell Oil: though it may depend on your location, the oil and gas company will usually request a hair follicle prior to employment and up to a manager’s discretion. 
  • JB Hunt: a Fortune 500 company, JB Hunt ensures that only the best employees come to work under its name. Its screening process, therefore, includes a hair test. 

What Won’t Work for Passing Hair Drug Tests? 

There are a number of proven ways to pass a hair follicle drug test, but not every method is effective. Before we get into what works, let’s break down all the methods that don’t quite cut it.

Shaving Your Head

When it comes to hair testing, it would seem that the fastest and easiest way to pass one would be to shave your head, right? Not quite – remember that body hair can be tested just as thoroughly as the hair on your head. 

Detox Drinks or Pills

Though detox drinks and THC detox pills may suffice for those aiming to pass a urine test, they’ll do nothing for anyone trying to pass a hair test. Why? The point of detoxing methods is to dilute your bodily fluids in order to mask or hide any unwanted traces of THC, which does nothing for your hair. Because substances are absorbed in the bloodstream and hair follicles contain blood vessels that supplement hair growth cells, there’s no way to dilute traces there. 

Low-Quality Detox Shampoos

It goes without saying that the best method of passing a hair follicle drug test is by investing in a good detox shampoo. However, you’ll find that there is an abundance of low-quality products and dupes on the market, so you’ll want to do a lot of research before purchasing one. 

Some cheaper options don’t quite penetrate the shaft and only wash out toxins outside of the hair follicle. When researching a detoxing shampoo, go through several reviews before making your decision.

To pass a hair follicle drug test, you’ll need a powerful detox shampoo and preferably a good cleanser. The goal is to remove traces of drugs from inside the hair cuticles. This process may require a little patience, but I’ve listed all the steps, plus the products you’ll need to learn how to beat a hair follicle test!

How Does a Hair Follicle Drug Test Work?

During a hair follicle test, a lab worker will chop hair from a few places off the back of your head. If you have no hair on your head, they’ll take hair from your armpit, chest, legs, or arms.

Once they’ve collected enough strands, they’ll send it to the lab for hair drug testing. There, they’ll analyze if illicit substances are present in your hair follicles.

How Long Does a Hair Follicle Drug Test Go Back?

Hair follicle drug tests have become more prevalent in the past decade because they can detect marijuana use from the past 90 days. They’re also less expensive than blood tests. To make matters worse, the hair follicle drug test cutoff levels for marijuana is at 0.10 pg/mg, which means that even a minute amount of the substance can cause you to test positive.

5 Ways to Pass a Hair Follicle Drug Test

Before anything, stop drug use immediately. Even if you use special products to detoxify your hair, none of them will work if you keep smoking.

Additionally, be sure to wash or discard any object that might have had contact with your head. This includes beanies, hats, hairbrushes, pillowcases, and headrests. Don’t reuse shower caps each time you wash your hair, either. These precautionary measures will prevent you from contaminating your hair follicles with toxins after washing.

Now let’s get to the good stuff! Below I’ve listed the 5 best ways to beat a hair test:

Method 1: Use a Detox Shampoo

THC metabolites in hair can’t be removed by regular shampoo alone. It’s stored in the inner layers of the hair, which is surrounded by the cuticle.

aloe toxin rid shampooWhat you need is a powerful detox shampoo that can open up your hair cuticles and remove toxins from the inside. For this, I recommend Old Style Aloe Toxin Rid Shampoo (available at TestClear.com).

This deep cleansing formula has propylene glycol, a type of synthetic alcohol that functions as an antioxidant, emulsion stabilizer, and moisturizer. This chemical opens up hair cuticles and removes drug metabolites, pollutants, chlorine, and hard water minerals.

Apart from removing traces of drugs from your hair, Old Style Aloe Toxin Rid Shampoo (More info on Aloe Toxin Rid Shampoo) contains avocado oil, soybean oil, and aloe vera juice. These ingredients keep your scalp healthy and condition your hair as you wash it.

How to Remove THC From Hair Follicles With a Detox Shampoo

  1. Wash your hair with warm water.
  2. Massage shampoo into the scalp for 15 minutes.
  3. Leave for three minutes.
  4. Rinse with water.
  5. Repeat the process once every 3 to 10 days before the hair drug test. Use multiple times per day if you have less than 10 days. Make sure you’ve used the shampoo at least 15 times before the hair follicle test.

Method 2: The Macujo Method

The Macujo method is probably the most well-known method of eliminating drugs from the hair. It uses Old Style Aloe Toxin Rid Shampoo along with a few other ingredients for fast results and a synergistic effect.

What You’ll Need

For this to work, you’ll need a combination of various cleansers:

  • Heinz Vinegar
  • Salicylic Acid Shampoo
  • Tide Liquid Detergent
  • Old Style Aloe Toxin Rid Shampoo (Old Formula Only)

How to Pass a Hair Drug Screen Test Using The Macujo Method

  1. Put on a pair of gloves and goggles.
  2. Run warm water through your hair and apply the vinegar. Make sure it reaches into the scalp.
  3. Apply salicylic shampoo.
  4. Wear a shower cap and let the acids settle into the hair. Wait 30 minutes for the mixture to set. This may sting a little.
  5. Rinse off your hair then start using Old Style Aloe Toxin Rid shampoo.
  6. Repeat the previous step.
  7. Clean your hair with a few drops of detergent. Your scalp may turn red and sting.
  8. Repeat the process five times for three days at the minimum. If you have more time before your hair follicle drug test, do it once a day for 10 days.

Method 3: The Jerry G Method

Similar to the Macujo method, the Jerry G method uses Old Style Aloe Toxin Rid as a base, and involves dying and re-dying your hair. According to a research report, “After tests were run, it was concluded that bleached samples show a decrease for all cannabinoids content.”

If you choose this method, you better prepare to shave off all your hair afterward. Bleaching is proven to open up the hair cuticle, but it’s also severely damaging. That’s why most people would rather use the Macujo method to pass a hair test.

What You’ll Need

Be sure to ask help from someone who has experience bleaching their hair before you try this process. It’s a strong substance that should be handled with care.

  • Peroxide Bleach
  • Old Style Aloe Toxin Rid Shampoo
  • Ammonia-Based Hair Dye (In Your Natural Hair Color)
  • Baking Soda

Removing Drug Metabolites With the Jerry G Method

  1. Bleach your hair then re-dye it to your natural hair color.
  2. Wash your hair using Old Style Aloe Rid Toxin Shampoo.
  3. Let your hair rest for 10 days then repeat the first two steps. If you don’t have enough time, wait until the day before your hair drug test to repeat steps 1 and 2.
  4. On the day of your hair drug test, make a thick mixture of baking soda and water. Apply it onto your hair, making sure to cover your entire scalp.
  5. Wash your hair with Old Style Aloe Rid Toxin Shampoo again.

Method 4: Get Rid of Drugs Using a Relaxer

If you have some experience using a relaxer, now’s the time to put that to good use. That’s because a relaxer is proven to extract drug metabolites from the hair.

Use both the relaxer and a detox shampoo a few days before your hair follicle test then repeat the process before the drug test itself. Same with the other methods, I recommend using a powerful clarifying shampoo like Old Style Aloe Toxin Rid Shampoo.

Method 5: Detox Your Hair The Naturally

If you’re wondering how to pass a hair drug test naturally, it shouldn’t be impossible with the steps below. This process is usually done to remove hair treatments, relaxers, or chemicals from the head.

What You’ll Need

The ingredients you’ll need to create a hair detox mask are inexpensive and easy to find.

  • Bentonite Clay Powder
  • Apple Cider Vinegar
  • Aloe Vera Gel
  • White Vinegar
  • Old Style Aloe Toxin Rid shampoo

Steps to Eliminate Drugs From Your Head Naturally

  1. Combine half a cup each of all the ingredients.
  2. Apply the mixture on your hair. Be sure that it touches the scalp.
  3. Wear a shower cap and let the mask settle for half an hour.
  4. Rinse the hair with white vinegar.
  5. Use a clarifying shampoo like Old Style Aloe Toxin Rid shampoo to get rid of residual chemicals from the hair.

FAQ

As we mentioned, there are a good number of ways to prepare yourself for a hair follicle test. Some methods may be more effective than others. Here’s a recap of everything you need to know before taking your test. 

Does Hair Detox Shampoo Actually Work?

Yes, but not all of them. You’ll need to source a detox shampoo with a strong formula. For a detox shampoo to be effective, it needs to achieve three key things:

  1. It must open up your hair shafts, which have a hard top layer that require a strong substance to break apart.
  2. It must flush out the toxins.
  3. It must close the shaft up after the toxins are washed out.

Note that different brands of hair follicle detox shampoos will vary in terms of the steps you have to take for them to work best. Some detox shampoos work better when partnered with other products and home remedies. Others will require you to use the product at least 3 – 5 days before your drug test. However, more often than not a good shampoo will do all the work on its own.

How to Choose the Best Hair Detox Method?

All of the methods above work, but it’s best to choose one based on the severity of your drug use. Light and occasional smokers can try less invasive methods, while heavy users should go for more extreme measures.

Additionally, those with coarse or curly hair should go for stronger methods. Thick hair holds more drug compounds, so you’ll need to take a few extra precautions. 

How to Get Drugs Out of Your Hair Fast?

Because hair follicle tests are designed to detect drug use over a longer span of time, the best way to cheat one is to abstain from drug use for as long as possible. Nevertheless, you’ll sometimes have to take a hair test on short notice and using a detox shampoo is your best bet to passing it. 

The Macujo method has proven successful for most people who try it, although you’ll need to use it for at least 5 days depending on how heavy a user you are. 

How to Pass a Hair Follicle Test for CPS?

How to Pass a Hair Follicle Test for CPSIf you are caught using drugs by Child Protective Services (CPS) they can easily deem your household an unsafe environment for children. Though you have the right to refuse a hair drug test, doing so can create suspicion within the CPS. You are legally required to take a hair test if given a court order by the CPS and refusing to do so can result in your child being withheld from you. Preparing for a CPS hair follicle drug test is the same as any other, although you’ll have to tread carefully given the sensitive circumstances. 

Depending on your location, you may be required to take your test at an authorized CPS facility, at which you will be closely observed. Though there is no way to reschedule your test, showing up at the premises with your identification can cause a social worker to send another referral for a test on a different date, which could potentially give you the time you need to get clean.

If you test positive for the use of marijuana and it is legal in your state, it is at a social worker’s discretion to gauge whether the levels you’re consuming pose a danger to your child. However, it is perfectly possible for an investigation to be dropped so long as you can prove that you do not smoke in front of your children and that the marijuana is stored in a secure area. Testing positive usually means you’ll have to undergo a second test, during which CPS will expect your THC levels to drop. Thus, it’s important that you take this time to detox and refrain from smoking any product.

Depending on your level of cooperation, a standard investigation will usually last an average of 30 days, during which you can prepare for your hair test if it was not already administered initially. However, tricky situations have seen investigations that last for months. To prevent the CPS from further pursuing a case against you, you’re usually given the option to undergo a drug treatment program, which you should definitely agree to. Supervision during this time is usually minimal and reassures social workers that you aren’t a danger to your children.

How to Pass a 5-Panel Hair Follicle Drug Test? 

Hair tests generally have a detection period of up to 90 days since your last intake of any substance. However, some traces may remain in the body longer and will depend on what kind of user you are. The more you use, the longer it’ll take to flush out any toxins. As a general rule, you’ll want to abstain from taking any substance as soon as you know you’re scheduled for a drug test. Whether you use a detox shampoo or other remedy is up to you.  

How to Pass a Hair Drug Test With Dreadlocks?

Dreadlocks can be a little tricky to clean, but the Macujo method should do the trick!

The big difference is that you have to wash your dreadlocks as many times per day as you can, and as many days as possible. Stock a lot of products in advance, so you don’t miss a day of washing.

You should also scrub extra deep. Buy a scalp scrubber from your local drugstore, since it can help clear the buildup inside your dreadlocks and cleanse each strand thoroughly. Discard the scrubber after every use to avoid reintroducing toxins.

How to Pass a Hair Follicle Test for Weed? 

Whether an occasional or chronic user, THC can remain in your system anywhere between 3 to 30 days. However, detection windows will rely entirely on what type of test you’re taking. As we mentioned before, weed is traceable in a hair test for up to 90 days. If your hair grows at a quicker rate, regular trims and a detox shampoo can improve your chances of passing a test.

How to Pass a Hair Follicle Drug Test for Methamphetamine? 

Meth can be detected in hair anywhere from 7 to 10 days in urine, but will remain detectable by a hair test for up to three months. Hair tests won’t always pick up on a single use of meth, and are better for testing chronic users. When it comes to meth and detection, your best bet, along with a detox shampoo and home remedies, is to abstain from the substance altogether.

How to Choose the Best Way to Get Rid of THC From the Hair

All of the methods above work, but it’s best to choose one based on the severity of your drug use. Light and occasional smokers can try less invasive methods, while heavy users should go for more extreme measures.

Additionally, those with coarse or curly hair should go for stronger methods. Thick hair holds more drug compounds, so you’ll need to take a few extra precautions.
