In our comprehensive review, we delved into thousands of Reddit messages and consulted with drug testing specialists to uncover the various methods people employ to pass hair drug tests.

Our goal is to provide you with a thorough understanding of all these methods.

We’re here to guide you through which methods are effective and which aren’t, including those that have scientific backing.

For each method, we’ll include information on how much it costs and how much time it will take.

It’s crucial to note that many individuals resort to techniques that can cause serious damage to both hair and scalp.

However, rest assured, we’ll also introduce you to methods that are safe for your hair.

Hair drug test essentials

First off, let’s break down the basics of what a hair drug test involves, because understanding this is key to figuring out how to pass one.

During the test, the collector snips about 1.5 inches of your hair. This sample doesn’t just get bagged and tagged; it’s actually dissolved in a special liquid.

After that, they measure how much of certain drug metabolites are hanging out in the liquid. If there’s too much of the drug residue, above a certain limit, that’s a red flag, and you won’t pass the test.

So, the goal here is clear: you’ve got to get those drug metabolites out of your hair before the test.

How to remove drug metabolites from the hair

Now, let’s talk hair structure. Your hair isn’t just, well, hair. It’s made up of three main parts: the cuticle (the outer part), the cortex (the middle zone), and the medulla (the innermost section).

Here’s the deal: those drug metabolites we talked about? They set up camp in the cortex. So, to pass the hair drug test, you’ve got to evict them from there.

hair structure

Here’s a simplified game plan: you start by opening up the cuticle. This gives you access to the cortex, where you’ll need to dissolve those drug metabolites.

Once they’re dissolved, you’ve got to wash them out. But we’re not done yet! The final step is sealing that cuticle back up to keep your hair healthy and strong.

Next up, we’re going to share the various strategies people try for this process, and more importantly, we’ll reveal the ones that truly get the job done. Stay tuned!

Strategies for passing a hair drug test

When it comes to passing a hair drug test, individuals often turn to two main approaches: home remedies and detox shampoos.

Home remedies

Home remedies typically involve the use of common household substances such as bleach or vinegar.

While these methods are often cost-effective, they come with significant drawbacks. The harsh nature of the chemicals used can severely damage both the hair and scalp, necessitating cautious application.

These methods can also be quite painful and time-consuming, requiring an array of ingredients and lengthy preparation.

Furthermore, there’s a risk that the visible damage to your hair and scalp might prompt the test collector to take a sample from another body part.

Surprisingly, when considering the quantity of ingredients needed, these remedies might not always be less expensive than purchasing a high-quality drug test detox shampoo.

Detox shampoos

In contrast, drug test detox shampoos present a less damaging solution, with some brands even boasting scientifically proven effectiveness.

However, they tend to be more expensive than DIY methods, and unfortunately, not all shampoos marketed as “detox” are effective for passing drug tests.

The list of home remedies for passing a hair drug test

The Macujo method

You’ll need

  • Rubber gloves: $4
  • Goggles: $10
  • Old Style Aloe Toxin Rid Shampoo: $200
  • Clean and Clear Deep Cleaning Astringent containing salicylic acid: $5
  • White vinegar: $3
  • Tide liquid laundry detergent: $10
  • A shower cap or plastic bag: $2

Total cost: $234

Here’s the procedure

  1. First, protect yourself with gloves and goggles. Wet your hair, then massage in the vinegar, followed by the astringent, without rinsing between applications.
  2. Cover your hair and let it soak for 30-45 minutes.
  3. Afterward, rinse your hair and wash it with Aloe Toxin Rid Shampoo.
  4. The next step involves Tide detergent, which can be quite harsh, so proceed with extreme caution.
  5. Some individuals opt to repeat this process several times before their test.

Time required

Single cycle: Approximately 1 to 1.5 hours. This includes the application of products, the 30 to 45-minute waiting period, and thorough rinsing.

Daily time: If the maximum recommended usage is to repeat the process twice a day (which is a common recommendation to ensure thorough cleansing), you’re looking at about 2 to 3 hours per day dedicated to this method.

Total time: If you’re preparing for a hair follicle test and start the method 5 days before your test, at the maximum recommended usage, you would spend a total of 10 to 15 hours on this process over the course of those 5 days.

A word of caution

The Macujo method can be highly detrimental to your hair and scalp’s health. The chemicals involved are potent and can cause irritation, burns, or lasting damage.

It’s important to note that products like Zydot Ultra Clean and Toxin Rid Old Style Aloe Shampoo can be effective on their own.

The extensive list of ingredients in the Macujo method might be unnecessary and overly harsh, particularly the use of laundry detergent.

Be prepared for potential hair and scalp damage, and remember that test collectors can opt for samples from other body areas if they notice the damage.

The Jerry G method

You’ll need

  • Rubber gloves: $4
  • Goggles: $10
  • Permanent hair dye with ammonia: $8
  • Baking soda: $1
  • Toxin Rid Old Style Aloe Shampoo: $200
  • Shower cap or plastic bag: $2

Total cost: $225

Here’s how to proceed

  1. First, ensure you’re wearing your protective gloves and goggles because the chemicals involved are quite potent and can cause skin and eye irritation.
  2. Begin by applying a permanent hair dye containing ammonia, following the instructions on the kit to cover all your hair.
  3. Ammonia is known for its potential to break down the hair cuticle, which might help in eliminating drug metabolites.
  4. After dyeing, it’s crucial to wash your hair thoroughly using Toxin Rid Old Style Aloe Shampoo or a similar detox shampoo.
  5. Ensure you rinse out all traces of hair dye. Then, allow your hair to air dry completely; avoid using a blow dryer as the chemicals and dye have already made your hair vulnerable to damage.
  6. It’s advisable to wait for at least 10 days before repeating the process to give your hair and scalp time to recover from the chemical exposure.
  7. After this period, you’ll need to repeat the dyeing and washing process, followed by applying a paste made of baking soda and water the day before your test.
  8. This paste is thought to further open the hair cuticles, potentially aiding in the removal of any remaining drug metabolites.
  9. Finish by rinsing out the baking soda paste and washing your hair once more with the detox shampoo.

Time required

Single cycle: Approximately 2 to 3 hours. This includes the time for the hair dye application, washing, and baking soda treatment, but not the 10-day waiting period.

Daily time: This method is not performed daily. It requires a 10-day waiting period between the two dyeing sessions. Each dyeing and washing session may take around 2 to 3 hours, and the baking soda application on the last day may take an additional hour or so.

Total time: Approximately 4 to 6 hours of active treatment (split between two sessions of dyeing and washing, and one session of baking soda application), spread out over an 11-day period. This does not include the waiting time of 10 days between treatments, during which no active treatment is performed.

A word of caution

The Jerry G method is notably harsh and can cause substantial damage to both your hair and scalp.

The chemicals used can lead to hair breakage, scalp irritation, burns, and long-term damage. Furthermore, there’s no scientific consensus that this method is effective for passing a hair follicle drug test.

Be aware that the use of ammonia-based dye and other chemicals can be detrimental to your hair’s health. If the damage is noticeable, the test collector may opt to take the hair sample from another part of your body.

The Reverse Macujo method

  1. Start by donning your gloves and goggles for protection.
  2. First, wet your hair with warm water and carefully work a generous amount of Tide detergent into your hair, leaving it in for about an hour.
  3. Please note, Tide is not designed for skin or hair, so proceed with caution.
  4. Next, rinse out the Tide completely and apply the Clean and Clear Astringent.
  5. Cover your hair and let it soak for 30 minutes.
  6. Afterward, rinse out the astringent and soak your hair in your choice of vinegar for another 30 minutes.
  7. Finally, wash and condition your hair to counteract the drying effects of the treatment, leaving the conditioner on for about 10 minutes.
  8. After these steps, do a final rinse, and gently towel-dry your hair. Avoid using a hairdryer as your hair may be fragile after this treatment.

Method from Acrobatic_Shelter765

Found on a Reddit thread, this method shared by Acrobatic_Shelter765 involves a meticulous washing routine designed to help individuals pass hair drug tests.

It’s quite intensive, so let’s break down what you’ll need and how to proceed.

Source: https://www.reddit.com/r/drugtesthelp/comments/tfau3v/comment/imf1dgq/?utm_source=share&utm_medium=web2x&context=3

What you’ll need

    • Regular shampoo: $7
    • Baking soda: $1
    • Clean & Clear deep cleaning astringent: $5
    • Liquid Tide detergent: $12
    • Apple cider vinegar: $4
    • Shower caps: $3

Total cost: $32

Step-by-step instructions

  1. Begin by shampooing your hair for about 5 minutes, making sure to rinse it thoroughly.
  2. Next, scrub your hair vigorously with baking soda for roughly 6 minutes. Let it sit for an extra 4 minutes, then rinse thoroughly and dry your hair.
  3. You’ll want to repeat the initial step — shampoo and rinse once more.
  4. Now, apply the Clean & Clear deep cleaning astringent to your hair, scrubbing for about 6 minutes. Put on a shower cap and allow the astringent to sit for 30 minutes.
  5. Mix a small amount of liquid Tide detergent with the astringent and scrub your hair for another 6 minutes. Rinse well.
  6. It’s time to repeat the first step again — shampoo and give your hair a good rinse.
  7. Spray your hair with apple cider vinegar, continuing to scrub for 6 minutes.
  8. Apply more Clean & Clear astringent, blending it with the vinegar in your hair. Cover your hair with a new shower cap and wait another 30 minutes.
  9. Use a bit of liquid detergent to scrub your hair vigorously for approximately 6 minutes, then rinse thoroughly.
  10. Conclude with the first step — one final shampoo and rinse.

Time required

Single cycle: Approximately 1 hour and 40 minutes. This includes the time for shampooing, scrubbing with various substances, letting them sit, and rinsing.

Daily time: Each cycle takes about 1 hour and 40 minutes, and if you’re doing the maximum recommended 20 washes spread over a few days, you might do up to 3 cycles a day, which would total approximately 5 hours per day.

Total time:** If you’re doing 20 cycles in total, and you manage to do 3 cycles a day, it would take you around 6-7 days to complete, with a total time investment of approximately 33 hours and 20 minutes.

Additional comments

This process is methodical for a reason. Ingredients like baking soda and Tide detergent are bases used to pry open the hair cuticle, which is why it’s vital to shampoo after using them. On the other hand, the Clean & Clear astringent and vinegar, which are acids, serve to close the cuticle.

To enhance this method’s effectiveness, some lifestyle adjustments are necessary. Consider shaving body hair to avoid samples being taken from other areas. Also, it’s advisable to use a fresh pillowcase nightly and not to reuse towels.

For added confidence, you might want to use a hair testing kit from a local store to check how effective the washes are. While you wait for the results, continue with the washing routine.

It’s wise to get a haircut before the actual test to eliminate the ends of the hair, which hold the longest history of drug use.

On your test day, treat your hair with the Zydot mixture as a final step.

Remember, this method is rigorous, involving a total of 20 washes for maximum effectiveness. Be prepared for a committed process.

Saucymesser’s method from Reddit

In a detailed Reddit post, a user named saucymesser shared a unique hair cleansing method aimed at preparing for a hair drug test. Here’s a breakdown of what you’ll need and the steps involved, all presented in a way that’s easy to understand and follow.

What you’ll need:

  • Shower cap: $2
  • White Distilled Vinegar (64oz): $4
  • Clean and Clear Astringent (Step 2/pink one): $5
  • Baking soda (used here as a substitute for the more expensive aloe rid nexxus old formula): $1
  • Tide Liquid Laundry Detergent (small size): $5

Total: $17

Step-by-step instructions:

  1. First, as a precaution, shave all the hair from your legs, chest, armpits, and groin area. This ensures that you’ll need to apply the cleansing method only to your scalp, simplifying the process.
  2. Start by wetting your hair thoroughly with warm water. You can do this over a sink in either your kitchen or bathroom.
  3. Next, pour 1-2 cups of White Distilled Vinegar onto your scalp, making sure to massage it in for several minutes.
  4. Without rinsing off the vinegar, proceed to apply 1-2 ounces of Clean and Clear Astringent to your scalp. Continue massaging, letting the astringent blend with the vinegar for a few more minutes.
  5. Then, cover your hair with a shower cap, allowing the vinegar and Clean and Clear mixture to sit and work their magic for about an hour.
  6. After the hour is up, hop in the shower and wash the mixture out of your hair using baking soda. You can mix it with a small amount of shampoo if you prefer. Make sure to work it well into your hair, let it stand for a bit, and then rinse thoroughly.
  7. While you’re still in the shower, apply a small dollop of Tide Liquid Laundry Detergent to your hair. It’s important to massage this in thoroughly before completely rinsing it out.
  8. After the laundry detergent is all rinsed out, it’s time to apply baking soda to your hair again. This step is crucial as it helps heal your scalp, keeps your hair soft, and provides further cleansing.

Time required

Single cycle: Approximately 1.5 hours. This includes the initial shaving (variable, approximately 30 minutes, depending on individual speed and hair density), wetting the hair and applying vinegar (several minutes), adding and massaging with Clean and Clear Astringent (several minutes), waiting with the shower cap on (1 hour), and the subsequent steps of washing with baking soda, Tide, and again with baking soda (each requiring several minutes).

Daily time: If the maximum recommended usage is to repeat the process up to three times in one day, you’re looking at about 4.5 hours per day dedicated to this method (1.5 hours for each cycle).

Total time: If you’re preparing for a hair follicle test and start the method 3 days before your test, at the maximum recommended usage, you would spend a total of approximately 13.5 hours on this process over the course of those 3 days.

Additional comments:

This method is essentially a variation of the well-known Macujo method. It’s designed to cleanse your hair and hair cuticles of any signs of drug use, mimicking lab cleansing processes but without the follow-up testing.

If you have the time and supplies, it’s advisable to repeat this entire process up to three times, just as the original poster did.

Please be very careful during this process to avoid getting any of these substances in your eyes, ears, or mouth. If an accident happens, seeking medical help immediately is imperative.

This method might not be the best choice for those with particularly sensitive scalps, as it can cause irritation.

The recommendation to shave hair from other parts of the body is a precaution, in case the testers decide not to take hair from your scalp.

Using baking soda is a cost-effective alternative to the original aloe rid nexxus formula, fulfilling a similar role in the cleansing process.

  • Scrub your hair vigorously with this concoction and leave it in for 30 minutes before rinsing thoroughly with water.
  • Generously apply Tide laundry detergent to your hair, scrubbing thoroughly.
  • Leave this on for 15 minutes before a complete rinse.
  • Get animal-grade propylene glycol from a supplier like Tractor Supply Co. Apply it to dry hair and let it sit for 15 minutes. You’ll need to repeat this application twice, ensuring you wash your hair in between each application.
  • The night before your test, give your hair a good scrub with Zydot. Those with longer hair may need two boxes.
  • On the test day, do another Zydot treatment and then head straight to your testing location.

Avoiding recontamination

It’s essential to clean all combs, brushes, and hair accessories with alcohol, removing any old hair.

You might also consider buying new ones. Use a different clean towel after each treatment to avoid recontamination, and wash your pillowcases in hot water to get rid of any residues.

Focus on the back near the crown and the sides of your head during treatments, as these are common sample collection areas. Use your fingertips for scrubbing to avoid irritating or breaking the skin on your scalp.

Time required

Single cycle: Approximately 3.5 hours. This includes the baking soda treatment (1 hour), the vinegar and salicylic acid treatment (30 minutes), the Tide hair scrub (15 minutes), the propylene glycol treatment (45 minutes for two applications with washes), and the Zydot treatment (1 hour for two treatments).

Daily time: If the maximum recommended usage is to repeat the process once a day (considering the intensity of the treatments), you’re looking at about 3.5 hours per day dedicated to this method.

Total time: If you’re preparing for a hair follicle test and start the method 3 days before your test, at the maximum recommended usage, you would spend a total of approximately 10.5 hours on this process over the course of those 3 days.

  • If you wish, you can apply a no-lye hair relaxer according to the product’s instructions to potentially further open hair cuticles.

Before the test

Use Zydot or a similar hair detox product as instructed, but add propylene glycol during the second step of the process. On the test day, prepare a baking soda paste and apply it to your hair for 30 minutes. Use a cleansing shampoo like High Voltage, following the instructions and adding propylene glycol during the second step.

Head to the testing facility about 30 minutes after completing the cleansing shampoo process.

Additional comments

This method is quite intensive and involves various chemicals that could potentially harm your hair and scalp.

Ensure your skin is protected throughout the process to avoid chemical burns. The effectiveness of these methods is not guaranteed, and results can vary.

They’re not scientifically proven, and there’s a risk they might not work.

Given the potential risks and the lack of guaranteed success, proceed with caution and consider seeking professional advice before starting. Always prioritize your health and safety.

Time required

Single cycle: Approximately 4 to 5 hours. This includes the time for the Altered Macujo Method, Reverse Macujo Method, and the optional steps, but not the final preparations on the test day.

Daily time: This method is not recommended to be performed daily due to its intensity and the harshness of the chemicals used. If repeated, significant recovery time should be allowed between sessions to prevent damage to the hair and scalp.

Total time: Approximately 4 to 5 hours for one complete cycle, excluding the test day. If you opt to repeat the process or include additional steps, the total time will increase accordingly. The preparations on the test day might take an additional 1 to 1.5 hours.

Sometimes, opting for scientifically supported solutions can provide peace of mind, not just for the test but for your overall well-being.

Remember, the choice you make shouldn’t just be about passing a test; it should also prioritize your health and future.

Methods that don’t work for passing a hair drug test

Abstaining

One of the most common myths is that abstaining from drug use will clear the drug from your hair. However, this is not true. THC (the active ingredient in marijuana) is already deposited in your hair and cannot be removed by abstaining.

Additionally, even if you abstain, THC is present in body fat cells. When your body breaks down fat cells, THC is released into the blood and gets deposited into the hair.

Therefore, even if you abstain for 90 days, there is no guarantee that your newly grown hair will be clean.

Unless you give up drug consumption completely for at least 120 days, it won’t help you much. You will still get caught on such a test.

Bleaching your hair

Some online forums suggest bleaching your hair to pass a hair drug test, but this method is not very effective.

The success rate is less than 40% and can damage your hair.

Additionally, clinical managers are trained to look for tampering signs; if they notice that your hair has been bleached, it may raise suspicion.

Shaving your head

Shaving your head is another common myth that does not work. The sample collector can take hair from any other body part if you are bald.

While you can shave all your body hair, this will look very suspicious, and you may be fired or placed on probation while they wait for your hair to grow back.

Wearing a wig

Wearing a wig is another trick that does not work. The sample collector will discover that you are wearing a wig from a different hairstyle or synthetic hair samples.

Taking detox pills or drinks

Finally, some people believe that taking THC detox pills or drinks can remove THC from their hair. However, this is not true.

Pills and drinks cannot remove THC from hair, and no scientific evidence supports these claims.

Drug testing procedure

The hair drug testing procedure typically begins with a clinical manager checking the individual’s ID and explaining the process to them.

The manager will then take a hair sample from the back of the individual’s head, trying to be as discreet as possible.

The hair is typically taken using sanitized shears close to the root.

Since hair grows approximately 0.5 inches per month, the 1.5-inch sample taken by the manager will allow drug usage detection during the last three months.

The hair sample is then placed into a foil and then into an envelope, which is sent to a laboratory for analysis.

Depending on where the hair strand test is being performed, the sample may be analyzed in a lab or a hospital setting.

Sometimes, a workplace may use a kit to perform the test, which is then mailed to a laboratory for analysis.

The test results are typically back to the company within 3-5 business days.

It’s important to note that hair drug testing is a highly accurate method for detecting drug usage, with a detection rate of up to 90 days in some cases.

The test is also less invasive than other drug testing methods, such as blood or urine testing.

However, it’s important to follow proper procedures during the collection process to ensure accurate results.

Which employers require hair drug tests

It’s important to keep in mind that each employer has their own drug policies. However, there are certain industries that tend to require hair drug tests more frequently due to the high-risk nature of their jobs.

Here are some industries where hair drug tests are commonly required:

Trucking and Transporting

Trucking companies are responsible for transporting goods across long distances, often requiring their drivers to be on the road for extended periods.

As a result, they need to ensure that their employees are always alert and focused. Hair drug tests are considered to be the most effective way to screen for drug use, and many trucking companies already require their drivers to pass a hair drug test.

Some of the companies that require hair drug tests include:

AAA Cooper, USA Truck, Crete Carrier, Roehl Transport, Inc, Knight Transportation, TransAm Trucking, ABF Freight System, Western Express, Acme Truck Line, and Rush Trucking.

Construction

Construction work involves operating heavy machinery and working at heights, making it a high-risk industry. A lapse in judgment due to drug use can cause serious injuries or even fatalities.

To minimize workplace accidents, many contractors require their employees to pass drug screens, with hair drug tests deemed the most effective.

Financial Industries

Working in the financial industry involves making important decisions that can impact a company’s bottom line.

As a result, many employers in this industry test for drug use to ensure that their employees are making sound decisions.

A single misstep due to drug use can have severe consequences for a company’s operations.

Federal Workers

Although more than half of the US states have legalized the use of marijuana for medical purposes, it is still illegal at the federal level.

As a result, federal workers are required to observe federal rules and may be required to take and pass a hair follicle drug test.

Manufacturing and Shipping Warehouses

Working at a manufacturing plant or a shipping warehouse can be a fast-paced job that involves the use of heavy machinery.

Employees need to stay alert and focused at all times to avoid accidents. Therefore, it’s common for employers to test for substance use, and hair drug tests are considered to be the most effective way to screen for drug use.

Additionally, drug screens can help keep a company’s insurance costs low.

FAQ

How do the drugs get inside the hair follicles?

When you smoke weed or use drugs, the substances get into your blood. From there, they can travel to your hair follicles, where they can be deposited into the hair shafts.

Can I fail a hair drug test from second-hand smoke?

Yes, you can. Suppose you’re near someone who is smoking marijuana or using drugs.

In that case, the molecules can become embedded in your hair strands, producing a positive result on a hair follicle test.

Do all hair test shampoos guarantee a success rate in hair follicle drug tests?

No, not all hair test shampoos can guarantee a 100% success rate. However, the Old Style Aloe Toxin Rid Shampoo has a 99% success rate and is widely considered the best option on the market.

Why are detox shampoos so expensive?

Unlike regular shampoos, drug detox shampoos have a unique proprietary formula that can’t be duplicated in lower-quality shampoos.

The Old Style Aloe Toxin Rid Shampoo is the only detox shampoo that offers the highest success rate and holds a monopoly over the market.

Can the test identify the date of drug use?
