Today, I’m diving into a topic that might be crucial for many – selecting the best detox shampoo for hair drug test.

Let’s face it, you want a shampoo that’s effective and guarantees results without going to extremes. No bleaching, no full-body shaving, no harming your hair or scalp, and certainly no juggling multiple products.

Plus, you probably don’t want to spend a fortune, especially when you’re gearing up for a job opportunity.

My goal is to guide you on how to pick the right shampoo and use it effectively for a hair follicle drug test.

If you’re just here for the list of the best shampoos and not interested in how detox shampoos work, feel free to skip to the next section.

Do detox shampoos work for a drug test?

Yes, the effectiveness of detox shampoos for drug tests is backed by science.

However, it’s crucial to note that not all purifying and cleansing systems work. Specific drug test detox shampoos have been proven to effectively remove drug metabolites, including those from marijuana, cocaine, and morphine.

Research Summary from NCBI: A study from the National Center for Biotechnology Information (NCBI) explored the efficacy of detox shampoos in removing drug metabolites from hair. This research confirmed that specialized detox shampoos can play a significant role in cleansing hair of these substances.

Research Summary from ResearchGate: Another study, available on ResearchGate, focused on the Ultra Clean shampoo. This study provided evidence of the shampoo’s ability to reduce drug concentrations in human hair, underscoring its potential usefulness for those undergoing hair drug tests.

Research Summary on ETG from PubMed: Regarding ETG (a metabolite indicative of alcohol consumption), a publication on PubMed highlighted that certain detox shampoos can effectively cleanse this substance from hair.

An interesting find from these studies is that hair treatments, including the use of detox shampoos, couldn’t be visually detected.

While bleaching may be more effective, it’s also more harmful, damaging both the scalp and hair.

So, if your goal is to pass a hair follicle drug test without damaging your hair, opting for a hair detox shampoo is a wise choice.

And with that, this concludes our boring sciencey section. Now, let’s move on to the more practical aspects.

What to look for when selecting the best shampoo for passing a hair drug test

In this section, I’ll guide you on how to sidestep marketing gimmicks and choose a hair detox shampoo that actually works for a drug test.

I’ll also explain the criteria used in selecting the shampoos on our list and why these are crucial for passing a hair drug test.

Is the product suitable?

The market is flooded with many detox shampoos, but most users don’t need them for removing drug metabolites.

For many manufacturers, the term “detox” is just a marketing strategy. These shampoos often aim to restore hair structure and add shine, but that’s not what you need.

You require a shampoo specifically designed to remove drug metabolites from your hair, capable of penetrating and dissolving these substances within the hair structure.

In our list, we’ve focused on products that genuinely remove THC and other drug metabolites.


Some shampoos use aggressive ingredients, like bleach, to dissolve drug metabolites, but these can cause extreme damage to your hair and scalp.

Methods like the Macujo method, which involves using laundry detergent and vinegar, are harsh and risky.

Users have reported significant scalp irritation and hair damage. Remember, a damaged scalp or hair might raise suspicions during the testing process, prompting the tester to use hair from another body part.

So, choose a shampoo that’s effective but gentle on your hair and scalp.

Bottle size

The amount of shampoo you’ll need varies. The frequency of drug use dictates how often you should use the shampoo. For optimal results, it’s recommended to use the shampoo at least 15 times before your test.

Unlike urine tests, where you can self-test with a strip, hair drug tests don’t offer such a luxury.

So, it’s better to err on the side of caution and use the shampoo multiple times. On average, people use about 10 ml of shampoo per wash. Therefore, aim for at least 150 ml of shampoo, especially if you have long hair or dreads.

Our list includes products with sufficient quantity to help you pass the test.

Brand reputation

It’s crucial to check reviews, specifically those related to drug testing. Many detox shampoos have positive reviews for improving hair appearance, but you need proof of their efficacy in passing drug tests. For each product on our list, we’ve researched and included those with a proven track record of success in drug tests.

Best hair detox shampoos for a drug test

There are only a handful of reliable drug test detox shampoos on the market that genuinely work.

The industry is challenging to navigate due to moral and legal considerations.

However, some companies market regular detox shampoos as drug test detox shampoos, exploiting the fact that customers are unlikely to file complaints due to the sensitive nature of the product’s use.

Our list only includes reliable shampoos that have been proven to effectively remove drug metabolites from hair and help pass a drug test.

Old Style Aloe Toxin Rid Shampoo – Best Detox shampoo for hair drug test

old style aloe toxin rid shampoo

Topping our list is the Old Style Aloe Toxin Rid Shampoo, renowned for its effectiveness in removing drug toxins.

While this product was initially designed to cleanse the hair of contaminants, it has proven exceptionally adept at eliminating drug toxins too, making it an excellent choice for both moderate and chronic weed users.

Praised for its guaranteed results, this shampoo can function as a standalone product. Nevertheless, it’s often sold in conjunction with Zydot Ultra Clean for the optimal hair cleansing effect.

The deep-cleaning formula is gentle on your hair and scalp while removing toxins such as THC, COC, MET, and others.

Formulated with aloe vera and a wealth of natural conditioners, this shampoo prevents drying, ensuring your scalp remains hydrated, healthy, and happy. A single 5-ounce bottle provides multiple washes. Moreover, you can rest assured knowing that this product is entirely legal.

The Old Style Aloe Toxin Rid Shampoo has numerous customer success stories and consistently receives great reviews. Despite a higher price point of $230, it’s the only shampoo we can wholeheartedly recommend if you’re looking for guaranteed results. This shampoo can also be used in Jerry G or Macujo detox methods.

When and how to use

The ideal time to start using this shampoo is 3-10 days before your test, and its effects last for about 36 hours.

If you don’t have as much time, multiple showers daily will help. During each wash, let the shampoo lather in your hair for 10-15 minutes for the best results. Make sure to use the shampoo 15 times before your test. Here’s a step-by-step guide:

Remember, most toxins are found in the scalp. So, focus on removing all those older layers of oil.

Zydot Ultra Clean Shampoo – Most Affordable

zydot ultra clean

Our second recommendation is the Zydot Ultra Clean Shampoo. While it might not be as effective as the Old Style Aloe Toxin Rid Shampoo for regular marijuana users, it’s a fantastic choice for light users.

This shampoo won’t damage your hair or cause any scalp discomfort. Its affordable price tag also makes it a popular choice among consumers.

The Zydot Ultra Clean Shampoo is designed to expose the inner hair by removing external barriers. It then penetrates the hair shaft to dissolve and remove impurities.

Additionally, this product helps manage tangles, improves sheen, and boosts manageability. However, it can be a bit complicated to use and may require up to 45 minutes of your time.

When and How to Use

The best time to use this shampoo is on the day of the test, and the effects last for approximately 5 hours. You only need to use it once, and it costs just $35.99. While it can work as a standalone product, it gives the best results when used in combination with other products.

Macujo Aloe Rid Old Formula Shampoo

Another alternative worth considering is the Macujo Aloe Rid Old Formula Shampoo, identical to the Nexxus Old Formula detox shampoo. It’s particularly useful for moderate users and fits well into the Macujo hair cleansing method.

One peculiar aspect is the lack of reviews on the website, which may raise some eyebrows. Nevertheless, this product comes with the advantage of next-day shipping availability. The Macujo Aloe Rid Old Formula Shampoo is priced at $165, making it a moderate investment for those seeking an effective solution.

Stinger Folli-Kleen Intense Hair Cleanser


For those on a tight budget, the Stinger Folli-Kleen Intense Hair Cleanser might be an appealing option. While the reviews for this product are not overly positive, it’s FDA registered and made in the USA, providing some assurance of its quality. All the ingredients used are naturally found, which could be a comforting factor for some.

This cleanser might be a viable choice for light users willing to take a bit of a risk. The product can be purchased for the modest price of $29.99.

High Voltage Detox Shampoo

High Voltage Detox Shampoo

If budget is a significant concern, the High Voltage Detox Shampoo is the most economical choice available. However, its low price tag of just $12 does hint at its efficacy, as the product has received less than stellar reviews.

It might work for individuals who have only used weed once, but relying on it for regular or heavy usage might be a gamble. As always, when choosing a detox shampoo, consider your needs, usage patterns, and the level of risk you’re comfortable with.

Ultra Cleanse Shampoo

Ultra Cleanse Shampoo

The Ultra Cleanse Shampoo is another detox product available in the market. It comes with mixed reviews from users, leaving some satisfied while others found it lacking in effectiveness. Although the product claims to provide a deep cleanse, its inconsistency in delivering reliable results leaves room for improvement. For this reason, we suggest using Ultra Cleanse Shampoo with a measure of caution.

Omni Cleansing Shampoo

Omni Cleansing Shampoo

Omni Cleansing Shampoo is a detox product that aims to help individuals pass hair drug tests. While it’s convenient to use, reviews and user experiences suggest it might not be as reliable as one would hope.

The inconsistencies reported by users raise questions about its overall effectiveness. If you decide to give Omni Cleansing Shampoo a try, keep in mind the potential uncertainties associated with its performance.

How to use detox shampoo to pass a hair follicle drug test: step by step instructions

Navigating a hair drug test can be tricky, but I’m here to help. Let me walk you through how to use Toxin Rid Old Style Aloe Shampoo along with Zydot Ultra Clean Shampoo for the best chance of passing your test.

Instructions for Regular Users

If you’re a light or occasional user, you might get by with just using Zydot Ultra Clean Shampoo on the day of the test. However, for regular users, here’s what you need to do:

  1. Regular Usage: Start using the shampoo every day before your test, ideally 3-10 days in advance. If you’re short on time, consider taking multiple showers a day.
  2. Application Time: During each wash, apply the shampoo and let it stay lathered in your hair for about 10 to 15 minutes.
  3. Frequency: Aim to use the shampoo at least 15 times before your test. This ensures the most effective results due to the complexity of removing drug metabolites from the hair shaft.

Day of the Test: Using Zydot Ultra Clean

  1. Step 1: Wet your hair thoroughly. Apply half of the Zydot shampoo and massage into your scalp and hair for 10 minutes. Rinse well with lukewarm water.
  2. Step 2: Apply all of the purifier, massaging it into your scalp and the hair closest to it. Comb through your hair and leave it on for 10 minutes before rinsing.
  3. Step 3: Repeat Step 1 using the remainder of the shampoo.
  4. Step 4: Apply all of the conditioner, massaging it into your scalp and hair. Leave it in for 3 minutes, then rinse well. Style your hair as usual.

Tips for passing a hair drug test

Stop Drug Use: Cease using drugs at least 48 hours before starting the shampoo regimen to prevent new metabolites from entering your hair.

Avoid Contamination: Steer clear of items that have been in contact with your hair, such as pillowcases or hats, to prevent reintroduction of toxins.

Timing: Act fast; after about three days, drugs will be deposited into newly grown hair shafts.

Homemade solutions for hair follicle test

The Macujo method

What you’ll need

Step-by-step instructions

  1. Protection: Wear gloves and goggles for safety.
  2. Wet Your Hair: Make sure it’s damp throughout.
  3. Vinegar Application: Massage white vinegar into your hair and scalp.
  4. Astringent: Apply the Clean and Clear Astringent without rinsing out the vinegar.
  5. Cover and Wait: Use a shower cap and wait for 30 to 45 minutes.
  6. Rinse: Thoroughly rinse your hair with warm water.
  7. Shampoo: Wash your hair with the Aloe Toxin Rid Shampoo.
  8. Detergent Wash: Carefully wash with a small amount of Tide detergent.
  9. Repeat as Needed: This process can be repeated multiple times.

Jerry G method to pass a hair drug test

As an unbiased guide, let me introduce you to the Jerry G method, another approach some people use to pass a hair drug test. Just like the Macujo method, this one’s a bit intense, so let’s gear up for the details.

What you’ll need:

Step-by-step instructions:

  1. Safety First: Don your gloves and goggles. The chemicals involved are pretty harsh and can be irritating.
  2. Dye Your Hair: Apply an ammonia-based permanent hair dye. This process is believed to help break down the hair cuticle, potentially releasing drug metabolites.
  3. Shampoo Post-Dye: After dyeing, wash your hair well with the detox shampoo. It’s important to rinse thoroughly to remove all dye residues.
  4. Air Dry: Let your hair dry naturally. Avoid blow-drying to prevent further damage.
  5. Waiting Period: Give your hair and scalp a 10-day break before repeating the process. This is crucial for recovery from the chemical exposure.
  6. Repeat: After 10 days, dye your hair again and wash it with the detox shampoo.
  7. Baking Soda Treatment: The day before your test, apply a baking soda paste to your hair and scalp. This is believed to further open the cuticles.
  8. Final Rinse and Shampoo: Rinse out the baking soda and wash your hair one more time with the detox shampoo.


Considering the risks and efforts involved with these methods, I’d recommend using Toxin Rid Old Style Aloe Shampoo in combination with Zydot Ultra Clean as the most effective and reliable solution for passing a hair drug test. For light users, Zydot Ultra Clean alone might suffice.

It’s crucial to think about the consequences of failing a drug test. These decisions should not be taken lightly. Opting for the easy way out or settling for less effective methods could have significant repercussions. Remember, passing a drug test is not just about beating the test; it’s about making choices that ensure your safety and well-being too. Stay informed, stay safe, and good luck!

FAQs about hair detox shampoos

In this section, we’ll address some of the frequently asked questions about hair detox shampoos and related topics. As always, my aim is to empower you with knowledge so you can make the best decisions for your situation.

How long does detox shampoo last after you wash your hair?

The effects of detox shampoos can vary. For instance, Zydot Ultra Clean Shampoo remains effective for up to 5 hours after a single use. On the other hand, Old Style Aloe Clarifying Shampoo by Toxin Rid can keep your hair clear until you ingest weed again.

Does Selsun blue help pass a hair drug test?

No. Selsun Blue is a Medicated Anti-dandruff Shampoo with Menthol. It is not designed to detox hair drugs and thus, won’t help you pass a hair drug test.

What drugs do hair follicle tests detect?

Hair follicle tests can detect a range of drugs including Amphetamines, Methamphetamines, Marijuana, Cocaine, PCP, Xanax, Ecstasy, Fentanyl, Opiates, and Methadone.

Will bleaching your hair pass a hair follicle test?

Bleaching can reduce the presence of drug metabolites in your hair by between 40% and 80%. However, it’s a process that can damage your hair and scalp, and you’ll still need to use a detox shampoo for the best results. Labs are increasingly aware of bleaching as a method to circumvent drug tests, so if you turn up with bleached hair, they may ask for a different sample.

How far back can a hair follicle test detect drug use?

A hair drug test typically examines a 1.5-inch-long hair sample, which corresponds to about 3 months of growth. However, drug metabolites stay in your hair until it’s cut, meaning a longer hair sample could detect drug use for several months in the past.

Can you pass a test by bleaching your hair?

As mentioned above, bleaching can help reduce the presence of drug metabolites, but it’s not a foolproof strategy. It can damage your hair and scalp and you’ll still need to use a detox shampoo. A lab technician may also request a different sample if you arrive with bleached hair.

Is there anything I can do at home to pass a hair follicle test?

The most important thing you can do at home to increase your chances of passing a hair drug test is to stop using drugs. New metabolites are deposited into the hair each time you use, so cessation is key.

Is the hair follicle drug test accurate?

Yes, hair follicle tests are accurate. They aren’t triggered by second-hand smoke, as passive drug exposure doesn’t cause your body to contain the metabolites used to detect drug use.

Can employers legally enforce a hair follicle test?

While hair drug tests are legal, they’re also expensive and not commonly used by employers. Mostly, hair follicle drug tests are used for legal and medical purposes.

Can a lab determine when the drugs were taken?

Yes, a lab can potentially determine the timing of drug use by examining the distribution of drug metabolites along the length of a hair sample. However, this method is costly and thus, not typically used.
