Best Hair Detox Shampoos: Top Detoxifying Method To Pass Hair Follicle Test [2021]

Best Hair Detox Shampoo (blue ribbon 48)

Drug testing is becoming increasingly common in the workplaces these days. From the employers’ point-of-view, regular drug tests help them ensure that their employees will display good judgment at work and be more productive.

For you, however, if you’ve used drugs recently, these tests can spell trouble. Marijuana is the drug people have the most problem with, because, out of all the drugs, THC stays in your system for the longest period. After you’ve used it, there’s no reliable way of finding out how long it’ll take to completely filter out of your system and you'll be able to pass the hair follicle drug test, especially if you’re a heavy user.

So what do you do?

Well, if you want to keep your job, the answer is obvious: you detox. But there’s a lot of variety when it comes to detox products, and, since a lot hangs in balance, you want to know what your best option is.

We’ve already covered the best detox products to use if your company uses urine, blood, or saliva tests. But what about the best hair detox shampoos? We’ll be covering these today. But first, let’s look at the hair follicle drug tests themselves.

How Do We Pick Our Detox Shampoo Brands?

In order to settle at these 3 picks for the hair follicle drug test. We went through thousands of customer reviews who did a hair drug test, and settled on several picks for the hair follicle drug test. We bought these hair follicle detox shampoo, tried them out for ourselves, ran a ton of hair follicle drug tests, and settled on the ones we’ve mentioned above.

In addition to testing the hair follicle detox shampoo ourselves, we also rated them on how easy they are to purchase, what the customer support (or lack thereof) is like, and what other users say about them in their customer reviews.

That being said, let’s cover our top 3 picks for hair detox shampoos.

3 Best Hair Detox Shampoos to Treat Your Scalp [Reviews]

As we mentioned earlier, there are a lot of hair detox shampoos in the market, all of them claiming to be the best. That’s why, we’ve decided to test some of the best ones and made our picks in 3 different categories:

1. Best THC Detoxifying Shampoo: Old Style Aloe Toxin Rid Shampoo

2. Best THC Hair Detox Shampoo Based on The Value: Zydot Ultra Clean Shampoo

3. Fastest Detox Method To Pass Hair Follicle Drug Test: Rescue Hair Detox Shampoo

#1. The Old Style Aloe Toxin Rid Shampoo: Best Drug Detoxifying Shampoo

When you buy this shampoo, you’ll typically receive a sachet of Zydot Ultra Clean with it. Don’t get confused, you’re supposed to use both. Start using Old Style Aloe Toxin Rid at least 3-10 days before your drug test.

To use it properly, first use your regular shampoo, rinse, and then apply The Old Style Aloe Toxin Rid shampoo (take a dime-sized portion). Let it soak for 15 minutes before rinsing it and using your conditioner.

In case you’re short on time and don’t have 3-10 days, you can still use this Aloe toxin Rid hair detox shampoo. However, make sure to wash your hair at least 15 times in total with this shampoo beforehand with Old style Aloe Toxi Rid Shampoo (the more, the better); obviously, you’ll have to take multiple showers each day.

The most important thing to mention here is that while you’re detoxing with the Old Style Aloe Toxin Rid shampoo, you’ll have to abstain from using THC. You also cannot use your old comb or let your hair touch anything, including bedsheets or pillows.

On the day of the test, use the included Zydot Ultra Clean 2-4 hours before your test. It’s not strictly required, but it’ll increase your chances of passing the test. Afterwards, your hair should be free of any THC metabolites for at least a 6-hour window (Zydot Ultra Clean advertises a 24-hour window). During which you can easily pass the test.

The best thing about this Old Style Aloe Toxin Rid shampoo is how gentle it is on your hair while still thoroughly getting rid of weed metabolites. If your hair is usually dry, though, you should pair this with a good conditioner.

Now, to the million-dollar question: How well does it work?

We are glad to say that The Old Style Aloe Toxin Rid Shampoo passed our tests with flying colours. Even when we gave it a window of 3 days before testing, the hair drug test came clear. You’ll have to make sure that you strictly follow the included instructions that come with it, just like we did.

This is, by far, the best detox shampoo you can find on the market right now. It may not be the cheapest, but it’s a no-brainer if you want to maximize your chances of passing the test.

Consistently delivered the best results in our testing.

Gentle on your hair and scalp.

You can use it as your standalone detox shampoo without relying on any other product.

Includes Zydot Ultra Clean for use on test-day to maximize your chances.

Quick shipping available if your test is imminent.


Best used for light to moderate marijuana users. If you’re a heavy user, you’ll have to use this shampoo for longer.

It’s expensive.

Customer reviews

The first thing we noticed about this shampoo is that it has the highest proportion of positive reviews from its customers. Almost everyone who has used it has left a 5-star review.

Some of the reviews were from customers who had fewer than 3 days to detox using this shampoo, and even most of these customers passed the test. However, the longer you detox with this shampoo the better your chances will be (especially if you’re a heavy user).

Buying experience

Even on customer friendliness, we can rate Toxin Rid 5 stars. The website is easy to navigate and quick to load. The product page itself contains plenty of information, and, if you have any questions or issues, their customer service team is quick to respond and very helpful.

The company even offers quicker shipping options in the US, using which you’ll get the shampoo in 1 day instead of the usual 3 days.

#2. Zydot Ultra Clean Shampoo: Best Hair Detox Shampoo Based on The Value

Whereas Toxin Rid shampoo gives you a whole course of 3-10 days, depending on how much time you have and how frequently you use marijuana, Zydot Ultra Clean shampoo is only meant to be used on the day of the test. You could say that Zydot’s approach is more one-size-fits-all.

We should mention in the beginning that, if you’re a heavy user, Ultra Clean alone likely won’t work for you. For best results, you’ll have to use The Old Style Toxin Rid Shampoo for several days before using Ultra Clean on your test day.

For light to moderate users, you’ll have to abstain from using marijuana for several days. On your test day, use the shampoo and avoid using anything that has previously been in contact with your hair, including pillows, bedsheets, glasses, comb, your car’s headrest, etc. These objects will usually contain traces of THC metabolites and will reintroduce them into your hair.

The tricky part about this shampoo is that it’s meant to be paired with other detox methods. Whether you use home remedies, or pair it with detox products available in the market, you shouldn’t rely on this shampoo alone.

You’ll have to first pick a method that you want to use for several days before finally using Zydot Ultra Clean on test day. Afterwards, the shampoo should provide you a window of 24 hours during which you can pass the test.

Before testing this shampoo, we used the Macujo method over 10 days. You can use the same, or combine lots of different methods and products to increase your chances.

Moment of truth, how well does it work? We found that, using the Macujo method, it was possible for us to pass the test IF the test subject used marijuana 3-4 times per week. For heavy usage, the tests failed. There are a few user reviews of Ultra Clean saying that heavy users can pass the test if they mix a few methods, but your mileage may vary.

Cheap. It’s usually available for well under $40.

Designed to work with homemade methods.

Easily available in retail stores as well as multiple online stores (including Amazon).

It’s gentle on the hair and scalp.

Gives you a 24-hour window to pass the test.


It’s not a standalone product. Needs homemade methods or other detox products to be used for several days before the test. This ends up increasing the actual cost you’ll incur in your detox.

Likely won’t work well for you if you’re a heavy user.

Customer reviews

Customer reviews of Zydot Ultra Clean are quite positive. For light to moderate users, the detox shampoo works well; provided you supplement your detox process with the proper method and/or products.

Heavy users report having problems with this shampoo, though. Even in our testing, Ultra Clean couldn’t help us pass the test in case of heavy marijuana usage. Some chronic users said in their reviews that they had success if they combined multiple detox methods (sometimes with detox products) before using Ultra Clean.

Buying experience

The buying experience with this shampoo is great. It’s available through multiple channels, both online and in retail stores. So you’ll have no trouble getting your hands on it.

There’s plenty of information available on Zydot’s website on how you should use Ultra Clean, as well as where you can get it. However, the information doesn’t cover which methods you should use to detox until you get to the drug test day, when Ultra Clean is meant to be used.

Lastly, Zydot offers a money-back guarantee on its products if the shampoo doesn’t work for you; which is pointless when you think about it. Your career’s worth much more than the cost of Ultra Clean. But at least the option is there.

#3. Rescue Hair Detox Shampoo - Fastest Detox Method to Pass Hair Follicle Drug Test

Applied Sciences’s Rescue Hair Detox Shampoo is your best option if you suddenly get notified that you have a drug test within the next 2-3 days. As its name implies, the shampoo is meant to rescue you from emergency situations like these.

Like our previous pick, this one is meant to be used on the day of your drug test as well and contains only enough shampoo for a single detox session. But it promises far quicker, and better results, as long as you follow the instructions properly.

You’ll have to use a quarter bottle’s shampoo first, apply it thoroughly in your hair, let it soak for 5 minutes and then rinse; leave your hair damp and wait for another 5 minutes. After that, use the rest of the bottle, let it soak for 5 minutes for the last stretch before finally rinsing your hair.

Unlike our previous two picks, Applied Sciences suggests using no products after this one. Not even a conditioner or a hair gel. As usual, avoid getting your hair in touch with potentially contaminated surfaces and use a brand-new comb to style your hair.

How well does it work? Really well. It clears your hair of toxins in an hour and the effects last for more than 24 hours! In our testing, Rescue Hair Detox Shampoo even helped us pass the hair follicle test in some heavy use scenarios. But, to improve your chances as a heavy user, pair it with a few days of another detox method or product beforehand.

Affordable and works well as a standalone product.

One of the fastest acting detox shampoos.

More than a 24-hour window during which you can pass the test.


User reviews on this shampoo are lacking online.

Not sold directly on Applied Sciences’s website.

Customer reviews

As we’ve mentioned earlier, there’s a dearth of online customer reviews on this product. But the reviews that are available indicate that customers had the same experience we did in our testing.

The users indicated that this shampoo can also be used as your daily shampoo, as it’s very gentle on your hair and smells quite nice.

Buying experience

When it comes to detox products, Applied Sciences is a well-known name. However, while their website contains plenty of information on how you should use their detox shampoo, they don’t sell it directly.

For us, the Rescue Hair Detox Shampoo was locally available in Walmart. It’s hard to find this shampoo online; when you find a store selling it, they’re usually out of stock. Applied Sciences needs to step up its products’ availability, channels, and marketing.

When you do have questions, though, the company is available through both email and a toll-free number. They’re very responsive to your questions and reply to any email queries quickly.

Things to Consider Before Buying Hair Detox Shampoo: Buying Guide

When you go to your local store, you’ll find a ton of detox shampoos; all of them claiming that they can help you pass the hair follicle test. You should know that not all detox shampoos are created the same. Even on the off chance that these shampoos work, they can contain harmful ingredients that can do some real damage to your hair.

So how can you tell which detox shampoo to trust and which ones to avoid? Here are the factors that should guide your buying decision.

Company reputation

It’s easier than ever to check on a company’s reputation these days, thanks to the internet. Before you hand over your hard-earned money (and bet your career on a product), go online and do some research on the company that makes the detox shampoo.

If you find no (or mostly bad) reviews, avoid that product with prejudice. Like we mentioned earlier, there’s a lot hanging on the drug test and the last thing you want to trust is a shady brand.

Active Ingredients

The active ingredients in a detox shampoo are extremely important. Many shady companies include ingredients that will damage your scalp and hair. These ingredients can also poison you if you happen to get the shampoo into your eyes, nose, or mouth.

In addition, beware of products that don’t mention their ingredients anywhere, including their packaging and on the company’s website. Avoid them at all cost because there’s no good reason why a company should hide product ingredients from you.

You want a shampoo that’s gentle on your scalp and hair, contains natural ingredients and is safe to use, and tells you about all the included ingredients right on the product packaging.

Usage and procedure

These days, nobody has time to follow a 20-step process just to detox their hair. There are plenty of great hair detox products on the market that’ll get you the results you need without having to follow a tome of instructions to the letter.

Before you buy a detox shampoo, and commit to using it, make sure that its proper usage isn’t super complicated.


Cost is a major concern for us when buying anything. Most of us want the best bang for our buck, and the temptation to cheap out when buying a detox shampoo is very real. There are so many products, and all of them seem equally good on the surface while being priced differently.

However, consider the actual cost here if you cheap out and fail the drug test. At the end of the day, it’s not worth buying a cheap and/or shady detox shampoo just to save your money. Go with our best picks, or use your best judgment using the tips we’re mentioning here.

Effective time window

No detox shampoo will permanently get rid of THC metabolites in your system. They’ll give you a window during which your hair will be clean of any toxins. Eventually, the toxins that are still in your body will make it back to your hair through blood vessels and sebum production.

This effective window varies between detox products, and you should ideally use the one that gives you the most time to pass the test.

The type of hair and scalp you have

Your hair and scalp need to factor in when you choose a product. Not all products will suit all people. There are different products for oily scalp, dandruff, split-ends, damaged hair, etc. Then there’s the question of what type of hair you have. Is it curly? Straight? Wavy?

Account for these factors when buying a detox shampoo. Otherwise, you may end up damaging your hair and scalp.

What Happens When You Take Hair Follicle Drug Tests?

When you go through a hair drug test, a small sample of your hair measuring around 1.5 inches will be taken from your scalp using scissors. This sample will then be tested for various drugs, which include the following:








The test itself is divided into two steps:

1. Enzyme-linked immunosorbent assay (ELISA)

2. Gas chromatography–mass spectrometry (GC-MS)

We won’t get into the technical details about these two hair drug test. Suffice to say, if your hair drug test is positive for drugs in the first step (ELISA), it’ll be sent for further (and definite) analysis using GC-MS.

You might be wondering how long THC stays in your hair. Out of all the various tests, THC remains the longest in your hair. In fact, your hair can contain traces of THC up to 90 days after you start abstaining.

How to Pass The Hair Drug Test?

That 90-day figure can be quite intimidating. Don’t worry, there are ways you can pass a hair follicle drug test. We’ll briefly take you through them.

The best way is to use your body’s own natural processes for hair detox. If you know you’ve got more than 90 days before your drug test, start abstaining now and use hair follicle detox shampoo. To further maximize your chances to pass a hair follicle drug test, eat healthy (include lots of fruits and vegetables in your diet), drink plenty of fluids every day, and exercise are the best hair follicle detox measures.

In case you don’t have 90 days to go though this best hair follicle detox measure, and you're wondering if completely shaving your head bald before the hair drug test is a good idea, it isn’t. Not only will it look suspicious, your company will insist on taking a hair sample from your arms, legs, or anywhere else.

What other options do you have? Hair Detox shampoos. They’re different from regular shampoos because your regular shampoo can’t get rid of THC metabolites in your hair. Whereas hair detox shampoos are especially designed for this purpose.

FAQs About Hair Detox Shampoo:

1. How long does it take to get results back from a hair follicle test?

If your test comes back negative (meaning you pass the drug test) the results come back within 24-48 hours. A positive result takes at least 72 hours in total.

The reason for this discrepancy is that if your hair tests negative on ELISA, then it won’t be sent for a detailed analysis using GC-MS. ELISA can usually be done within 24 hours. If your test comes positive on ELISA, it’s sent for the second step and the lab runs GC-MS to rule out false positives and get a more accurate picture.

2. Which drugs can be detected using the hair follicle test?

The test is usually used to detect the following:











3. How accurate is the test?

The hair follicle test is generally very accurate. Before any testing is done, your hair sample is washed and tested for environmental contaminants that could end up polluting the results.

That being said, you should know that the first step of the hair follicle test, ELISA, is susceptible to false positives. Which is why your sample will be sent for GC-MS for a more accurate analysis.

4. Can I get a false positive on both steps of the hair follicle test?

It’s possible, although it rarely happens. GC-MS is far more accurate than ELISA and will rule out most false positives. But if you’re on prescription opioids, you can get a false positive even on GC-MS. Make sure to let the testers know that you’re on prescription meds if that’s the case; be aware that they’ll ask for a copy of your prescription.

5. Why do these shampoos only give me a time window during which I can pass the test?

As mentioned earlier, these shampoos only clean your hair and scalp from metabolites that would make you fail the hair follicle test. Your body still contains those metabolites, and that’s how they make their way back into your hair through your bloodstream and sebum production.

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

On average, your hair grows 0.5 inches every month. So a 0.5 inch hair sample taken from your scalp can detect drug use as far back as a month.

Typically, labs will take a 1.5-inch sample to test for drugs. A sample of this length can detect any drug use in the past 3 months. However, if your hair is long, and they decide to take a longer sample, that detection period can go up to years (0.5 inches for every past month).

7. Is it legal for my employer to demand a hair follicle test?

State laws can vary on the legality of demanding a drug test. In some tests, employers can do so; in others, they can’t. However, it’s perfectly legal for employers to fire someone for refusing to take a drug test. In most cases, even when a test is legally required, your written consent will still be taken beforehand.

8. Are DIY methods of detoxing your hair worth it?

The answer largely depends on the method (or methods) you use. There are reliable methods which won’t damage your hair; then there are methods which will not only make you fail the test, but also end up damaging your hair and scalp. Bleaching your hair is a pretty good example of the latter type.

We used the Macujo method in our testing with Zydot’s Ultra Clear shampoo and it gave us good results. Before you settle on a DIY method (or a combination of DIY methods) to use, do plenty of research to make sure what you’re doing is safe for your hair and that it works.

The most important thing when using any method or any product is to stop using marijuana as early as possible. The earlier you start abstaining, the better your chances will be.

9. If I fail the drug test, what do I do?

If the nightmare scenario happens and you do fail the hair follicle test, don’t panic; most employers will let you request a retest. Keep in mind that your sample for the retest might be taken immediately after you request it.

A pretty useful lifehack here is that if you think you’ll fail the drug test and you know your employer offers retests, keep detoxing using your chosen methods and/or products. A positive result from the hair follicle test takes at least 3 days, which will give you 3 extra days to detox your hair and clear the retest. If you happen to pass the initial drug test, no harm done.

Conclusion: Which Hair Detox Shampoo Should You Prefer?

When using any detox shampoo, you’ll have to make sure of two things. One, you’ll have to start abstaining as soon as possible. Two, you should strictly follow the product instructions that come with your shampoo.

We covered a variety of detox shampoos for three different cases today. If you can afford it and have several days before the test, The Old Style Aloe Toxin Rid shampoo will be your best bet. If you’re on a budget, use a DIY method in combination with Zydot’s Ultra Clean. Lastly, if you’re incredibly short on time, use Rescue Hair Detox Shampoo.

We hope this article made things a bit easy for you in terms of picking the best detox shampoo. Good luck!
