How To Pass a Hair Drug Test In 2024: Methods And Tricks

As for 2024, a hair drug test is the most accurate method for detecting traces of marijuana in somebody’s system. Large employers continue using various drug tests to ensure workplace safety. And, as far as they do it, millions of Americans want to know, how to pass a hair drug test. This task isn’t an easy one – hair follicle drug testing is complicated and very precise.

The trends of 2023, when more and Americans used cannabis, look set to continue in 2024. More than 20 states have legalized the usage of THC in one or another way – people are allowed to smoke weed here, but employers still didn’t change their drug policies. So, in order to avoid illegal restrictions on their rights, people are looking for ways to get around these annoying tests.

Understanding the Hair Follicle Drug Test

The hair follicle drug test has become a pivotal screening method in 2024, gaining prominence in various fields, especially employment. The government and big employers use it because of its precision in THC metabolites detection. Any drugs you’ve consumed become part of hair structure over time, and it’s really hard to get them out. Hard – but not impossible, when you have a good hair detox shampoo. But we’ll get to this later.

The Science Behind Hair Drug Tests

During this screening, the hair sample undergoes a process to extract drugs and their metabolites from within the hair shaft. This is often done using solvents, which break down the hair and release all the stuff from within it.

Gas Chromatography (GC) is a famous separation technique. Scientists use it to separate and identify different chemicals from a blend of compounds. In the context of hair drug testing, GC is used to separate the individual drug residues from your hair strand and all that it’s got inside.

Mass Spectrometry (MS) is another thing that they use in this process. After separation through GC, the individual compounds are sent into the mass spectrometer. MS is a technique that ionizes molecules and then measures the mass-to-charge ratio of the ions. This process provides highly specific information about the structure of the compounds.

The GC-MS system identifies the specific drugs or metabolites present in the hair sample based on their unique mass spectra. Quantification is achieved by measuring the abundance of these ions. This step helps determine the concentration of each substance.

The Wrong Name

Contrary to their name, hair tests for THC don’t examine any actual hair follicles. It focuses on the hair shaft to find the smallest traces of drug metabolites. The nomenclature can be misleading; so many people call it a hair drug test. This distinction is crucial for individuals undergoing such screenings to comprehend the process accurately.

How Long Do Drugs Stay in Your Hair

Lots of people ask a question: how long does weed stay in a hair follicle? The simple answer is: up to 90 days. Yes, those two joints you took a week ago can still be detected after 2-3 months!

However, it depends on many things: your BMI, your drug usage frequency, even your genetics and hair type. We’ll cover it below, in more detail. But anyway, the risk of drug residues detection in hair is very high during 90 days after the usage.

How The Hair Follicle Test Operates

1. You receive a notification like this: “You are scheduled to take a drug test, and you must come to the laboratory at X address, at Y hour”.
2. Collection of hair sample: A small sample, usually taken from the scalp, is collected. Usually they take 100-120 hair strands.
3. Laboratory analysis: The collected sample undergoes meticulous laboratory analysis, ensuring precision. Lab workers are looking for various metabolites using the GS-MS method described above.
4. Cutoff levels: They are some kind of thresholds that are indicating the minimum concentration of a drug metabolite that means a positive result. If the concentration is higher – you have a problem because the test result is considered positive.
5. Review by a Medical Review Officer (MRO):

The results are typically confirmed by a Medical Review Officer. He or she is a licensed physician with many years of expertise. No weed trace will avoid their sight.

1. Reporting the Results: Once the analysis is complete, their job is done. The results are sent to the entity that requested the test. It can be your employer or a legal authority. The results can be negative, if there are no drugs, or positive, if they’ve found some hidden traces of drugs. You wonder, how long does it take for hair follicle drug test to come back? Usually, 3 to 5 working days.

The Cutoff levels For Various Drugs

Drug Class	Screen Cutoff Level	Confirmation Cutoff Level
Marijuana	1 pg/mg	0.1 pg/mg
Amphetamines/Methamphetamines	300 pg/mg	300 pg/mg
Cocaine	300 pg/mg	300 pg/mg
Opiates	500 pg/mg	500 pg/mg
PCP (phencyclidine)	300 pg/mg	300 pg/mg

Who Can Be Ordered to Pass a Drug Test?

• Employment Screening: A job applicant for a safety-sensitive position in a transportation company is required to undergo a hair drug test as part of the pre-employment screening process.
• Probation or Legal Requirements: An individual on probation, as mandated by the court, is required to undergo routine drug testing, including a hair follicle test, to monitor compliance with legal restrictions.
• Professional Athlete Testing: A professional athlete participating in a major sporting event is subject to rigorous anti-doping measures, including a hair follicle drug test, to maintain the integrity of the competition.

Hair Follicle Drug Test Procedures

When we’re talking about a hair drug test, there are two main procedures. First way, your hair sample can be collected and tested in a laboratory. Second way: you can order an at-home drug test kit, cut your hair at home and send the sample to a lab.

Laboratory Hair Testing

Laboratory-based hair follicle drug testing is the most common and widely accepted method. If you choose this approach, a professional will collect a hair sample from your hair, usually near the scalp. After this, they analyze your hair and everything inside it. The laboratory uses some really sophisticated techniques such as Gas Chromatography-Mass Spectrometry (GC-MS) to detect and quantify specific drug metabolites within the hair shaft.

This method ensures accurate and reliable results due to obvious reasons. Laboratory tests are often used in employment screenings and legal proceedings due to their precision and standardized procedures. Also, this method is supervised, so the results are accepted in the courts.

At-Home Drug Testing Kits

Don’t want to waste your time going to the lab? At home hair drug testing kits are designed for people who prefer privacy and convenience! These kits typically include directions instructions for collecting a hair sample at home. Then you have to send to a laboratory for analysis. And – no, you cannot examine your hair at home. There are no chemicals in the kit – as well as no gas-spectrometer, of course.

While these kits offer a degree of anonymity and simplicity, their accuracy may be questioned compared to professionally administered tests. Results are usually provided directly to the individual in 5-10 days. At-home testing kits may be suitable for personal use or initial screening, but their results wouldn’t be accepted during any legal procedure.

Factors Influencing Your Hair Contamination

There are some things that influence the storage and retention of weed traces in your system. Those typically include your body mass index (BMI), your weight, you metabolism rate, your gender, and the type and frequency of your cannabis usage.

All of these things are highly important when we’re talking about a urine drug test. An occasional smoker could be clean in 5-7 days, while the urine of a heavy user will be “positive” for 30+ days. Different methods of consuming THC can also give different detection windows during the urine test.

But when we are talking about a hair drug test, all this stuff matters just a little more than the phase of the Moon in the day of testing. If you consume THC, after 5-7 days it will get into your hair. And it would be detected during the hair test for up to 90 days. The only thing that can affect this period is your hair growth speed.

A hair of a common human typically grows at a rate of 0.014 inches a day. This means your hair grows 0.1 inches in a week, 0.4-0.5 inches a month, and 5 inches every year. However, this can differ from individual to individual.

We should also notice that drugs can’t be detected in the hair instantly or a day after exposure. They can detect some weed in your hair only after 5-7 days. In the case of a workplace accident, a hair drug test wouldn’t be an appropriate choice.

Pre-Test Preparations: What To Do And What To Avoid

So, you’re a cannabis user, and you’ve been ordered to undergo this fearsome hair follicle drug test. There are some things that you should do. But what matters much more, there are things that you shouldn’t do in any case!

Things To Do Before a Hair Drug Test

Do Some Research 

Before undergoing a hair drug test, it’s crucial to understand the process thoroughly. And we’ve created this guide for this reason! Knowing what awaits you, how far back it can detect your weed usage, and some other tiny things can help you a lot.

Abandon Any Drugs

Cease any drug use immediately. The longer you stay clean, the better your chances of passing the test. Hair drug tests can detect substances for an extended period, so abstaining from drug use is essential.

Diet And Sport May Help

Adopting a healthy lifestyle can contribute to the detoxification process. Don’t expect it to work as a wonder. But some exercise, along with a diet rich in fruits, vegetables, and water, can help you in detoxing before a drug test.

Look For The Best Hair Detox Shampoo For Drug Test

Research and invest in high-quality hair detox shampoos specifically designed to cleanse the hair shaft from drug residues. These shampoos often contain special ingredients that help break down and remove THC residues. Old Style Aloe Toxin Rid is a great example of such a product.

Things To Avoid Before a Hair Drug Test

Don’t Panic 

Panicking can lead to impulsive decisions. Instead, remain calm and focused. Create a strategic plan that includes steps like detoxifying shampoos, abstaining from drugs, and adopting a healthier lifestyle. A well-thought-out approach is key to increasing your chances of beating this annoying test.

No Drug Usage

Continuing drug use is a guaranteed way to fail the hair drug test. Complete abstinence is essential in the weeks or days leading up to the test to ensure that no traces of substances are present in your hair.

No Medical Treatments

Avoid any unnecessary medical treatments or procedures that may interfere with the test results. Certain medications or treatments could potentially impact the outcome of the test. If you need to take some pills – consult with a healthcare professional.

No Poppy Seeds, CBD Oil, and Second-Hand Smoking

Refrain from consuming poppy seeds, using CBD oil, or being exposed to second-hand smoke, as these can lead to a false-positive result. You surely don’t want it, right?

No Cheating 

Don’t try to shave your head or dye your hair. Trying to cheat the test by such stupid measures will just lead to a failure. Test administrators and lab workers will detect these tactics easily, and you will fail with guarantee. In some states, you may even be prosecuted for trying to cheat in these ways. Stick to legitimate methods of preparation to avoid negative consequences!

How To Pass a Hair Drug Test: The Macujo Method

If you want to pass a hair drug test and you’re a cannabis lover, you need to get weed out of your hair. And it’s easier to say then to do – THC residues dig deep into your hair cortex and can’t be just washed out simply. However, there’s a solution for this case, and it’s called The Macujo Method. This approach will cost you some money, but the result would be worth it.

The original Macujo Method is a famous seven-step hair-cleansing procedure, widely known and beloved for its effectiveness for cleansing the hair from weed traces. The primary goal of this method is to open the hair cuticles, reaching the core — the cortex — and eliminating all the toxic metabolites present within. It is known as the supreme home detox method. Why? Because if used properly, it gives 99% of successful results!

What Do You Need For Macujo Method 

• Rubber gloves
• Shower cap
• Goggles
• Heinz vinegar
• Tide Liquid Laundry Detergent
• Clean & Clear Deep Cleansing
• Old Style Aloe Toxin Rid Shampoo
• Zydot Ultra Clean Shampoo

You can use any vinegar you want instead of Heinz. The same is right for laundry detergent and deep cleanse – the items we mentioned are just well-known and effective, so using them is a good option. But any equal alternatives will also work.

However, two detox shampoos, Old Style Aloe Toxin and Zydot Ultra Clean, can’t be replaced by anything else! These two are essential ingredients of The Macujo Method. We’ll write more about them below.

Macujo Method Steps

1. Step 1: Stop taking any marijuana or other drugs! The sooner you stop smoking, eating, vaping, etc., the sooner the remaining metabolites could leave your body. Seems logical, but some people forget about this step.
2. Step 2: Put on the goggles and gloves. Rinse your hair with warm or hot water. Make sure you soak your hair well, from roots to tips. Now you have to put Heinz vinegar into your hair. This thing may make your scalp sting. These tiny bits are OK.
3. Step 3: Don’t wash the vinegar from your hair, but instead massage Clean & Clear into your head. And yes, it may make your scalp sting even more. Now you have to take the shower cap on, and do something else for an hour. You have to wait and let them do their job.
4. Step 4: After an hour, thoroughly rinse your hair to wash all the vinegar and cleanser away.
5. Step 5: Get your Old Style Aloe Toxin Rid shampoo and wash your hair – twice.
6. Step 6: Now you have to wash your hair with Tide Liquid Detergent. You have to avoid any contact of it with your eyes – use the goggles! In this case, wash under the goggle strap too.
7. Step 7: And the final wash: use the Zydot Ultra Clean shampoo for it. After it, rinse with warm water.

All this hair drug detoxing process should be done at least three times. Some THC users repeat it even seven times for a sure negative on a hair drug test. But remember that it can be dangerous for your hair and scalp, so be wise and use protection for eyes.

The Jerry G Method

The Jerry G Method is another hair detox approach that involves the use of peroxide bleach and baking soda to break down the hair cuticle. This process also can aid in the removal of THC metabolites from the hair cortex. However, according to hundreds of reviews on the Web, the Macujo Method is much more effective.

This method was made as an alternative to the Macujo Method. A well-known weed user from a web forum called “Jerry G” created it in 2008. He offered a two-step process of bleaching and re-dying the hair with a 10-day gap. And Jerry G wrote that this helped him to pass a hair drug test with ease. Since then, the Jerry G Method, has gained widespread popularity.

What Do You Need For Jerry G Method

• 10 days before the test – so if you have 4 or 5, choose Macujo.
• Disposable Gloves
• Safety goggles
• An ammonia-based permanent hair dye kit
• Peroxide bleach – one bottle
• Baking soda
• A good detox shampoo. Here you can use your favorite brand, but anyway we recommend Old Style Aloe Toxin Rid

Jerry G Method Steps

1. Stop using any drugs
2. On the first day, bleach your hair. Wear the protection!
3. Use the ammonia-based permanent hair dye. If you’re not an expert in bleaching and dying, visit a salon or call a friend.
4. Use Aloe Toxin Rid or other detox shampoo, wash your hair. Don’t use a blow dryer after this: your hair is already weaker then always.
5. After 10 days, do steps 2 and 3 again. If you don’t have this time, repeat the process on the last day before your test.
6. On test day, put baking soda on your hair. Massage it thoroughly, don’t forget the scalp. Leave it for 15 minutes, rinse twice. Baking soda will help you neutralize the acids.
7. Wash again with Aloe Toxin Rid – clean any remaining THC metabolites.
8. Rinse your head very well, let it dry. Again, no hair dryers.

That’s all. As you can see, the process is different and requires 10 days – if your clock is ticking, stick to Macujo Method. Jerry G is an interesting approach, but the risks of damaging your hair are higher. And bleaching is known to damage the hair badly sometimes.
