Many employers use hair follicle drug tests to determine employment eligibility and gain information about an individual’s drug use history.If you have an upcoming hair drug test, you may be feeling stressed about how you will pass. Fortunately, two reliable methods can be used to remove toxins like THC from your hair, in time for a hair drug test.
Let’s explore those two methods and discover the benefits and drawbacks of each one. By the end of this post, you should be confident in your upcoming hair follicle test and what you need to do to get a successful result.
What is a hair follicle drug test?
A hair follicle drug test is a test completed to determine if a person has used drugs in the last 90 days. To do this, three or four 1.5-inch hair samples are clipped from an individual’s hair, typically near the roots.
Why the roots? Well, whenever someone uses drugs, these substances travel through their blood and give them a high. Interestingly, each hair on your head grows out of a little pocket in the skin called a hair follicle, which has a tiny blood vessel feeding it. This blood vessel helps the hair grow by delivering nutrients.
Because these blood vessels are directly connected to the hair follicles, drugs that enter the bloodstream can end up in the hair. That's how drugs like weed can be found when testing hair.
Hair follicle drug testing can detect traces of marijuana, PCP, cocaine, ecstasy, and other opiates in each hair sample.
Understanding Hair Follicles
Here’s a table to understand how long weed stays in your system, depending on use.
| Weed Use & Exposure |
Detection Window in Hair Follicles |
| Single/ occasional use |
Up to 90 days |
| Moderate use (1-3 times/week) |
Up to 90 days |
| Regular use (4-6 times/week) |
Up to 90 days |
| Heavy use (daily) |
6 months or more |
How the Hair Drug Test Works
Here’s how hair follicle tests work so you know what to expect when it’s your turn to undergo this process.
- A hair sample will be taken from your scalp.
- The sample will be cleaned, prepped, and sent to a lab for testing.
- For accuracy, common hair test methods include the ELISA (enzyme-linked immunosorbent assay) and mass spectrometry.
- These two tests will determine if drug metabolites are present in the hair follicle.
- The results will be reported to the testing agency, then directly to your employer or healthcare organization.
| Fun Fact: Hair drug testing was first introduced in the United States in 1987, but scientists have reported finding drugs and other chemicals like arsenic in the hair follicles since the late 1800s. |
How to Pass a Hair Drug Test
Now that we have a clear picture of what a hair drug test is and what it entails, it’s time to explore your options for passing these tests.
Two methods are commonly used to pass hair follicle drug tests — the Original Macujo Method and the Jerry G Method. Both are multi-step processes requiring various household ingredients to remove any traces of the drug from the hair follicles.
Let’s discuss the Macujo Method and the Jerry G Method to pass a hair follicle test here.
The Macujo Method
The Original Macujo Method is a seven-step process that cleanses the hair of all the toxins and unwanted chemicals that may be present at any time. This method is highly popular among cannabis users because it’s extremely effective, boasting a 90 percent success rate when done correctly.
Here’s what you’ll need for the Original Macujo Method:
Original Macujo Method for Weed: Step-by-Step Instructions
Follow these instructions precisely to cleanse the scalp of any toxins successfully.
Step 1: Stop smoking (or vaping, eating edibles, etc.) marijuana immediately.
Step 2: Rinse your hair with warm water, ensuring you soak from root to tip.
Step 3: Pour the vinegar all over your hair, spending time massaging it into the scalp.
Step 4: Without washing off the vinegar, massage the Clean and Clear Shampoo (preferably the pink variant with salicylic acid) into the scalp, then put your hair in a shower cap for 1 hour.
Step 5: Rinse the hair with warm water using the Old Style Aloe Toxin Rid Shampoo after one hour. Do this twice.
Step 6: Avoid contact with your eyes; wash the hair with the liquid Tide. Scrub thoroughly until the hair feels clean.
Step 7: Lastly, wash your hair with the Zydot Ultra Clean Shampoo, thoroughly massaging it into the scalp for a final cleanse. Rinse with warm water.
The more times you complete this process, the better your likelihood of passing a hair drug test. We recommend completing the Original Macujo Method at least 3 times before your test, but some individuals do it up to 7 times to ensure a passing result.
Benefits of the Original Macujo Method
If you’re in a pinch and must pass a hair drug test ASAP, the Original Macujo Method is a popular and effective choice.
The greatest appeal to the Macujo Method is its ability to work within a tight timeframe. The Macujo Method can be performed just one day before your hair follicle drug test and still allow you to achieve the results you’re looking for.
Other benefits of the Orignal Macujo Method include the easy availability of the necessary products and avoiding harmful hair treatments like bleaching or dyeing. Using the Old Style Aloe Toxin Rid shampoo is the most important part of this process; the rest of the ingredients are there to put you in the best possible position to pass hair follicle tests.
| Pro Tip: For optimal results, keep all required ingredients readily available. This avoids the stress and expense of last-minute orders. By doing so, you won't have to deal with the uncertainties of shipping and delivery times, ensuring you’re always prepared even during a surprise hair follicle drug test. |
Drawbacks of the Macujo Method
The Original Macujo Method removes drug residues, such as marijuana metabolites, from the hair. However, it involves using potent products that can harm your hair, potentially hindering the growth of healthy follicles.
Despite these risks, many people consider the method worthwhile, particularly when facing a drug test for employment or to sidestep fines or legal issues. Caution is essential; exposure of these ingredients to your eyes or prolonged contact with your skin can lead to further damage.
The best way to avoid this is by using extra caution and taking time with each step.
Jerry G Method
The Jerry G Method involves using bleach and hair dye to remove any drug metabolites from the hair follicles. These harsh ingredients can forcefully open your hair follicles to clear any traces of marijuana and other drugs.
Here’s what you’ll need for the Jerry G Method:
Jerry G Method for Weed: Step-by-Step Instructions
Follow these instructions precisely to successfully cleanse the scalp of any toxins using the Jerry G Method.
Step 1: Stop using weed or any other substances 10 days before your drug test.
Step 2: Carefully bleach your hair to remove all drug metabolites from the hair follicles.
Step 3: Dye your entire head using permanent hair dye with ammonia.
Step 4: Shampoo your hair with Old Style Aloe Toxin Rid Shampoo.
Step 5: Wait ten days, then bleach and dye your hair again.
Step 6: On the day of your test, apply a baking soda paste to the scalp. Let sit for 15 minutes, then wash it out.
Step 7: Shampoo the hair with the Zydot Ultra Clean Shampoo.
Benefits of the Jerry G Method
For individuals with ten days to spare, Jerry G is a great method to ensure you pass your test. You won’t spend as much on the products required to complete the cleanse, and the items are readily available anytime.
Drawbacks of the Jerry G Method
The Jerry G Method might not suit those short on time, requiring at least 10 days to be effective. In contrast, the Original Macujo Method offers a quicker solution, possibly eliminating drug metabolites from your hair as soon as one day before your hair follicle drug test.
If you have sensitive skin, the Jerry G Method may not be the best choice to avoid an adverse reaction to bleach or hair dyes. Following this method may necessitate users to trim their hair due to the potential damage caused to the hair follicles, to encourage healthier regrowth.
The Macujo Method vs. Jerry G Method
As discussed, key differences exist between the Original Macujo Method and the Jerry G Method.
Original Macujo requires more ingredients and planning ahead to ensure you can complete the process effectively, but it gives you a lot of wiggle room because you can complete it the day before any hair drug tests. The products needed are more expensive than those required for the Jerry G Method, but with an efficacy rate of over 90 percent, it’s worth it!
The Jerry G Method isn’t quite as effective and requires more time. You’ll need to start the Jerry G Method ten days before your drug test to get the results you want. Both methods can damage the hair to some degree because of the strong products used.
| Did You Know: Drug screenings don’t test for THC; they look for the metabolites that cling to fat cells. Both methods target the metabolites in the hair to remove them completely. |
