    ...I just wanted to say thank you! I passed my test and I'm able to provide for my family with the best job I've ever been given the opportunity to work! It worked perfect! I actually was sent to a second testing facility which added two hours to my 'hold time' and had no temp changes! Thanks again!...

    ...I really wish I would have found your products before I used synthetic urine and failed. =( There are so many success stories on forums and the internet from people who have succeeded by using synthetic, but I guess those days are long gone. I knew better, but didn't listen to my better judgment. My test results came back "inconclusive" when I used synthetic...

How to Pass a Hair Drug Test Using the Macujo Method - Step by Step Guide

Pass a Hair Drug Test With Macujo Method (INFOGRAPHIC)

Attitudes to the use of marijuana, for medical reasons or otherwise, have rapidly changed over the last 10 or so years. With the FDA’s recent approval of a cannabis-based drug to treat two types of epileptic syndromes, you’d think that the US federal government would at least recategorize marijuana.


Drug tests are still mandatory procedures for many places of work, and the reality is that you, a marijuana user, are interested in acquiring or keeping a job. Often, offices will administer urine drug tests, but hair follicle tests are also a popular method of drug testing, as traces of certain drugs are detectable in hair for a longer period in hair follicles than they are in urine.

Have no fear. There are ways to pass a hair drug test without completely shaving all your head and body hair off.

Enter the Macujo method, often shortened to the “Mac method.”

While urine drug tests typically screen for drugs taken within the last few days or weeks, hair follicle tests are often used to detect drug use within the last 90 days. So how does a hair follicle drug test actually works?

THC metabolites travel through your bloodstream and then are stored in your hair. A lab technician will come and cut anywhere from 100 to 120 strands of hair at least 1.5 inches long from your head, collected from the root. (The hair is collected from different parts of your head to prevent any bald spots or funky haircuts.)

If your hair is too short, or if you’re bald, body hair is used instead.

Now, if you don’t want to shave your head and wax off all your body hair to avoid being tested (a method that is decidedly less than subtle), you’ll probably want to try some detoxing methods to wash the THC-COOH (a THC metabolite) out of your hair.

There are a few effective DIY methods to do this, and one of the most effective hair detox methods is the Macujo hair-cleansing method.



The Macujo (or “Mac”) method is a seven-step hair-cleansing procedure, favored by many for its efficacy and convenience. What you’re aiming for with this method is to open up your hair cuticles to get to the hard part in the middle, which is the cortex, and flush out all the little metabolites swimming around in there.

The Macujo drug-detox method is by far more efficient for flushing chemicals out of your hair than home remedies like vinegar and salicylic acid soaks are; this Mac daddy of all home detox methods reportedly works about 90 percent of the time. That’s a pretty good number.



The Macujo method instructions are pretty easy to follow. First, you’ll need to gather the following items:

pass a hair drug test macujo materials

  • Rubber gloves

    Rubber gloves to protect your hands are always a good idea when handling chemicals.

  • Shower cap

    Use a shower cap when you don’t want your wet hair get in the way of your activities while you wait for the vinegar and the shampoo to work their magic.

  • Clean & Clear Deep Cleansing

    Clean & Clear Deep Cleansing has salicylic acid, which is the stuff you want in your hair to help flush out the chemicals. You can also get other shampoos that contain salicylic acid, but Clean & Clear Deep Cleansing is the most widely used by people who swear by Macujo cleansing.

  • Heinz vinegar

    You can find Heinz vinegar pretty much anywhere in the world, in any grocery, no problem. Heinz vinegar has a good acetic content, which is at about 5 percent.

  • Tide Liquid Laundry Detergent

    Also pretty readily available in grocery stores everywhere around the world.

  • Old Style Aloe Toxin Rid Shampoo

    Here’s where it starts to get a little tricky. You specifically need the original/old-style formula of the Aloe Toxin Rid Shampoo. Be careful of fake formulas, as they will not work. Always buy Old Style Aloe Toxin Rid Shampoo from reputable sources.

  • Zydot Ultra Clean

    Zydot Ultra Clean has been misunderstood for some time now. It’s an important part of the Macujo drug detox but is not as effective on its own. Buy Zydot Ultra Clean from reputable sources too, as fake formulas can result in disaster.



Once you’ve got all your ingredients, your gloves, and your sink, you’re ready to begin the first step of your Macujo drug detox.

Step 1: Once you learn about your drug test, or suspect that you’ll have to take a drug test in the near future, stop smoking pot. The sooner you stop smoking (or eating, vaping, etc.), the sooner the toxins can fully break down the remaining metabolites in your body.

Step 2: Over the sink, rinse out your hair with warm water. Make sure you thoroughly soak your hair from root to tip. After this, you’re ready to put Heinz vinegar in your hair. This may make your scalp sting a bit. Don’t worry; this is normal.

Step 3: Without removing any of the vinegar from your hair, massage Clean & Clear into your scalp. This’ll make your scalp tingle even more. Again, breathe. Put your hair in a shower cap, and go distract yourself with something while you wait an hour for the vinegar and Clean & Clear to do its job.

Step 4: After an hour, rinse your hair with warm water.

Step 5: Wash your hair with Aloe Rid shampoo. Do this twice.

Step 6: Now it’s time to wash your hair out with Tide Liquid Detergent. Scrubba-dub until your head feels absolutely clean. Important: avoid any contact with your eyes. Goggles may be worn if you want to make sure your eyes are safe, but you want to remember to get under the goggle strap too.

Step 7: The final step is to use the Zydot Ultra Clean shampoo. Again, rinse with warm water.

It’s really important to repeat this process at least three times. Many even say that, for a sure negative on your drug test, you may even want to try doing this seven times.



As with any detox method, the Macujo drug detox method has its pros and cons. The biggest downside of the Macujo method is the cost; getting enough shampoo to last you three to five washes can set you back a little bit.

However, if you really need to pass your drug test, the Mac method has proven to be at least 90 percent effective, and it may just be worth the cost anyway.

The Macujo method won’t work no matter how many times you wash your hair if you use fake OG Aloe Rid or if you don’t use the original old formula Aloe Rid. Remember, also, that it’s important to repeat the steps at least three times. Even up to five. Getting those cuticles open can take a long time, so be thorough and be patient.

It’s worth noting that the Macujo hair-cleansing method works for some hair types more than others. It reportedly works quite well for thin, light hair, but not as much for darker, thicker types of hair.



To be safe, you’re going to want to clean your hair several times throughout the week or weeks before your drug test. Use the recommended, original shampoos. Do it the night before and the morning of your drug test too.

Just in case your employers may want to test for drugs in your urine too, you may want to stop taking cannabis immediately after you learn about any upcoming drug tests. Exercise and diet are also key for processing THC out of your system, as it’s stored in fat.

It’s always a good idea to drink plenty of fluids and add an herbal supplement to the mix to really flush all the toxins out of your system.

Stay hydrated out there, guys, and remember: breathe!
