Score: 4 out of 5, B. It is very difficult to clean the hair shaft. This product could work as part of the Macujo or Jerry G methods. It is not likely to work alone to pass a hair sample drug test.

  • Shower caps
  • Pink Clean and Clear acne wash

  • Goggles
  • Disposable Gloves
  • White vinegar
  • Warm water
  • Ultra Clean by Zydot shampoo

The Macujo Method is a famous method for flushing drug metabolites out of the hair shaft. 1.5 inches of the hair closest to the scalp will be tested during a hair drug test. Studies have shown damage to the hair shaft, mostly by bleaching and dyeing, will reduce detectable drug metabolites. It reasons that the access to the hair shaft produced by putting all of these substances in the hair can also get drug metabolites out of the hair. We are only describing the process, we are not advocating that you do this. Using any of these methods can cause damage to the hair, scalp, or allergic reactions which could be uncomfortable or dangerous.

Directions to flush detectable drugs from Hair using the Macujo Method

  1. Rinse your hair well.
  2. Put the white vinegar in your hair. Leave it in.
  3. Put the Clean and Clear acne wash in the hair on top of that. Make sure you get it down to the 1.5 inches of hair closest to the scalp as this is the only hair that is going to be tested.
  4. Now put on a shower cap and let it sit for thirty minutes.
  5. Rinse it all out, then follow the instructions for shampooing with Folli Clean. You might use your Zydot first, then follow that with the Folli Clean. It’s not clear that Folli Kleen is a shampoo. It’s described as a deep cleaner, and suggests on the instructions you should use a regular shampoo first. So, it’s kinda like a conditioner as well as a shampoo and deep cleaner.
  6. Put a few drops of Tide in the hair and shampoo with it.
  7. Shampoo again with Zydot, follow that with Folli Kleen.
  8. Do this 3 times on the day before the test, and one time the day of the test. It will likely get at least some drug metabolites out of your hair. Unfortunately, the studies show, the more fried your hair is, the more drugs are gone so you might have to damage the hair in order for this to work. Good luck.

Another method is the Jerry G method or bleaching and dyeing method. This method actually has a scientific experiment behind it. One study abstract states, “Bleaching and perming reduced all cannabinoids concentration in hair; THC was more affected than THC-COOH, CBN, and CBD,” (Elsué and Yegles).

Using Folli Kleen with the Jerry G Method. Step by step guide

  1. Cease using drugs ten days out from the test if possible.
  2. Ten days before the test, bleach, and dye the hair. Make sure the bleach contains ammonia.
  3. Wash your hair with the shampoo recommended on the dye package, then use Folli Kleen Deep cleanser.
  4. On the day before the test, repeat bleach and dye, wash with shampoo and Folli Kleen.
  5. On the day of the test put a baking soda paste in your hair and leave it in there for 15 minutes. Shampoo with any good shampoo, follow that with Folli Kleen.
  6. The drug residues in your hair will be reduced. Note, you need to dye your hair its natural color as they may refuse to test hair that is wildly dyed.

Q&A about Folli Kleen

What’s special about Folli Kleen compared to the products?
It’s not as expensive as a product like Old Style Aloe Toxin Rid and it can be used in the Macujo Method and Jerry G method without having to spend over $ 200 for Toxin Rid.
What does it do?
We are unable to discover what are the active ingredients, but the shampoo and/or conditioner, as well as deep cleanser, is supposed to be able to get rid of and/or oxidize drug metabolites in the hair shaft. Since it is recommended one uses a shampoo before using Folli Kleen, that means it is a little more than a shampoo or conditioner, but a deep cleaner of the hair shaft. It contains vinegar and lots of fruit and herbal extracts.
Is it gonna work for weed, for opiates, and for cocaine?
If you use the Jerry G method, for example, experiments show reductions in THC and other drug metabolites in the hair shaft closest to the scalp.
What is it gonna cost me?

4 out of 5, B

Stinger Detox is well-trusted and its online presence is transparent. It is widely available. It’s a cost-effective replacement for Old Style Aloe Toxin Rid. Used with a bleaching and dyeing method, it will surely reduce drug metabolites in the hair.  For this reason, we give it a B. However, used alone, without a cleaning method, it would not be expected to significantly reduce drug metabolites all by itself.
