Quick summary

So, is Old Style Aloe Toxin Rid Shampoo effective?

Yes, it is.

This shampoo is a legal method to cleanse your hair of substances like marijuana (THC), alcohol (ETG), cocaine (COC), morphine, and methamphetamine metabolites.

Scientific research supports its effectiveness.

However, if you’re a light user, it might be more than you need. There are cheaper hair detox shampoos available for passing a drug test.

It requires multiple applications, so make sure you have enough shampoo.

I’ll explain how to measure the right amount and provide detailed guidelines on its use.

Is Old Style Aloe Toxin Rid Shampoo effective for drug tests?

Studies have shown that treatments with propylene glycol, a key ingredient in Toxin Rid Old Style Aloe Shampoo, are effective in removing drug metabolites from hair.

This shampoo has shown high efficacy in eliminating traces of marijuana, cocaine, and morphine metabolites.

The research study focused on the manipulation of tetrahydrocannabinol (THC) concentrations in hair samples through the use of various commercially available products.

Among the products tested, bleach disinfectant and shampoo with propylene glycol were particularly noteworthy.

  1. Bleach disinfectant: This product demonstrated high efficacy in reducing THC concentrations in hair, showing an average reduction of 65%. However, the study does not provide specific details on the toxic nature of bleach disinfectant or its potential to damage hair and scalp.
  2. Shampoo with propylene glycol: was also highly effective in manipulating THC concentrations. It showed a mean reduction of 52% in THC levels after a single application. Importantly, the study highlights shampoo as safe for hair, without indicating any harmful effects on hair and scalp.

The study underlines the potential of these products to significantly alter drug test results based on hair samples.

It suggests that reliance solely on hair sample analysis for THC concentrations might be insufficient and recommends complementing it with other forms of drug testing, like urine analysis.

This is due to the observed ability of these products to manipulate THC levels effectively, which could lead to incorrect interpretations of an individual’s drug use habits.

Another study

Another study was done to see how a shampoo with propylene glycol affects drug tests on hair. They used hair from 14 people who had used drugs. This hair was washed with the shampoo and then tested for drugs.

They found that even after using the shampoo, drugs were still in the hair. But, the amount of drugs did go down significantly.

For example, the amount of cocaine found in the hair went down by 5%, heroin decreased by 9%, morphine levels dropped by 26%, and THC (marijuana) went down by 36%.

Old Style Aloe Toxin Rid Shampoo study results

So, the study showed that washing your hair with this shampoo does reduce the amount of drugs in your hair, but it doesn’t completely remove them after single use.

Propylene glycol is a key ingredient in Toxin Rid Old Style Aloe Shampoo. This component plays a significant role in its effectiveness for passing drug tests.

However, it’s important to note from research that a single use may not completely remove all traces of substances.

The studies clearly indicate that multiple applications of the shampoo are necessary for optimal results.

This is crucial to understand for anyone considering using this product for a drug test.

Later in this article, I will guide you on how to determine the right amount of shampoo you’ll need.

This will depend on your specific situation, including the type of drug use and your hair type.

Later I’ll provide personalized instructions to maximize the effectiveness of the shampoo.

How does Old Style Aloe Toxin Rid Shampoo work?

Understanding how Old Style Aloe Toxin Rid Shampoo functions requires a basic knowledge of hair structure.

Hair is primarily made of a protein called keratin and has three main parts: the cuticle, cortex, and medulla.

Hair structure

Cuticle: This is the hair’s outermost layer, made of overlapping scales. It protects the inner layers and contributes to hair strength.

Cortex: The thickest layer, the cortex contains most of the hair’s pigment, giving it color. It’s rich in keratin, which provides elasticity and strength.

Medulla: The innermost layer, not present in all hair types. It’s a soft, thin core that varies depending on the hair type.

Drug incorporation into hair

When drugs are taken, they enter the bloodstream and are metabolized. These metabolites, along with the parent drug, can become part of the hair structure.

As hair grows from the follicle, exposed to the body’s internal environment, drugs and their metabolites in the blood can enter the follicle and become part of the new hair, mainly in the cortex.

Once in the hair shaft, these substances are essentially “locked” in as the hair grows. Since hair typically grows about 1 cm per month, the segment of hair showing drug use can be identified.

Removing drug metabolites with the shampoo

Old Style Aloe Toxin Rid Shampoo works by targeting these trapped metabolites. It contains chemicals that change the keratin structure in the hair, releasing the metabolites. Additionally, it has solubilizing agents that help dissolve these metabolites, making them easier to wash out.

Does hair type matter?

When it comes to removing drug metabolites from hair, not all hair types are equal.

Some characteristics can make the detox process more challenging. Let me explain how different hair types respond to detox shampoos like Old Style Aloe Toxin Rid.

Challenging hair types

  1. Thicker Hair: Thicker strands mean a larger cortex, the area where most drug metabolites are stored. This can make detoxification tougher.
  2. Dense Hair: More density provides greater surface area and volume for metabolites to cling to.
  3. Low Porosity Hair: This type of hair has tightly bound cuticles, making it less absorbent. This characteristic can hinder the shampoo’s penetration, making metabolite removal harder.
  4. Darker Hair: Darker hair, rich in melanin, tends to bind more strongly with drug metabolites. The high melanin content can make these compounds tougher to wash out.
  5. Less Treated/Damaged Hair: Interestingly, hair that is less treated or damaged might resist detox shampoos better. Intact cuticles in such hair make it less permeable, unlike bleached or chemically treated hair, which is more porous and thus more receptive to detox shampoos.
  6. Older Hair: Hair further from the scalp, being older, has been exposed to the environment longer. This can lead to a more compacted structure, posing additional challenges in metabolite removal.

Is Old Style Aloe Toxin Rid Shampoo effective for all types of drugs?

A study, which you can find on ResearchGate, provides insightful data on this topic. Here’s a brief overview:

  • THC (Marijuana): The shampoo shows a significant reduction in THC levels, with a decrease of about 36% per use.
  • Morphine: It’s also quite effective against morphine, showing a reduction of around 26% per use.

However, the effectiveness varies with other substances:

  • Heroin: There’s a reduction of about 9% per use.
  • Cocaine: The decrease is around 5% per use.

How does Old Style Aloe Toxin Rid Shampoo сompare to home remedies?

When considering methods to pass a hair drug test, it’s important to weigh the effectiveness against potential risks. Let’s compare Old Style Aloe Toxin Rid Shampoo with popular home remedies.


Home remedies like the Macujo or Jerry G methods, often discussed on platforms like Reddit, can be more effective and faster.

They require less time to lower drug metabolite concentrations below detectable levels. However, these methods often involve harsh ingredients like bleach and vinegar, which can be more effective in flushing out THC, as shown in this study: NCBI Study on Bleach Effectiveness.

While they can expedite the process, there are significant downsides.

Hair and scalp damage

The aggressive nature of ingredients like vinegar and bleach can severely damage hair and scalp. They can cause burns, itching, and long-term damage.

Many people report drastic negative impacts on their hair health.

Here are some reviews from people that used home Macujo and other similar methods:

  • “Wouldn’t wish that process on my worst enemy.”
  • “The relaxer really irritates your scalp after the Macujo.”
  • “Bleach makes scalp burn like hell, apparently, and cause hair/scalp damage.”
  • “Crazy scalp melting treatment.”
  • “So when I damaged my hair, I felt like my life was RUINED.”
  • “After my test, I decided to cut my hair because I wasn’t trynna look like Patchy the Pirate, so I got a bald fade.”
  • “I had dandruff and pieces of my scalp were falling out for like a week and a half after.”

Additionally, a drug test collector can easily notice such damage, which may be interpreted as an attempt to cheat the test.

This could lead to hair being taken from other body parts for testing.


While the ingredients for home remedies might be cheaper and readily available, the cost of potential hair and scalp damage should be considered.

The expenses for restoring hair health and healing the scalp can be substantial. Moreover, if the outcome of the drug test is crucial, opting for a cheaper solution might not be worth the risk. Visible scalp damage could lead to alternative testing methods and potential legal consequences.


Tampering with or attempting to cheat on a drug test, especially in legally sensitive situations like court-ordered or probation tests, can have serious legal repercussions.

Methods that cause obvious hair and scalp damage can be easily detected by a drug test collector, leading to legal consequences.

In contrast, Old Style Aloe Toxin Rid Shampoo is a safer and legal alternative. It doesn’t damage the hair or scalp, and its ingredients are not detectable in a hair drug test, making it a legally compliant option.

Safety and side effects of Old Style Aloe Toxin Rid Shampoo

When it comes to the safety of Old Style Aloe Toxin Rid Shampoo, I can assure you it’s generally safe for use. It typically doesn’t cause side effects.

However, if you have a specific hair condition or allergies, it’s always wise to consult your doctor. Let’s take a closer look at its ingredients.

Old Style Aloe Toxin Rid shampoo ingredients

The shampoo contains a variety of components, each serving a purpose in the detox process:

  1. Aloe Vera: Renowned for its soothing and moisturizing effects, making it a staple in hair care.
  2. Propylene Glycol: Aids in ingredient penetration into the hair shaft.
  3. Tocopheryl Acetate (Vitamin E): Used for its conditioning properties.
  4. Avocado Oil: Nutrient-rich and known for moisturizing benefits.
  5. Soybean Oil: Often included for its conditioning and smoothing effects.
  6. Cocamide DEA: Derived from coconut oil, it acts as a foaming and emulsifying agent.
  7. Cocamidopropyl Betaine: Another foaming agent that assists in cleaning.
  8. Sodium Laureth Sulfate: A common detergent and surfactant.
  9. Sodium Lauryl Sulfate: Similar to Laureth Sulfate, known for effective cleansing.
  10. Other Additives: These may include fragrances, preservatives, and other ingredients for cleansing efficacy or product stability.

How to use Old Style Aloe Toxin Rid Shampoo

Using this shampoo can be a bit complex.

As I’ve mentioned earlier, a single use only reduces the concentration of drug metabolites in the hair.

Therefore, multiple applications are necessary to achieve the desired effect. The difficulty of cleansing can vary with different hair types.

hair types

The official instructions recommend 10-15 applications, but I’ll provide a more tailored approach.

I’ll focus on marijuana for this explanation, but the methodology for other drugs follows a similar pattern.

Let’s break down the usage frequency for different hair types in the upcoming sections.

How much Toxin Rid shampoo should I use?

Understanding how much Toxin Rid shampoo to use can be crucial for effective results.

I’ve done the math for you, considering various usage types and hair characteristics.

Below, you’ll find detailed tables indicating the required amount of shampoo for your specific situation, along with an explanation of our calculations.

hair length and how much detox shampoo is required

For light users

If you fall into the category of light users – those who indulge in marijuana once a week or less – your shampoo application needs are relatively moderate.

I recommend applying the shampoo at least 8 times to ensure thorough cleansing.

Hair type / Hair lengthShort (up to 15cm)Medium (15-30cm)Long (30+cm)
Light hair40 ml80 ml120 ml
Dark hair50 ml100 ml150 ml
Dreads60 ml120 ml170 ml

For medium users

Medium users, typically engaging in marijuana use 2-4 times a week, will require a more intensive approach.

If this describes your usage, aim for at least 14 applications of the shampoo to achieve the desired detoxification.

Hair type / Hair lengthShort (up to 15cm)Medium (15-30cm)Long (30+cm)
Light hair70 ml140 ml210 ml
Dark hair84 ml168 ml252 ml
Dreads98 ml196 ml294 ml

For heavy users

Those who use marijuana daily are considered heavy users. In such cases, the hair has been exposed to a higher concentration of metabolites over time.

Therefore, I advise a minimum of 16 shampoo applications for effective cleansing.

Hair type / Hair lengthShort (up to 15cm)Medium (15-30cm)Long (30+cm)
Light hair80 ml160 ml240 ml
Dark hair96 ml192 ml288 ml
Dreads112 ml224 ml336 ml

One bottle holds about 240ml of shampoo, which should be good for around 48 washes if you have short hair, 24 washes for medium-length hair, or 16 washes if your hair is long.

Understanding the calculation process

To ensure clarity and transparency, I’ll explain how we determined the number of shampoo applications needed to effectively reduce drug metabolite concentrations in hair. This calculation is crucial for anyone aiming to pass a hair drug test.

We employed the concept of exponential decay, which is quite fitting in this context. The formula we used is:

Final concentration = Initial concentration × (1−Decay rate) ^ Number of uses

Hair drug test cutoff levels for marijuana

For marijuana, the standard cutoff levels in hair drug tests are:

  1. 1.0 pg/mg for initial screening.
  2. 0.1 pg/mg for the confirmation test.

Basis of initial concentration estimates

To estimate the initial concentration of THC metabolites in hair, we referred to a comprehensive study available here: NCBI Research. This research provides an analysis of THC concentrations in hair for both light and heavy marijuana users. The findings indicate initial concentrations ranging from 3.4 to over 100 pg THC/mg and 0.10 to 7.3 pg THCCOOH/mg of hair.

In our calculations, we opted for the worst-case scenarios. This approach ensures that the calculated amount of shampoo will be more than sufficient to pass a drug test. It’s always better to have some shampoo leftover than to risk failing the test.

By following these calculations, based on scientific data from research, you can be confident that using the calculated amount of Toxin Rid shampoo will effectively reduce THC metabolite concentrations in your hair to pass the drug test.

Step-by-step guide to using Toxin Rid shampoo

  1. Begin using the shampoo daily, starting 3-10 days before your test.
  2. If time is limited, consider multiple washes per day as necessary
  3. During each wash, apply the shampoo and let it lather in your hair for 10 to 15 minutes.
  4. Ensure you use the shampoo the recommended number of times before your test.

Recommended shampooing regimen

  1. Start with your regular shampoo and rinse thoroughly.
  2. Apply a dime-sized amount of Old Style Aloe Toxin Rid Shampoo, focusing on soaking your hair.
  3. Finish with your regular conditioner.

Concentrate on the scalp area, as this is where toxins predominantly accumulate.

Aim to remove older layers of oil for a thorough cleanse.

By following these steps, you can confidently use Toxin Rid Shampoo to prepare for your hair drug test, ensuring the best possible outcome.
