Zydot Ultra Clean Shampoo Review

Hair drug tests are becoming more common, so many different companies are now offering hair detox-related products. However, most of these “detox shampoos” only wash your money down the drain. In this Zydot Ultra Clean shampoo review, we’ll analyze one of the most popular brands of hair test shampoo to find out whether it’s worth your attention.

What Are Zydot Products?

First, to provide some background on the company, Zydot is one of the oldest manufacturers of detox products for drug test dating back to 1987. Notably, they produce:

Ultimate Blend
This detox drink isn’t well-known probably due to the fact that it doesn’t contain any detoxifying ingredients. The only thing Ultimate Blend can do is improve your digestion a bit.
Euro Blend
The export version of Zydot detox drink contains the same ingredients apart from vitamin B8, so it’s not useful for drug test either.
Zydot’s Rapid Body Cleansing capsules are basically a pill version of Ultimate Blend, so they can’t aid toxin removal process in your body.
Ultra Clean
This 3-in-1 hair detox shampoo is the most popular product from Zydot, with many reviews stating it worked for a hair test. Ultra Clean shampoo & conditioner is marketed as a product which not only cleans residue of styling products like hair spray, but can also open hair shaft and remove oil buildup along with drug toxins.

Zydot Ultra Clean Shampoo

According to the manufacturer, Zydot shampoo and conditioner contain ingredients like Propylene Glycol and Aloe Vera, which are supposed to clean out weed metabolites from your scalp and hair follicles. The product comes in three separate packets, each with a set of instructions:

Zydot Shampoo (Step 1)

  • Wash your hair with your regular, everyday shampoo and rinse completely.
  • Apply ½ of Ultra Clean shampoo on thoroughly wet hair.
  • Massage the shampoo into scalp and hair, work up the lather, and leave it on for 10 minutes.
  • Thoroughly rinse using lukewarm water.

Zydot Purifier (Step 2)

  • Apply the entire purifier packet on your hair, massaging it thoroughly into the scalp.
  • Comb through the hair using a new comb or brush.
  • Leave the purifier on for 10 minutes.
  • Rinse well with lukewarm water.

Zydot Shampoo (Step 3)

  • Apply the remaining ½ of Zydot hair shampoo.
  • Massage it thoroughly into the scalp and hair, working up the lather for 10 minutes.
  • Rinse thoroughly.

Zydot Conditioner (Step 4)

  • Apply the entire packet of conditioner, massaging it into your hair and scalp.
  • Distribute evenly by combing through the hair.
  • Leave the conditioner in your hair for three minutes.
  • Rinse well.

This entire hair cleansing process takes about 45 minutes to complete, and Zydot provides additional directions for using Ultra Clean shampoo and conditioner to pass hair follicle drug test:

  • Avoid toxins (including second-hand smoke) for at least 24-48 hours before using Zydot Ultra Clean shampoo.
  • Use a new hair comb or brush after Ultra Clean shampoo treatment to avoid re-contamination.
  • Avoid contact with hats, hoodies, eyeglasses, pillows, car headrests, etc. for the same reason.
  • Zydot Ultra Clean is only effective for up 24 hours, after which contaminated sebum will re-enter hair shaft.
For individuals with higher toxin levels, hair longer than 6 inches, or thicker hair, Zydot recommends two or more treatments with Ultra Clean shampoo & conditioner.

Does Zydot Work for Hair Drug Tests?

Ultra Clean shampoo is advertised as a complete hair cleansing solution for drug tests. However, drug toxins are notoriously hard to expel from hair follicles, especially THC-COOH. Scientific studies show that Ultra Clean shampoo can remove only up to 36% of drug toxins1 from the hair, so it’s not as effective on its own as product info states.

As expected, Zydot Ultra Clean shampoo has mixed reviews, and those who say they’ve passed their hair drug tests used this detox shampoo as part of hair cleansing routine in conjunction with other ingredients like apple cider vinegar and salicylic acid, such as this Reddit user:

For the hair test, you want to open the hair cuticle, clean the inside of it, and close it back. I read conflicting information that an acid will open the hair follicle and a base will close it, and vice versa. So I did both. Did I overdo it? Possibly. Does it matter since I tested negative? Nah.StonerScientist84, Reddit

Here’s summary of information we’ve collected from different sources:

Light users
Occasional smoker should use Zydot Ultra Clean shampoo & conditioner as part of the Jerry G method. It’s a multi-step hair cleansing process which we’ll cover later in this review.
Medium users
Regular smoker (2-3 times per week) should use Zydot Ultra Clean shampoo together with Old Style Aloe Toxin Rid, since just one of them might not be enough for complete hair cleansing.
Heavy users
For chronic smokers, Zydot Ultra Clean works best when paired with Old Style Aloe Toxin Rid shampoo, both used as part of the Macujo method. Like Jerry G, it employs several different items to achieve complete hair purification.

Jerry G Method Review

Jerry G is a multi-step way of cleansing designed to open hair cuticle and allow products like Zydot Ultra Clean shampoo to remove impurities. In comparison to Macujo, Jerry G uses more harsh chemicals, so it’s employed mainly by people who can’t afford the cost of Aloe Rid shampoo. Jerry G requires the following ingredients:

  • Sodium bicarbonate (baking soda)
  • Hydrogen peroxide (hair bleach)
  • Hair dye (one that contains ammonia)
  • Old Style Aloe Toxin Rid (optional for light users)
  • Zydot Ultra Clean shampoo & conditioner
  • A new towel and hair comb or brush

Ammonia is necessary to open up hair cuticles and allow other products to “work their magic”. However, it can damage the eyes, which is why we advise extreme caution. The steps of Jerry G method include:

At least 10 days before hair follicle test, stop using marijuana and other drugs. If time allows it, it’s best to repeat hair cleansing process (steps 2-3) again after 10 days while still abstaining.
Bleach your hair, and then dye it back to your natural hair color, so it doesn’t cause suspicion. Make sure to use permanent dye with ammonia. Don’t blow dry your hair as this can cause additional damage.
Next, wash your hair using Aloe Rid shampoo according to the manufacturer’s instructions. Light users can instead use an extra pack of Zydot Ultra Clean or ½ of Rescue Detox shampoo bottle.
Repeat steps 2-3 on the day before your hair testing. Ideally, you should wait 10 days after the first cycle, but you can do this immediately, though this can be more damaging to your hair.
On the day of hair test, prepare baking soda paste by mixing it with some water, then massage it into your hair and scalp.
Rinse out the paste, and wash your hair with Aloe Toxin Rid (or remaining ½ of Rescue Detox shampoo) once again.
The final step is to wash your hair and scalp using Zydot Ultra Clean shampoo & conditioner. Its effectiveness can be increased if you have a shorter haircut at this point.

Where To Buy Zydot Ultra Clean Near Me?

Zydot Ultra Clean is an old and popular product, so it’s available at certain large stores:

  • Available at Walmart.com (only online)
  • Available on Amazon and eBay
  • Not available in Walgreens
  • Available on TestClear.com with overnight shipping
Beware of the fakes on marketplaces above; they’re known for selling knock-off Nexxus Aloe Rid, so there’s no guarantee that Ultra Clean is genuine either, especially if the price is very low. TestClear is the official supplier of Ultra Clean and Aloe Rid (and the only one of the latter), and they’ve been on the market for years, offering flexible shipping options.


To summarize our Zydot Ultra Clean shampoo review, it does a good job when used as part of Jerry G method, and has exceptionally high success rate as a combo with Aloe Rid shampoo, since their ingredients complement each other well. Make sure to avoid knock-offs and cheap detox shampoos claiming they can cleanse your hair for drug test with no additional items.
