Zydot Ultra Clean Shampoo Overview

Zydot Ultra Clean Shampoo comes contained in a slim blue box and includes three packets:  The Shampoo itself, the Purifier, and the Conditioner to use after. The instructions are also included, printed on a quarter sheet of paper.

The product is intended to be used after shampooing with regular shampoo to remove buildup and oils (do this twice if your hair is especially dirty). Then, half the Cleansing Shampoo is worked through the hair into a lather allowed to process for 10 minutes.  Next, you’ll apply the Purifier to the hair closest to the scalp (it won’t lather, so you’ll need to take care to distribute it evenly) and process for 10 minutes.  Then the shampoo step is repeated with the second half of the shampoo packet, followed by a deep conditioner to restore hair’s texture and manageability.


Zydot Ultra Clean Shampoo First-Hand Review


The Ultra Clean Shampoo itself smells a bit like baby shampoo, with a hint of cherry, or perhaps that ubiquitous pink liquid soap that’s in public restrooms.  It’s not unpleasant, but it’s not something we’d seek out for everyday use either.

The Purifier has a bit of that baby shampoo scent but with an edge of industrial soap or degreaser.  It’s a bit harsher, but it doesn’t leave a residual odor in the hair after rinsing.

The Conditioner component smells similar to the Ultra Clean Shampoo, with the prominent components being baby shampoo and something fruity. Again, it won’t leave much of a scent behind in your hair after rinsing.


The Zydot Ultra Clean Shampoo is transparent and viscous, making it easy to control when applying.  It lathers intensely, which gives us high hopes for its cleansing properties.

The Purifier is a clear gel that you work into your hair evenly.  It doesn’t lather, so you’ll need to be sure to apply it evenly to the hair closest to the scalp.  Fortunately, the thick consistency makes it very easy to handle — be careful to work it through all over without missing any spots.

The Conditioner is very creamy and thick in texture, with a light, pinky-peach tint to it.  It’s rich and opaque and blends easily into hair. Focus this on the roots of your hair, which is the part that experienced the brunt of the stripping properties of the Shampoo and Purifier.


The Ultra Clean Shampoo certainly feels intensely purifying.  It cleared our hair of all traces of oil, which is excellent for detoxifying purposes — but not so great for hair health or color-treated hair.  If you dye your hair, especially with a direct dye, you’ll likely need to recolor it after all this is over (our color-treated hair lightened by a full three levels by the time it was all said and done, and the water from rinsing the Zydot Ultra Clean Shampoo and Purifier was intensely colorful, indicating serious washout we don’t experience with regular shampooing).  If your hair is all-natural, the color won’t be affected, but it may feel dry or damaged by the end of the process. This can be remedied with a couple of deep-conditioning treatments and perhaps a product or two containing keratin to help add back strength over time.

The Purifier goes on fairly easily (take care to work it in evenly around your roots, especially at your crown — where you’re most likely to have a sample taken from).  Our hair felt seriously dry at the roots after this (remember not to concentrate the product farther down than three to four inches to minimize damage), but also very, very clean.  We let it process for 10 minutes, then rinsed another wash of color down the drain.

The lather of the second detox shampoo was as intensely colorful as the first, which wasn’t surprising but did leave us wondering how much color we’d be left with — we were focusing it on our roots only, not the lengths.  After 10 minutes of processing, we rinsed the technicolor suds down the drain and proceeded to the conditioning step.

The Conditioner is creamy and blends easily into the hair, making it very easy to apply.  We strongly recommend focusing on this conditioner where the Shampoo and Purifier have been, as they’ll need it the most.  Your regular conditioner or a different deep conditioner should be sufficient for your ends.

The aloe vera extract and hydrolyzed wheat protein in the Conditioner help add back strength and moisture — we were pleasantly surprised at how soft our hair felt after rinsing.  It did a good job restoring manageability, softness, and shine. That said, we’d say it restored our hair to about 70% of its original condition. Deep conditioning and protein treatments in the weeks following cleansing are essential to rebuilding hair health.  You might also need to recolor your hair, depending on the color you use and your hair type.

Zydot Ultra Clean Price & Comparison

At $35.95, this product is much more affordable than the alternative detoxifying shampoos.  It is considerably harsher, but it is effective and should work for light – to medium-frequency consumers.

This shampoo system provides a seriously deep clean, but if you want to make it part of an extended cleansing routine rather than a one-off clean, we recommend pairing it with the Aloe Toxin Rid shampoo.  You can use the Aloe Toxin Rid in the week leading up to your test, with final deep cleanse with Zydot the day of the test.  This is the best way to ensure a thorough clean if you’re a heavy cannabis consumer.

Product Quality

This product is intended to be used as an intensive final detox on the day of your hair follicle test.  It is not intended for repeated use, though you could conceivably use it at the start of a week-long cleansing regimen, then give your hair time to recover by deep-conditioning between gentler cleansing methods before using the Zydot Ultra Clean system a second time the day of your test.

We found our hair thoroughly, intensely clean after using this product, but it may strip the color out of hair that’s dyed.  You’ll have the best results if your hair is untreated.

There are tons of detox methods and products available, but we trust TestClear for products that provide consistent, clean results.  Zydot Ultra Clean Shampoo works reliably, which matters for something as critical as employment or legal status.

Frequently Asked Questions about Zydot Ultra Clean Shampoo

1. Does Zydot Ultra Clean work?

  • Kind of. Using Zydot Ultra Clean Shampoo on its own will not make you pass a hair follicle drug test. However, when it is used as part of a thorough detoxifying process, it will help. It may take a lot of time, so ensure to detoxify your hair before the day of the exam.

2. How long does the Ultra Clean shampoo last?

  • Zydot Ultra Clean Shampoo lasts up to 24 hours. The scalp and hair produce oils that will inevitably introduce contaminants to the hair. When using the detoxifying shampoo: avoid having the hair contact items such as pillows, eyeglasses, hats, headrests, and even hoodies. Thoroughly clean those items first before using them.

3. What is in the Zydot Ultra Clean Shampoo?

  • The Ultra Clean shampoo & conditioner contains aloe vera, a plant that naturally improves dry and damaged hair and is suitable for cleansing the scalp.
