Kristin Ess Shampoo Review: High Quality at Low Prices?


| |
| |

Kristin Ess is a popular hair care brand that has great packaging and reasonable prices. The brand claims that their shampoo gets hair “super clean” but also “leaves it feeling moisturized and looking shiny.”

But does Kristin Ess shampoo actually contain ingredients shown in research studies to have these effects? Does it contain any potentially harmful ingredients? How do real users rate and describe the effects of Kristin Ess shampoo? And which retailer sells this brand for the best price?

In this article we’ll answer all of these questions and more, as we analyze the ingredients in two of Kristin Ess' most popular shampoo products (Signature Shampoo and Purple Shampoo) based on clinical studies to give our take on whether or not these products are likely to be effective for improving hair quality.

We’ll feature unsponsored user reviews of the brand, and provide a cost comparison to show which retailer sells Kristin Ess shampoo for the best price.

Kristin Ess Signature Shampoo Review

Kristin Ess Signature Shampoo ingredients

The ingredients in Kristin Ess Signature Shampoo (which is one of the brand's best-sellers) are shown above.

Glycerin was shown in a medical review published in the British Journal of Dermatology to improve skin barrier function, hydrate the skin and have an antimicrobial effect, making it an excellent conditioning ingredient.

Chitosan is a natural anti-fungal ingredient derived from the shells of crustacean animals like crabs.

This ingredient was shown in a 2020 medical review to reduce levels of pathogenic bacteria on the scalp, making it a healthier option than commercial antifungals in our opinion.

This shampoo also contains some ingredients that may be questionable from a health perspective.

Fragrance is a broad categorical descriptor that could refer to any number of chemical compounds.

A 2016 medical review described the potential for “serious risks” to human health from fragranced consumer products.

Kristin Ess does offer a fragrance-free version, so we’d recommend consumers intent on purchasing from the brand choose that option.

Phenoxyethanol is a synthetic preservative found in at least one clinical trial to be toxic to human cells, as we documented in our Function of Beauty review article.

Sodium benzoate is another synthetic preservative.

Overall, we believe that Kristin Ess Signature Shampoo has the potential to improve hair moisture and quality, but we don’t currently recommend this product due to the inactive ingredients highlighted above.

Kristin Ess Purple Shampoo Review

Kristin Ess Purple Shampoo ingredients

The ingredients in Kristin Ess Purple Shampoo are shown above.

Basic Violet 1, which is an artificial dye, is used for the color.

A medical review published in the International Journal of Toxicology analyzed data on Basic Violet 1 and concluded the following:

“The panel concluded that because of the carcinogenic potential of these dyes, insufficient data exist to support the safety of Basic Violet 1, 3, and 4 in cosmetic formulation.”

Carcinogenic potential refers to the potential for an ingredient to cause cancer.

Fragrance is included, and we discussed in the previous ingredient analysis section why we consider this ingredient to be questionable from a health perspective.

Methylisothiazolinone is a synthetic preservative which is banned or prohibited by Health Canada due to safety concerns.

Overall, we do not currently recommend Kristin Ess Purple Shampoo due to these inactive ingredients, and we consider this formulation to be inferior to the Signature Shampoo formulation from a health perspective.

The top negative review from a verified purchaser is written by a user named “Amanda” who gives the product a 1/5 star rating, who dislikes the product experience and suggests it caused hair shedding:

"... the shampoo is horrendously drying and causes a lot of excess hair fallout, like, A LOT, and the conditioner, no matter how well you wash it out, leaves a waxy finish."

Kristin Ess Signature Shampoo currently has an average review rating of 3.8 out of 5 stars on Google.

Our Clean Hair Care Picks

Ingreendients Daily Shampoo is our top shampoo pick, because it's formulated 100% from plants and contains research-backed active ingredients like acetic acid, derived from apple cider vinegar (ACV), which researchers suggest "can condition hair making it softer, silkier, shinier."

Happy Head Topical is our top hair growth solution.

This formulation uses FDA-approved hair loss ingredients like minoxidil which is clinically shown to increase hair count by 11%.

The brand also publishes the percentage concentration of each active ingredient, which is a sign of quality and transparency.

Conclusion

Both of the Kristin Ess shampoos that we analyzed in this article (Signature Shampoo and Purple Shampoo) contained some research-backed active ingredients that may support hair quality.

However, both shampoos also contained several inactive ingredients that we consider to be questionable from a health perspective.

Purple Shampoo in particular contains both artificial dye and a synthetic preservative with restricted use provisions in Canada.

Kristin Ess offers fragrance-free versions of some of their products, and for consumers planning on purchasing from the brand, we would recommend purchasing those versions.

Most of the online customer reviews of Kristin Ess that we came across while researching this article were positive, and we'll give the brand credit that their packaging is excellent.

Amazon has the best prices on Kristin Ess shampoo at the time of updating this article, when factoring in shipping fees.
