Costco's Kirkland Signature Moisture Shampoo has sparked considerable debate, primarily focusing on its manufacturer and potential resemblance to other well-known shampoos. While opinions vary, its quality relative to its price is generally acknowledged. For years, it was widely believed to be a dupe for Pureology. This article will explore the shampoo's ingredients, performance, and value proposition, offering a comprehensive review for potential buyers.
Costco is known for its Kirkland Signature line, often partnering with high-quality, well-known suppliers for its manufacturing. This approach ensures that Kirkland Signature products meet a certain standard of quality while remaining competitively priced. This reputation is a major factor driving the popularity of Kirkland Signature Moisture Shampoo.
The consensus among many online reviewers was that the Kirkland Moisture Shampoo closely resembled Pureology Hydrate Shampoo, particularly in its look and scent. However, in 2021, Costco reformulated the Kirkland Signature Moisture shampoo and conditioner. The change was significant enough to alter the shampoo's characteristics. While it remains a solid, budget-friendly moisturizing option, the pre-2021 version was much closer to Pureology in terms of smell, look, and feel. Nowadays, the ingredients are far more similar to Olaplex.
A closer look at the ingredients reveals interesting similarities. Eight of the top ten ingredients in Kirkland Moisture Shampoo and Olaplex No. 4 are identical. This suggests that the Kirkland shampoo is comparable to salon-quality products.
To provide a more detailed evaluation, let's compare Kirkland Moisture Shampoo with Olaplex No. 4 across several key factors:

Directly from the bottle, the two shampoos have slightly different scents. However, when used in the shower, the scents become remarkably similar. The concentrated fragrance differs noticeably, but the basic scent qualities are comparable when dispersed.
The Kirkland Moisture Shampoo lathers marginally better than Olaplex No. 4. This could be due to the user subconsciously using more of the Kirkland product, given its larger bottle size and lower price point. Regardless, the difference in lather is not substantial.
Subjective testing reveals no discernible difference in performance between the two shampoos. Using each shampoo on different sections of hair and alternating between washes yields indistinguishable results.
Individual hair types can influence shampoo performance. The test hair is long, color-treated, fine, dry-ish, and somewhat unruly with a slight curl.
In 2020, Olaplex was acquired by a large private equity firm. Private equity firms are known for seeking ways to increase revenue. Shortly after the acquisition, Olaplex products became available online at Costco.com. While this doesn't definitively confirm that Olaplex is manufacturing the Kirkland Signature Moisture Shampoo for Costco, it suggests a potential relationship between the two brands.
