How Olaplex & Ouai Work

Both Ouai and Olaplex use their own unique formulas to help take care of your hair.

Product Characteristics

Olaplex and Ouai both compete within the hair care market. They both have products such as shampoos, conditioners, leave-in conditioners, and oils. The most popular for both of the brands are their shampoos and conditioners.

Olaplex’s shampoos and conditioners are designed specifically for maintenance and repairs. This is because Olaplex has crafted its product line to be seen as a complete hair treatment and maintenance kit.

This includes products to be used before, during, and after the coloring process of your hair. These products are all designed with repair and restoration in mind. 

No More Tangling!

This is in contrast to Ouai as they do offer the same maintenance and repair benefits, but also nourishment and care, being a much thicker consistency because of it.

Both Ouai and Olaplex products are scented, with Olaplex being a sweet aromatic smell and Ouai being slightly less harsh on your hair.

Ouai has carefully chosen its chemicals and ingredients to treat your hair with the utmost care and delicacy so that nothing is too harsh.

Price Point & Product Quantities

Shocking Secret Exposed:

Both Olaplex and Ouai are professionally marketed products and occupy a very distinct part of the market. These are taunted as professional-grade, salon-quality products and command the price associated with that as well.

Olaplex has gained an exceptional reputation for its innovative approach to hair care. Its patented technology is known to repair and restore hair bonds, leaving hair stronger and more resilient after each use. This unique formula has made Olaplex a go-to choice for individuals looking to tackle hair damage and achieve salon-quality results at home.

Olaplex and Ouai are similarly priced but an important thing to note is that Ouai comes in slightly larger packages, for the same price. Due to Olaplex often coming in smaller quantities, Ouai is the more affordable option between the two.

Another distinction to make is that Ouai, in order to be more environmentally conscious, offers refill sachets of its products. These refills are great as they reduce waste, but they come with monetary benefits as well.

These refills are a little bit cheaper than purchasing another product entirely, thus making Ouai even more affordable than Olaplex.

Product Ranges & Variations

Versatile Hair Care by Ouai

Olaplex may be amazing in its use and technology, but it lacks the diversity and range of Ouai.

Ouai boasts a wide range of products for various hair types and conditions. It splits its products to be easily found by customers into products designed for fine hair, medium hair, and thick hair. This can be found throughout their range of shampoos and conditioners. 

Olaplex may be of generally superior quality, but they have taken a ‘one size fits all’ approach. Although this is great in theory, it does not always work. Customers can experience different levels of success due to this and often prefer something more catered to their exact needs.

Product Compatibility & Results

In the real world, we do not tend to buy all the products we use from a single place or from a single brand. The modern environment leaves us spoilt for choice and thus we find what we need from a variety of places.

This is an important part of choosing between these brands as what you use should never decrease the results that you have achieved elsewhere. 

Both Olaplex and Ouai state that they work well when used alongside other products. However, Olaplex is the brand that clearly wants you to use its entire kit for the best possible results.

Although this might not be your thing, it is well known that an Olaplex kit can deliver amazing results. 

Conversely, Ouai places a strong emphasis on product compatibility, allowing you the freedom to blend their products with your existing hair care routine. This approach caters to individuals who appreciate a personalized approach to their hair care. Ouai’s formulations are designed to harmonize with a wide range of other brands, making it effortless to integrate them into your daily regimen without compromising the overall effectiveness of your hair care routine.

Whether you lean towards the comprehensive system offered by Olaplex or the mix-and-match versatility of Ouai, both brands strive to deliver results that enhance and transform your hair. The choice ultimately comes down to your individual preferences and the specific needs of your hair care routine.

The clear choice for professionals within the beauty space is undoubtedly Olaplex. Although they may not be too diverse in their offerings, what they do, they do incredibly well.

They have designed their offering to compile into a complete hair care kit that strives to protect and prevent your hair from breakages as well as aid in repair, restoration, and maintenance.

Their shampoos and conditioners come in slightly smaller containers than Ouai so even though they are similarly priced, Olaplex is a slightly more expensive product. But, it’s a minor difference and it could be argued that it’s well worth it.
