Olaplex vs OUAI: Which Shampoo/Conditioner Is Better?

Everyone loves to show their hair when it’s full, soft, smooth, bouncy, and shiny. But when it becomes messy, dirty, dry, and greasy, it becomes a thing of embarrassment for the owner.

If you’ve ever had your hair damaged as a result of bleaching, you know how degrading it can be. Fortunately, there are plenty of products that can reduce the chances of damaged hair due to coloring.

Olaplex is a popular one for this. Another choice that has been in the limelight is the OUAI fine shampoo. Both have their strengths and weaknesses, so in this article, I’ll be comparing them to be able to see which one is better.

Olaplex vs OUAI: Comparison & Review

Price

In terms of price, both products are pretty close. Olaplex usually retails for around <30 dollars depending on where you’re buying from. The OUAI shampoo price is similar too.

In most cases though, you may likely be spending more when you choose Olaplex. Aside from being cheaper, the OUAI shampoo comes in a slightly bigger bottle than the Olaplex.

Packaging

Why it’s not important, the packaging of both products is another thing worth looking at. The reason I said that is because you’re mostly concerned with what’s inside the container and its effectiveness.

Anyway, given a choice, I’ll go with the OUAI because of its sleek and modern look. Olaplex has maintained the same classic look in all of their shampoos so that even the latest Olaplex product looks exactly like the first one.

You can’t blame them though as long as their product works, they can’t care too much about the looks.

If you go with the Olaplex No.4 or No.5 shampoo, you’ll get a bottle of 250ml (8.5ounce) against the 300ml (10ounce) of the OUAI. This is obvious. It will take you a long time to exhaust the OUAI than Olaplex.

If you value every drop of the liquid (why not, you paid for it), you’ll likely want to go for the OUAI. But before you decide, let’s look at other aspects.

Texture

Another thing to consider is that the Olaplex shampoo/conditioner has a creamy texture as against OUAI, which is thinner. This means you’ll go through the OUAI shampoo quicker than Olaplex so that you’ll need to replace it faster.

Olaplex vs OUAI: Reviews 

Now, on to what the products promise to do.

OUAI Shampoo

OUAI Fine Shampoo

If you look at the back of the OUAI shampoo/conditioner, you’ll see that it says it’s a fine shampoo that can bring life into your hair and strengthen the strands, thanks to the keratin and biotin content.

The product actually lists a couple of good ingredients like chia seed oil, keratin, biotin, nourishing hemp extract, etc. The formula is meant to add volume to your hair and leave it feeling bouncy and full.

Biotin is used to treat hair loss. Research has suggested that when the hair takes it in, biotin can improve thinning hair and assist in hair regrowth.

Keratin is usually absorbed by the hair cuticle and will make your hair look full and glossy. Chia seed oil is good for hair growth as it’s filled with fiber, protein, calcium, omega-3 fatty acids that can help in making your hair stronger, smoother, and more hydrated.

Hemp extract does something similar, working mostly on the scalp to promote hair growth. These are some of the explanations of some of the important ingredients in the OUAI shampoo.

Olaplex Shampoo/Conditioner

Olaplex No.4 & No.5

As you probably know, Olaplex is a concentrated shampoo for professional use which contains bis-aminopropyl diglycol dimaleate and phenoxyethanol which Olaplex says will restore, repair, and hydrate your hair.

According to Wikipedia, this ingredient usually forms ionic disulfide bonds in the hair, thus repairing any damage caused by bleach. At this point, it’s important to mention that Olaplex says this product is color-safe.

So, when you’re about to color your hair, it’s good to use it to keep your color and prevent damaging your hair bonds. And if you bleach your hair and experience some damage, Olaplex can be effective in restoring your hair to its original state.

The shampoo is also made without parabens, gluten, or sulfates and is vegan. The Olaplex Hair Perfector can work on all types of hair.

There is a professional version, which is used in the salons, as well as an after-service one that you take home for use to keep your hair color fresh and safe from fading away quickly. 

There are a couple of things to note here. First, there are not a lot of hair care products out there that are vegan.

It’s possible to argue that but when you consider the sheer number of products in this industry that are not vegan or cruelty-free, you’ll quickly realize that the percentage of those that are is indeed small.

I’ve researched quite a bit of hair care brands and it’s surprising how many brands struggle to be vegan or cruelty-free. So, if you like your products vegan or even sulfate-, paraben-, gluten-free, then Olaplex is a good option.

These ingredients (or chemicals, if you will) can damage your hair. As they build up in the hair, they weaken the hair strands and hold your hair from growing.

Another good thing about the shampoo is that it’s color-safe. Imagine spending a huge time preparing for coloring your hair, then spending a good amount to get it done, only for you to ruin it all with your shampoo.

Final Verdict on Olaplex vs OUAI

I’ve incorporated a number of differences between these shampoos/conditioners. When you go onto sites like Sephora/Amazon, you’re likely to see people posting reviews on these products. Some will batch Olaplex and others will praise it.

The same goes for OUAI’s product.

What you can gain from that is that people have different hair types, so these shampoos can result in varying results. If you’re going to use Olaplex, try and enlist the help of a salon that is experienced with Olaplex.

Many people go and use the product themselves without experience and then complain of losing so much hair. Only use the product when you’re sure and can follow instructions to the letter.
