Ever wondered which is the best between Olaplex Clarifying Shampoo vs Ouai Detox Shampoo? Keep reading to find out the winner.
When it comes to clarifying shampoos, I don’t play around.
My hair is fine, gets oily fast, and easily weighed down by products so I needed something that deeply cleansed, but didn’t strip or flatten my hair.
We Ran An Experiment With Two Hair Types
So I decided to put the two most hyped clarifiers to the test: Olaplex Clarifying Shampoo vs Ouai Detox Shampoo.
To give a more well-rounded comparison, I asked my friend Amara, who has 3A curly hair that’s thick, bouncy, and often prone to product buildup at the roots.
We have previously compared ALL Olaplex vs Ouai products in the past, so we decided to put both shampoos to the test, over 2 weeks and we compared notes.
Here’s what happened.
Olaplex Clarifying Shampoo vs Ouai Detox Shampoo
What We Tested
- Olaplex No.4C Bond Maintenance Clarifying Shampoo
- Ouai Detox Shampoo (with Apple Cider Vinegar)
We both swapped our usual shampoo routine for these, using each one once per week with our regular conditioners afterward (I use a lightweight volume conditioner, Amara uses a deep moisture mask).
My Experience: Olaplex Clarifying Shampoo on Fine Hair
Olaplex’s No.4C has a creamy, almost lotion-like texture, not what I expected from a clarifier. It doesn’t foam much, but after rinsing, my scalp felt fresh and my hair had more natural shine and bounce.
What I loved about Olaplex Clarifying Shampoo:
- Didn’t dry out my ends
- My scalp felt detoxed without feeling tight
- Hair had a soft, touchable finish after blow-drying
What I didn’t love:
- Minimal lather (made it hard to tell if I’d used enough)
- Needed a little root boost styling spray to add volume
💬 My thoughts: “If you have fine hair like mine, Olaplex 4C gives a deep clean that doesn’t strip or flatten. It’s more subtle, but in a good way.”
Amara’s Take: Olaplex 4C on 3A Curly Hair
Amara found Olaplex gentle on her scalp but a bit drying on her curls. She said it cleared all the gel and curl cream residue from her roots, though her ends craved extra moisture afterward.
💬 Amara’s thoughts: “It worked wonders on my scalp, but my curls felt thirsty. I had to double up on my leave-in after.”
My Experience: Ouai Detox Shampoo on Fine Hair
The scent. Let’s start there. Ouai’s Detox Shampoo smells incredible, a luxe, clean, floral scent that lingers lightly even after your hair dries.
It lathered much more than Olaplex and gave me that satisfying squeaky-clean feeling at the roots. It instantly lifted grease and product residue, and my hair felt lighter than it had in weeks.
What I loved:
- Super foamy (easy to spread through roots)
- Boosted volume without needing mousse
- Hair stayed fresh for 2–3 days
What I didn’t love:
- Can be drying if used too often
- Scent might be overwhelming if you prefer fragrance-free
💬 My Thoughts: “Ouai Detox makes my hair feel like it just left a blow-dry bar. I reach for this when I need a reset.”
Amara’s Take: Ouai Detox on 3A Curls
Amara loved the deep clean and scent, but said it stripped a bit too much moisture from her curls. Now she uses it just once every 10 days with a heavy-duty mask afterward.
💬 Amara’s Thoughts: “The way my scalp felt afterwards? Amazing. But my curls needed extra TLC right after. Definitely not a daily-use product.”

Which One Is Best for You?
Use Olaplex 4C if:
- You have fine or color-treated hair
- Your scalp is sensitive to strong surfactants
- You want to maintain softness while clarifying
Use Ouai Detox if:
- You use a lot of dry shampoo or styling products
- You love foamy, fragrance-forward shampoos
- You want instant volume and a stronger cleanse
Personally, I now use Olaplex 4C every 2 weeks and Ouai Detox once a week especially after styling-heavy days. Amara does the same, but always follows with her favourite deep conditioner.

My Final Thoughts On Olaplex Vs Ouai Clarifying Shampoo
In the battle of Olaplex Clarifying Shampoo vs Ouai Detox Shampoo, there’s no single winner, just different strengths.
Olaplex is like your hair’s quiet overachiever: gentle, smart, and strengthening.
