How I Tested And Reviewed The Ouai and Kerastase Shampoos

Here are the parameters I chose while testing and reviewing these shampoos:

Ability to cleanse the hair:

This parameter rates and reviews how powerfully these shampoos can cleanse the scalp of dirt, buildup, grease and grime.

Scalp and hair gentleness:

While the Kerastase shampoo contains sulfates, the Ouai shampoo contains none. So I kept this aspect in mind while reviewing these products to see how gentle these shampoos felt on my sensitive scalp and hair.

Product effectiveness:

Both these shampoos have promising benefits in terms of dryness and frizz reduction. So this parameter will review to what extent this product benefits worked or not.

Fragrance:

I prefer using shampoos that have a mild scent, because harsh smells feel very overpowering when my hair dries. So this is an aspect I always keep in mind.

Price:

My ideal price range for a shampoo would be between $10 to $15. While both these shampoos were above my budget, I tested to see whether they were worth the price I paid or not.

My Kerastase Nutritive Shampoo Review

This was my very first try at the brand Kerastase and I found that the product has strong cleansing power. It did make my scalp and hair feel less greasy and fresh once it was washed and dried.

It definitely made my dry hair much softer over time and a few weeks into using this shampoo, my hair started feeling more moisturized as well.

The top ingredients in this shampoo are Glucose, Lipids & Iris Rhizome Extract that basically have 2 functions – a) they add hydration to your hair and b) the prolong this hydration to make hair appear fuller, smoother and healthier.

The lipids in the formulation can also help repair damage hair strands and accelerate new hair cell growth. So this is a fantastic choice if you have brittle, damaged hair.

Kerastase Nutritive Shampoo review

It has a pleasant smell, of what, I couldn’t tell. But it did make my hair smell nice once it dried.

In terms of the pricing, I felt like this product was overpriced and could have been a little cheaper, so this is one of the reasons I wouldn’t buy it again.

Another reason would be that this shampoo contains sulfates (but no parabens). So even though it didn’t feel harsh on my scalp and hair, the ingredient in itself isn’t a recommended one for hair health.

Kerastase Nutritive Shampoo

Ouai Thick Shampoo Review

I had tried the brand Ouai before when I bought their Detox Shampoo and I really liked that product, so I was quite certain that this product wouldn’t disappoint me. Well, it definitely didn’t!

Ouai Thick Shampoo

Comparing this shampoo to the Kerastase shampoo, I felt like this shampoo reduced my hair dryness and made my hair feel moisturized, softer and smoother pretty quick.

It took just a few washes, to reap the benefits.  I also liked the ingredients of this shampoo better than those used in the Kerastase shampoo.  

Since it is targeted at getting rid of dryness, the ingredients of the Ouai shampoo were more powerful in my opinion.

Ouai Thick Shampoo Review

Coming to the fragrance, I really liked how nice shampoo felt and it kept my hair smelling fresh for days.

This shampoo also has a good cleansing power (which the Kerastase shampoo also had). It helped cleanse my hair and scalp of buildup, dirt, grease and grime as well.

Talking about the pricing, this shampoo is super pricey! Even though I loved it and it totally fulfilled its promised benefits, the price was way over my budget.

Pros and Cons of the Ouai Thick Shampoo

Pros:

·         Contains no sulfates or parabens and thereby feels super gentle on the hair and scalp.

·         Has a lovely fragrance that makes the hair smell good and feels fresh once it dries.

·         Helps improve hair health and reduces hair dryness considerably within just a few washes.

·         Makes the hair feel smooth and soft over time.

Cons:

·         This shampoo is royally overpriced (even though it delivers good results).

Conclusion – Kerastase Vs Ouai Shampoos

Even though the Kerastase shampoo is priced lesser, I would pick the Ouai shampoo if I had to buy one again. It felt gentler on my hair and overall, when my hair dried, I preferred the smell of the Ouai shampoo.

Also, the Ouai Thick Shampoo contains no sulfates while the Kerastase shampoo does have sulfates (but no parabens). So there again, my pick would be the Ouai shampoo. But either way both these shampoos have a very powerful cleansing power.

If I had to choose one to reduce my hair dryness, even though both were pretty good, I’d pick the Ouai shampoo because of its better and more powerful moisturizing ingredients.
