My Review

This shampoo took a little longer for me to start seeing results. However, the hair was bouncing and shiny, so I liked it.

Best shampoo and conditioner for keratin treated hair

I have noticed a significant reduction of frizz, even though not entirely, but the effects were there. So in this quest, I can say I was pretty happy.

As I have voluminous hair, I noticed it got even more voluminous. It’s alright, though, as I still liked how it looked.

Another thing that I liked about this shampoo is how it makes it easy to untangle the hair. 

As I felt my hair soft, I can start untangling with the fingers in the shower and then with a comb.

I tried this shampoo with and without conditioner and a hair treatment mask, and the results got even better, as I expected.

The way I used it is the following:

I gently massage the scalp, and instead of circular motion, I move my fingers back and forth. Then I wait around 3 minutes and rinse again.

As I have too dried hair,  I prefer to use a conditioner and hair treatment mask after I wash my hair, as I feel that this helps improve my hair condition.

But Don’t Stop with my review; check out what people are talking about this Shampoo For Keratin Treated Hair and decide for yourself, based on thousands of other opinions.

My review

ArtNaturals Organic Moroccan Argan Oil Shampoo and Conditioner Set - Sulfate Free - Infused with Keratin

After using this shampoo for two months, I noticed my hair gradually improved, but it was not overnight. 

The progress starts to build up slowly, so it’s good to stick with the treatment and be patient, so you can begin to see plausible results.

I had also noticed improvements when I applied olive oil to my hair 2 to 8  hours before washing. 

This trick works well with any shampoo.

The situation of my hair:

My hair is dry. I am styling it with a flat iron most of the time because of volume and frizz. 

This shampoo didn’t eliminate all my frizz and volume, but it was ok. 

That shampoo tamed around 60% of my frizz, and I noticed my hair was softer. 

In addition to the oil tip I gave you, there are some other things you can do to maximize results.

One tip is to use a conditioner. Almost 99% of the time, I have a better and more optimized result when I do it. 

Try to use a proper conditioner for very dry hair. I like one from Biolage Oil Mitic, which my mom and I love!

The other tip is to have a dedicated hair mask for your hair type; 99% of the time, a high-quality masque can make your hair much softer.

I am very in love with the Keune keratin treatment mask and have been using this one for a month now—nothing to complain about, just goodies.

The way I wash

I dilute the shampoo with a bit of water. I always do that because I feel it is less abrasive.

This shampoo won’t lather too much, so don’t worry, it’s still doing its job.

I gently massage the scalp, and instead of circular motion, I move my fingers back and forth. Then I wait around 3 minutes and rinse again.

As I have too dried hair,  I prefer to use a conditioner and hair treatment mask after I wash my hair, as I feel that this helps improve my hair condition.

The cons

The cons about this shampoo are that it took a while for me to start seeing the results. But the result is good, so far.

4. HASK KERATIN PROTEIN Shampoo and Conditioner Set 

Our next Best shampoo for keratin treatment contains argan oil and is excellent, in my opinion (and has thousands of great reviews out there).

This shampoo might be ideal for damaged, over-processed hair, and some people call it a “miracle” that restores and strengthens parched frizzy hair, especially curly hair.

5. Pantene Sulfate Free Shampoo & Conditioner Kit 

Here we have apremium shampoo that you can use on keratin treated hair or any other hair that needs an extra touch of care.

This version is sulfate-free, so you can expect it won’t ruin your keratin treatment. For better results, you can use the conditioner of the same line.


The Pantene sulfate-free shampoo contains Pro-V nutrient combined with rose extract is gentle and leaves the hair softer and smoother.

If combined with its conditioner (also sulfate-free), you’ll notice hair gets more malleable, easier to detangle, and hydrated.

This Pantene shampoo is sulfate-free, paraben-free; there are no dyes in the composition, no mineral oils, and is silicone-free.


Some people have complained about the package. To be more specific, people have complained about the pump, but they love the smell.


In a nutshell, here’s what to expect from Pantene rose water:

  • Great smell and stays on the hair for 2 or 3 days
  • Soft, hydrated hair
  • Gentle nourishment 
  • Makes detangling easier
  • To have potentialized results, use the conditioner with the shampoo kit.
  • sulfate free shampoo
  • Don’t strip hair natural oils

6. Free & Clear Hair Shampoo Fragrance

I like the concept of the Free & Clear Hair Shampoo. 

It is Fragrance-free, Gluten-free, and sulfate free shampoo, designed especially for Sensitive Skin, which you can use in keratin treated hair.

I know this is the least important thing, but I also like the bottle a lot, as It reminds me of a clean natural product. 

This shampoo is for those who want to get something natural, exceptionally gently after ​​keratin treatments.

In the case you have a sensitive scalp, you will love it. 

As you will see on the package, it clearly states that this shampoo is free from dyes, has no fragrance, no masking fragrance, it’s PH balanced and dermatologically tested.

Here’s the complete list

  • Sulfate-free
  • Dye Free, fragrance-free, masking fragrance-free lanolin-free, paraben-free, formaldehyde-free, and other preservatives that can irritate. 
  • Phosphate-free
  • Protein-Free
  • Gluten-free
  • Don’t strip hair natural oils

This shampoo can be used on all hair types, but especially for those with sensitive scalp and dry hair because its formula contains oil control agents. 

The hair will get clean and easy to detangle, and you can experience it becoming shinier. However, it is not a nourishing shampoo.

It will work great on keratin-treated hair because it has no harsh ingredients and will help you maintain your treatment, but it washes.

For the cons, many people have reported that this shampoo is difficult to spread, making you have to use a lot of product until you feel your hair is clean.

For this reason, you will need (in most cases), to use this shampoo in conjunction with a conditioner, deep conditioner, and/or a very moisturizing hair mask. 

Knowing this, use this product if your hair and scalp tend to get very oily, itchy, or irritated because it will nourish your scalp but will leave your hair dry if you have chemically treated hair.

7. Redken Color Extend Magnetics Shampoo

Now I bring an option for those with color treated hair (we cannot forget about you!). 

The Redken Color Extend Magnetics Shampoo can also be an excellent option for you after performing a keratin treatment blowout.

I am saying this because it is sulfate-free, non-stripping, and lightweight shampoo, which helps seal the color while leaving it smooth, nourished, and strong.

Like any other shampoo, the results will be potentialized by the sulfate-free hair mask from the same line. 

It’s suitable for all hair types, but use it only if you dye your hair frequently to enhance shine, prevent color from fading, and maintain color treated hair shinier for longer.

Tips For Washing keratin treated hair

After keratin treatment, it is best to avoid deep cleansing shampoos (anti-residual) as they can strip off the treatment.

At the same time, don’t forget to deep condition and hair masques once a week to avoid damage from keratin treatments.

Hydrate your hair with moisturizing hair creams, and avoid bleaching in short intervals as it can cause breakage and other damages.

If the hair is already damaged, use restorative, reconstructive hair masques and don’t do another Keratin treatment until the hair recovers. Another tip is to avoid sleeping with wet hair as it changes the hair structure.

Tips To Take Care Of Keratin Hair

If you want to take good care of your keratin treated hair, it’s a great idea to invest in a shower filter. This is actually good advice for every one who wants to have better hair, as hard water can leave your hair dry and frizzy. 

Also, remember to avoid beach and swimming pool baths, to help your treatment to stay longer.

Another tip is not to wash your hair so often in the beginning and keep it dry for as long as you can. If you feel your hair is too oily, you can use a dry shampoo. 

When you wash your hair make sure to use a lot of conditioner, hydrate and deep condition regularly to your hair to get stronger and shinier. 

Never sleep with the hair wet and opt for a silk pillow to help you get rid of excess frizz.
