Have you done a keratin treatment and you want it to last a while? If you want your hair to look shiny, silky and beautiful for a lot longer, you have to choose the right shampoo. The best shampoos for keratin treated hair are those without sulfates. Here, I’ll tell you what are the three best.


 I have my favorite. I’m not going to lie to you, but I wanted to give you three options so that you can choose that best that fits your needs. 


Finally I had done it.

I had gotten my hair to look perfect: no frizz, glowing, full of life, after getting a keratin treatment.


Before the keratin, I had horrible frizz.

Finally, I had done it.

The treatment erased the horrible frizz like it was magic.


Before, my hair looked sad and lifeless.

Keratin turned my hair shiny and glowing as if it had never been dyed. But there’s more.


Before the treatment, I took me a half hour every day to get my hair more or less presentable. Between washing, drying, and brushing, I lost half an hour every day.

After doing the keratin, in less than 10 minutes my hair looked splendid


I was in love with my new hair.

I wasn’t ashamed to take the classic weekend selfies.

Finally, I could show off my hair.


But everything good comes to an end.

 In a few short weeks, I went from complete fascination for my new hair to complete disappointment.  


In 3 weeks, my hair had already gone back to its normal state. It even was worse than it was before I had done the keratin.

I went from showing of my radiant hair to having horrible hair.

It was if the treatment had completely washed away.

I didn’t really understand what happened.
And to make things worse, I was so angry like you wouldn’t believe because as you know well, keratin is an expensive treatment.


Until I consulted with a friend who also had done a keratin treatment a few months before I did and her hair still looked like she had recently done it.

Her answer was blunt: In keratin treated hair, the best option is sulfate-free shampoo.”

My eyes popped out of my head.


I remember that my stylist had just finished doing the keratin treatment and she had recommended that I use a sulfate-free shampoo. How could I have passed over something so important?

After blaming myself, I looked at my hair and it was imposible to not make comparisons.


Her hair was shiny. Mine, although freshly washed, looked dull and lifeless.

Without wanting to, I wished for her hair.

Her highlights were soft and faded through my fingers. Mine felt porous and had a certain dryness that started to worry me.

Her hair had absolutely no frizz. On the other hand, my started to softly bristle.

Not being dumb or lazy, I asked for some recommendations about sulfate-free shampoos for keratin-treated hair.


She asked me for a pen and paper to write down some names, and I put it away quickly, as if it were a one hundred dollar bill.

Do you want to know which sulfate-free shampoos she recommended to me?


I’m ready to share that information with you, but let me first tell you about the importance of taking care of keratin treated hair.

Why it’s important to care for keratin treated hair

take care after treatment

If you have done a keratin treatment, you know that it doesn’t end when you leave the stylist. It requires special care to make the treatment last longer in your hair. Because of that, you should pay attention to certain questions.

If you are about to do a keratin treatment in your hair, even better, because you will know the little secrets for caring for your keratin treated hair.

Traditional shampoos conatin a lot of sulfates which you can find in the ingredients list of every product, like sodium lauryl sulfate or sodium laureth sulfate.

You may also see SLS or SLES.


This ingredients work against the health of your hair. Get rid of them completely for use in keratin treated hair. What they do is remove the natural oils in  you hair which interact with keratin, dissolving it.

Also, they can damage the skin on your scalp drying it out and causing eczema.

They can also weaken the hair fibers, giving your hair a tendency to break and fall out easily.


If you have colored hair, shampoos with sulfates can strip out the color, which creates this vicious cycle of dye, more dye, more dye that just damages your hair.

Sulfates in the shampoo leave stains in the hair follicles which in many cases weakens the hair and causes hair loss.


But don’t worry, there is still time, just like I was able to repair my keratin-treated hair using sulfate-free shampoo.

Now comes the time to keep my promise.

Here are the top three sulfate-free shampoos that my friend recommended to me and that will give you results.

What’s incredible about this sulfate-free shampoo is that  every time I use it, my hair looks like I just left the salon.   Yes, just like you read it.

It’s as if this shampoo renews my keratin every time I use it.


Maybe its because it doesn’t have sulfates, nor parabens, nor any aggressive chemicals that the traditional shampoos from the supermarket have. Or maybe it’s because it’s made with natural ingredients like argan.

Be it as it may, this shampoo works miracles on my keratin treated hair. It leaves my hair looking like I just left the salon. But there’s more that excites me about this shampoo.


I’m going to save a fortune.

Before starting to use this shampoo, I had to get my keratin redone once a month. Because after three weeks, my hair looked horrible.

With this shampoo, my hair stayed beautiful for at least three or four months.


So now you know that if you want your hair to look beautiful for a long time, and on top of that, save a fortune, I recommend this shampoo. You’re not going to regret it.

Let’s review some of the benefits of this shampoo.


  • That natural oils and vitamins included in the formula of this sulfate-free shampoo provide shine and smoothness to hair treated with keratin
  • Smooth scent, almost imperceivably for those that are sensitive to smells. The formula is good for all hair types

Of course, there’s always a favorite.


In my case, I use the sulfate-free Argan Oil shampoo from Arts Naturals.


Now that I’ve gotten the smoothness and the shine back in my hair, when I see my friend, we laugh at my desperate face from a few months ago when I thought that nothing would make my hair look healthy and radiant again.

We even tried to guess which of the sulfate-free shampoos we washed our hair with that day.


To end with, I prepared a bonus track, some advice to lengthen the effects of a keratin treatment in addition to using any of these three fabulous sulfate-free shampoos.


Tips to draw out the effects of keratin in your hair

  • Once you get the keratin treatment done, don’t expose your hair to pool water, ya because chlorine can strip out the effects of the protein.
  • Along the same line as the previous point, try to avoid continuous exposure to the sun. If you are exposed to the sun for long amounts of time, you can use a sunscreen for your hair.
  • Three days after getting the keratin treatment done, you can wash your hair with one of the three sulfate-free shampoos that I previously recommended.
  • If you dye your hair, remember to do it two weeks after the keratin treatment, especially if you dye your hair black or dark brown.
  • Don’t abuse the heat tools like flat irons and hair dryers. If you use the hair dryer, use one with heat regulation like CHI.


Lastly, these days, it’s important to contribute to caring for the environment. Try to use shampoos and conditioners that are sulfate-free because they are completely sustainable.

What more can you ask for? You care for the planet while you care for your hair.
