Top Five Shampoo Brands for Keratin Treated Hair

If you’ve invested in a keratin treatment to smooth and shine your locks, you want that sleek look and silky feel to last as long as possible. The products you use afterward make a big difference. Most commercially available shampoos can strip the treatment from your hair because they are filled with harsh detergents and keratin dissolving ingredients.

Your post keratin shampoo is supposed to be SLS and salt-free. Only use a shampoo that meets those requirements.

Shampoos that contain hydrolyzed proteins can provide additional benefits to keratin straightened hair. Hydrolyzed keratin, hydrolyzed wheat protein, and hydrolyzed silk help tame frizz and provide softness and smoothness once your treatment starts to fade.

Sulfate and Salt-Free Shampoos for Keratin Straightened Hair

The following sulfate and salt-free shampoo brands are keratin treatment friendly and formulated mainly with natural ingredients such as plant-based cleansers, hydrolyzed proteins, plant oils, and botanical extracts.


Moroccan Argan Oil Shampoo and Conditioner by LuxeOrganic’s are made with organic ingredients that will nourish your hair, making it look healthier and shinier. This shampoo doesn’t lather like sulfate-containing shampoos, but it cleans effectively without drying or stripping your hair.

This set contains All-Natural Moroccan Argan Oil that your hair will instantly absorb, resulting in gorgeous shine and absence of frizz. It contains UV absorbers designed to protect hair from harmful UVA and UVB rays and prevent fading of color.

Amino acids help repair hair damage and improve tensile strength, while vitamins and antioxidants nourish hair and protect it from styling damage. The rejuvenating Argan Oil Conditioner moisturizes, detangles, and adds volume without creating buildup or weighing hair down.

These products contain no sulfates or sodium chloride. They are suitable for all hair types, including colored and chemically straightened hair.

Both the conditioner and shampoo have a sweet citrus scent.


Oribe Ultra Gentle Shampoo is formulated to provide your hair with weightless moisture, softness, and shine.

It is formulated without harsh sulfates and sodium chloride, so it is safe for colored and keratin treated hair.

The formula is very gentle on chemically treated hair and has a soothing effect on the scalp. It doesn’t foam up as much as sulfate containing shampoos but cleans very well leaving your hair softer and more manageable. A gorgeous smell is the same as most Oribe products.

Oribe Signature Complex (Watermelon, Lychee and Edelweiss Flower Extracts) prevents damage of natural keratin, protects hair from elements, and prevents color fading.

This shampoo contains UV Protection System that protects your hair from sun damage and prevents discoloration.

Hydrolyzed Soy Protein strengthens hair fibers, enhances manageability, and adds shine.


Salt & Sulfate Free Shampoo and Nourishing Conditioner – Keratin Complex by Damila is formulated to enhance the results and extend the life of your keratin treatment. This shampoo uses a mild surfactant to gently cleanse chemically treated hair including colored and keratin straightened hair.

The set contains Hydrolyzed Keratin, Silk Amino Acids, and Hydrolyzed Silk Protein to replenish lost keratin and rebuild the strength of chemically treated hair

Natural and botanical extracts nourish and hydrate your hair, leaving it soft, healthy, and shiny.


Pure Brazilian – Anti-Frizz Daily Shampoo and Conditioner are formulated to deliver moisture and keratin to keep your hair smooth and manageable. This duo can be used on all hair types but it is especially suitable for calming thick and curly/coarse hair.

Anti-Frizz Shampoo is formulated without harsh sulfates and sodium-chloride to gently clean your scalp and hair without stripping your keratin treatment or hair color. It’s made with Hydrolyzed Vegetable Protein to infuse your tresses with keratin and maintain optimal smoothness. It leaves your hair softer, frizz-free, and shiny.

Anti-Frizz Daily Conditioner is an ultra-moisturizing conditioner formulated with keratin amino acids, mango seed butter, and hydrolyzed collagen to rehydrate dry hair and protect it from styling and environmental damage. With regular use, it helps strengthen and seal hair’s cuticle, to preserve hair color and create a healthy shine.

Benefits of using keratin replenishing shampoo and conditioner are more obvious when your keratin treatment starts to wear off because the higher hair porosity will allow for easier penetration of keratin particles into the hair cortex.


Shampoo and Conditioner Sulfate and Salt-Free for Keratin Treated Hair by Smart Protection are designed to hydrate and strengthen the hair and prolong the effects of keratin straightening treatments. Both products are infused with hydrolyzed keratin to replenish damaged keratin and strengthen the hair structure making it more resistant to breakage. Amino acids create a protective layer over the hair cuticles to prevent moisture loss, making hair healthier, shinner, and more manageable.

Panthenol and Aloe Vera work to replenish lost moisture, leaving hair smooth and less prone to frizzing. Sunflower oil helps to seal the cuticle and lock in moisture inside your hair.

Benefits of using keratin replenishing shampoo and conditioner are more obvious when your keratin treatment starts to wear off because the higher hair porosity will allow for easier penetration of keratin molecules into the hair cortex.

Dry Shampoos After Keratin Treatment

If you have had a keratin treatment or a Brazilian blowout, you still can use a dry shampoo to keep your hair looking fresh. Sulfate-free dry shampoos come in a powder form to help absorb oil while not interfering with keratin treatments. Those dry powders will be your best friend during the 72-hour phase when you have to avoid washing your hair. Stylists believe that it is safe to use dry shampoo to refresh your style without water when your hair gets greasy, but you should choose a product formulated to help preserve your results.

Living Proof Perfect hair Day Dry Shampoo absorbs all the grease and sweat and eliminates odor, leaving the hair feeling fresh and clean. Patented Healthy Hair Molecule (OFPMA) technology helps to easily brush out the powders leaving your hair really clean. A time-released fragrance delivers a light, refreshing scent throughout the day.

This dry shampoo is safe for color and chemically treated hair. It helps to extend the time between hair washing, which can prolong the life of your keratin treatment.

Keratin Complex Volumizing Dry Shampoo Lift Powder – Blonde helps extend the life of keratin smoothing treatments by decreasing the frequency of your washes. This product comes with a built-in brush in a small, travel-friendly container. It is available in different colors, and you can order refills. The brush applicator allows you to apply the powder to certain oily areas, and the slightly fruity smell doesn’t linger. The white traces in your hair disappear after you brush the product through. A color option for brunettes is also available.

How to Purchase Post Keratin Shampoo

You don’t have to use shampoo and conditioner from the same line as your keratin treatment. Keratin-friendly products, regardless of brand, will efficiently meet all your aftercare needs.

When purchasing your products, you must read labels carefully to make sure there are no harsh ingredients that will ruin your treatment.

Here’s what you should be aware of when choosing your aftercare shampoo:

Avoid sodium chloride and sulfates.

To maximize the longevity of your treatment, stay away from sodium chloride and sulfates; they can undo hair straightening results, and they can be in both shampoos and conditioners. Sodium chloride is a thickening agent which dissolves keratin and can negatively affect your treatment. Shampoos with sulfate can remove straightening chemicals from your hair.

Labels can deceive.

Some brands of “keratin replenishing shampoos” are not sodium-chloride and sulfate free. Some manufacturers falsely advertise that their products are “suitable for use after keratin treatment” even though they contain sulfates.

You don’t necessarily need a product that’s “keratin infused,“ but do be sure it’s sodium and sulfate free.

Watch out for other chemicals.

Your hair has already undergone a chemical treatment, so you don’t need additional chemicals on your hair or skin that can be harmful to your health. Certain brands contain parabens or even formaldehyde—both dangerous chemicals—so beware.

Keratin Shampoos v.s Keratin Safe Shampoos

Keratin infused shampoos are designed to strengthen hair and provide smoothness and frizz control by repairing and filling weak areas inside the hair fibers.

That sounds great, but these shampoos are not necessarily free of salt and sulfates. Some brands contain SLS, or they are labeled as “lower sulfate formula.” Examples include Tresemme Keratin Smooth Infusing Shampoo and Suave Professionals Keratin Infusion Smoothing Shampoo.

And then there are some sulfate-free formulas that still contain sodium chloride, such as Burgati Keratin & Argan Oil Professional Series Shampoo.

If you are skeptical about the ingredients of your post-keratin shampoo, consult a reliable hair professional or a dermatologist to make sure that the product meets your needs.

  1. After seeing this list I just so happened to run into the Theorie shampoo and conditioner at my local TJMaxx for half of the normal price and it’s amazing!!

    I got my keratin treatment 2 days ago but tried the shampoo and conditioner before to see if it was any good. It made my hair so shiny and soft, all before keratin!

    I’m currently waiting in my 72 hour period until I can wash my keratin out but I have to say I think the shampoo and conditioner will help a lot in maintaining my keratin.

    I purchased the Theorie shampoo and conditioner set but in a different kind – the Ultimate Reform Argan one and highly recommend it!

    So happy I found Theorie on this list because even though I’m pretty savvy about beauty brands, I’d never heard of them!!

  2. Hi

    I saw your post on the Theorie shampoo & conditioner but I didn’t see any mention of it being chloride free which was another I was supposed to avoid can you tell me if it is?

    Many thanks

  3. Great article, really helped me out. As soon as I read it I saw the Keratin Complex Smoothing Therapy was the best pick for me then went to the mall straight away. A bottle was $40 NZD each but it’s gonna be worth it in the long run. I bought 4 bottles worth of ‘Natural World’ shampoo for keratin? Then I read it just had different kinds of sodium so it’s sort of a scam. Thanks again :DD

  4. Hi Nina, you bought Keratin Complex shampoos in NZ. so they must be available in Australia too. Can somebody suggest me from where I can buy this in Sydney? Thanks

  5. What about the O&M brand? I bought the hydrate & conquer shampoo after my keratin complex treatment. It’s not tested on animals as well.

  6. Please kindly suggest me 15 of Oct 2015 I did my rebounding and after 2 days that saloon did my spa with wash and finally 27 of Oct 2015 they did keratin also pls tell me its all safe or not???? How I take care of my hair I am very tense.

  7. Along with everything else mentioned, I am also not supposed to use anything with Alcohol ingredients? So I am guessing these shampoos do not have any of that either. I have gotten keratin treatments before and knew about needing sulfate-free shampoos but have never heard about the Alcohol free thing.


  8. Hi Madeenie,
    I tried the Tjmax store but couldn’t find the helichrysum one of the theorie brand, instead there was some other shampoos of theorie. Do u know any other shops here in London , from where I can get that one??
    Many thanks,

  9. Not all alcohols are drying and bad for your hair. Fatty alcohols, such as cetyl alcohol, cetearyl, and stearyl alcohol have moisturizing, detangling, and smoothing properties and help to make your hair soft and manageable.

    Short-chain alcohols are added to hair products to help hair products evaporate quickly and last longer. Those alcohols are very drying and may cause your hair to be dried and frizzy. Alcohols such isopropyl, propanol, propyl, ethanol, and SD Alcohol should be avoided in most cases, especially if listed as one of the first four ingredients.

  10. I have “after chemo” hair is somewhat is fine, dry and frizz. What would be recommended? I have moroccan oil I put on after shampoo/conditioner while wet. I think it needs more “nourishment”. Have tried a lot of products.

  11. Ridiculous. Theorie Helichrysum shampoo not only contains SODIUM LAURETH SULFATE, it says so right on the ingredient label and if you call the company they will tell you it’s in there. Yet every advertisement and review states that it does not. What’s the deal?

  12. You are absolutely right. There are two versions of ingredient list on sellers’ websites. I apologize for any inconvenience may have caused.

  13. I got the one with SLS in TKmaxx, it says safe for keratin treated hair but obv isn’t.
    I’m not happy as it’s quite expensive..cant return it anymore…so pay attention to ingredients because it’s not all suitable even though it says it is.

  14. Just got my Keratin Treatment. My hair is too thin & treatment made it look limp. Plse, advise what shampoo to use since my hair has no body.

  15. are any of the following ingredients going to be harmful to my keratin treatment? (it’s dry shampoo)
    “Isobutane, Propane, Alcohol Denat., Oryza Sativa (Rice) Starch, Cellulose, Octafluoropentyl Methacrylate (OFPMA), Caprylyl Glycol, Dipropylene Glycol, Citronellyl Methylcrotonate, Hydroxypropylcellulose, Hydrated Silica, Cetrimonium Chloride, Zeolite, Ethylcellulose, Octoxynol-10, Disteardimonium Hectorite, Water, Fragrance, Ethylhexylglycerin, Phenethyl Alcohol, Limonene, Citronellol, Hexyl Cinnamal, Benzyl Salicylate, Butylphenyl Methylpropional, Citral, Lianool “

  16. What about a product called Plarmia Hairserum Shampoo (and conditioning treatment) distributed from Milibon USA? The second ingredient in the shampoo listed is Sodium Laureth Sulfate.

  17. Can you please give a brand that they would carry at a beauty supply store? Besides brazilian blowout for shampoo and conditioner. (Cosmoprofesionals)

  18. I am surprised that only the volumizing dry shampoo was the only thing mentioned in this article from Keratin Complex. They have a massive selection of post procedure shampoos and conditioners. I get a smoothing therapy treatment all the time and they always react so much better with Keratin Complex after “smoothing treatment” products. The one thing that isn’t mentioned enough and has been my saving grace was the purple shampoo. This debrassing product made my smoothing therapy look natural even after months have gone by since the treatment. Remember, keratin protein is absorbs water and that absorption is what keep your hair staying straight. While other products like the Brazilian Blowout have a faster recovery time from the procedure, Keratin Complex locks in for longer, giving a more quality look that doesn’t feel like its wearing off in two months. Beauty Vice sells much of Keratin Complex stuff on their website if you are interested. Awesome article.

  19. Hi, I have got this 2chic Brazilian Keratin & Aryan oil shampoo. Please suggest if this is safe for my keratin treated hair. Sending the website for more information

  20. You have made the right choice. Your shampoo doesn’t contain sulfates, sodium chloride, parabens or synthetic fragrances. It is gentle to your keratin treated hair and good for your body. It also contains hydrolyzed keratin proteins, which can penetrate the hair shaft to repair damage and increase tensile strength.

  21. Hi! Wondering if the ACURE you mentioned above is safe. The label says it contains Sodium lauroyl methyl and sodium benzoate. Is that the harmful Sodium?

    thanks for the info!

  22. Sodium chloride or table salt is used as a thickener in SLS containing shampoos. The salt can dissolve the keratin coating and shorten the life span of the treatment.
    Sodium Lauroyl Methyl Isethionate is a water soluble, coconut derived, surfactant that has proven to be mild and gentle. It will not harm your chemically straightened hair.
    Sodium Benzoate is used as a preservative in personal care products, but not in this shampoo.

  23. GK Hair Moisturing Shampoo and Conditioner are awesome for mainting treatment! They even made my dandruff go away. Highly recommend GK Hair

  24. I have low porosity hair and got myself a hair Botox done, it’s a much better version a keratin treatment and even the after care is similar. But the issue if all the keratin/ Botox friendly shampoos are so hydrating and not for oily hair type. I started using keratin therapy maintainace shampoo by alfaparf and I love how it leaves my scalp and hair squeaky clean but since it has keratin which is a protein it makes my hair very dry sort of wiry. Can you please recommend me something which will cleanse my oily scalp and is protein free? It would mean a lot since I’m really struggling with the after care.


  25. You can try Degrease Shampoo for Oily Hair and Scalp by Maple Holistics. It is free of sulfates and sodium chloride. It contains botanical keratin, but it is well balanced with moisturizing ingredients.
