Top Five Shampoo Brands for Keratin-Treated Hair

Beautiful woman with keratin treated hair

After spending money and time to smooth and shine your locks, you want to ensure that such a sleek look and silky feel last as long as possible. The products you use after treatment make a big difference. Unfortunately, most commercial shampoos use harsh detergents and keratin-dissolving ingredients that can strip the treatment from your hair.

To maintain the benefits of your keratin treatment, your shampoo needs to be free of sodium chloride, sodium laureth sulfate, and sodium lauryl sulfate. Only use a shampoo that meets those requirements.

Keratin-infused shampoos can provide additional benefits to keratin-straightened hair. Hydrolyzed keratin, hydrolyzed wheat protein, hydrolyzed silk, and amino acids help also tame frizz and boost softness and smoothness. The benefits of using keratin-replenishing shampoos and conditioners 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.

Using 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 without 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.

1. 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.

2. 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 colored and chemically treated hair. It helps to extend the time between hair washing, which can prolong the life of your keratin treatment.

Choosing Your Post-Keratin-Treatment 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 effectively 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 that dissolves keratin and can negatively affect your treatment. Shampoos with sulfates 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 keratin-infused products, but be sure it’s salt 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 vs. Keratin-Safe Shampoos

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

That sounds great, but these shampoos are not necessarily free of salt and sulfates. Some brands contain SLS or claim to have a “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 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. You are right. This shampoo/conditioner set is also sodium chloride free as it supposed to be used for keratin-treated hair.

  4. 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

  5. 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

  6. 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.

  7. 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 it’s all safe or not???? How I take care of my hair I am very tense.

  8. 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.


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

  10. Not all alcohols are drying and bad for your hair. Fatty alcohols, such as cetyl alcohol, Cetearyl, and stearyl alcohol have moisturizing, detangling, and soothing 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. These alcohols are very drying and may cause your hair to be dried and frizzy. Alcohols such as isopropyl, propanol, propyl, ethanol, and SD Alcohol should be avoided in most cases, especially if listed as one of the first four ingredients.

  11. 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.

  12. Ridiculous. Theorie Helichrysum shampoo not only contains SODIUM LAURETH SULFATE, but it also 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?

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

  14. 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..can’t return it anymore…so pay attention to ingredients because it’s not all suitable even though it says it is.

  15. I just got my Keratin Treatment. My hair is too thin & treatment made it look limp. Please, advise what shampoo to use since my hair has no body.

  16. Check the ingredients, please. Go to the EWG website and put some of the ingredients inside the search bar.

  17. 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, Linalool “

  18. 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.

  19. Yep, using a salt-free shampoo is the way to go after getting a keratin treatment or the results won’t last. The sulfates or salt just strips the treatment of your hair.

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

  21. 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 depressing product made my smoothing therapy look natural even after months have gone by since the treatment. Remember, keratin protein is absorbed water and that absorption is what keeps 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 it’s wearing off in two months. Beauty Vice sells much of Keratin Complex stuff on their website if you are interested. Awesome article.

  22. 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

  23. 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.

  24. 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!

  25. 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.

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

  27. I have low porosity hair and got myself a hair Botox done, it’s a much better version a keratin treatment and even the aftercare 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 maintenance 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 something which will cleanse my oily scalp and is protein-free? It would mean a lot since I’m really struggling with the aftercare.


  28. 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.
