Shampoos Without the Boos: Choosing Your Post-Keratin-Treatment Shampoo

While you don’t have to use shampoo and conditioner from the same line as your keratin treatment, you can flexibly aim for shampoos with the books. Select keratin-friendly products, regardless of brand, to effectively meet all your aftercare needs. Cheers to that freedom of choice!

When purchasing your products, carefully read all labels carefully to ensure no harsh ingredients that will ruin your treatment.

Steps when choosing your aftercare shampoo are 3-fold:

1. Don’t Date Sulfates: Avoid Sodium Chloride and Sulfates. To maximize the longevity of your treatment, choose only shampoos free of harsh sulfate cleansers such as sodium laureth sulfate and sodium lauryl sulfate. Shampoos with sulfates can remove straightening chemicals from your hair.

Sodium chloride is a thickening agent that dissolves keratin and can undo hair straightening results. Make sure to only use a shampoo that says “sayonara” to sodium chloride!

Be the best version of yourself, not a lab rat! Beware of hidden chemicals in your products. Because your hair has already undergone a chemical treatment, you don’t need additional chemicals to impose additional harm. Scan your brands to avoid parabens and formaldehyde—both dangerous chemicals—so beware!

2. Pucker Up With a KISS:  Strive for KISS products, not the smooches or the rock bad, but KISS as in Keratin-Infused Shampoo Selections. Although you don’t necessarily need keratin-infused products exclusively, these products offer additional benefits to keratin-straightened hair. Hydrolyzed keratin, hydrolyzed wheat protein, hydrolyzed silk, and amino acids tame frizz and boost softness and smoothness.

When your keratin treatment starts to wear off, the higher hair porosity will allow for easier penetration of keratin particles into the hair cortex, delivering a shield for your shine!

3. Be Savvy Against Deceptive Labels. Some brands of “keratin-replenishing shampoos” aren’t sodium-chloride- and sulfate-free. Some manufacturers falsely advertise that their products are suitable for use after a keratin treatment, even though they still contain sulfates. Be savvy to read between the lines to keep your hair gorgeous and fine!

Say “Hi” to Dry: Using Dry Shampoos After Keratin Treatment

If you’ve had a keratin treatment or a Brazilian blowout, you still can use a dry shampoo to keep your hair looking fresh. Don’t be shy to say “hi” to sulfate-free dry shampoos. They come in 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 must avoid washing your hair.

Stylists believe that it’s absolutely 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.

  • Loma Dry Shampooicon: Loma products are paraben-, gluten-, sulfate-, and sodium chloride-free, so you can be assured that this dry shampoo is good for your hair and scalp. It will not harm your keratin treatment in any way and will leave your hair looking fresh and smelling clean.
  • Living proof Perfect Hair Day Dry Shampoo (Walmart) absorbs grease and sweat and eliminates odors, leaving the hair feeling fresh and clean. Patented Healthy Hair Molecule (OFPMA) technology helps to easily brush out the powder 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 can help to extend the time between hair washing, which prolongs the life of your keratin treatment.
  • Briogeo Scalp Revival Charcoal Biotin Dry Shampoo is designed to absorb excess oil, normalize oil production, and nourish your scalp. Unfortunately, this quality, naturally based, and cruelty-free shampoo powder comes in inconvenient packaging that can make it hard to control the amount you want to apply.

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.

35 thoughts on “Five Shampoo Brands for Keratin-Treated Hair”

  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.
