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—and 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 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.
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.
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 set is formulated to deliver moisture and keratin to keep your hair smooth and manageable. It can be used on all hair types but it is especially suitable for calming thick and curly/coarse hair.

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.
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.

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