Rather than evaluating their safety and efficacy, people are blindly purchasing products based on advertising and popularity. Selecting the right shampoo is critical for the longevity of your hair, especially if you’ve chosen keratin treatment. In this article, we will review how to choose the best keratin sulfate free shampoo for you.

What is Keratin?

Keratin is a vital structural component made of protein that creates the outer layer of our hair, skin and nails. By repairing cracked or damaged cells, it provides hair with strength, elasticity and vigour. As the amount of keratin in our cells decrease, our hair becomes more fragile, brittle and dry.

Why do we need Keratin Shampoo?

The function of keratin shampoo is to provide your hair with adequate amounts of this protein. With additional keratin, your hair will regain its elasticity and finally be free of damage, split ends, and uncontrollable frizz. With a combination of keratin hair straightening and shampoo, women have been able to achieve a smooth, silky, and shiny hair texture that they never imagined possible. In addition, the ingredients found in many keratin shampoos provide UV ray protection, making it ideal to use outdoors.

A keratin shampoo is ideal for curly hair because it reduces frizz, making it exponentially easier to comb after washing. With less scalp and hair trauma due to comb pulling, the chances of premature balding and hair loss is significantly reduced.

Why choose a Sulfate Free Keratin Shampoo?

As mentioned in the Truth About Sulfates, sulfates are harsh detergents that can strip your hair and skin of its natural oils, rendering it dry, weak and damaged. Consequently, sulfates can be particularly damaging to keratin treated hair.

Certain keratin shampoos contain an ingredient known as Paraphenylene diamine (PPD) which has shown to cause scalp irritation, allergic reactions, and dandruff in sensitive individuals. Therefore, we recommend choosing a shampoo that is free of both sulfates and PPD.

Sulfate Free Keratin Shampoo and Conditioner


Generally, keratin shampoo is well tolerated. But for certain individuals, particularly for those with a drier scalp, the shampoo may be slightly irritating as it can reduce moisture. This is normally not an issue for those with a normal to oily scalp. That is why we strongly suggest individuals with dry scalps to use a separate conditioner to avoid the risk of developing irritation and to provide stronger and healthier looking hair.

We personally recommend Keratin Complex Care Conditioner. This product is 100% sulfate and sodium free and can fortify the keratin used during the treatment procedure. Use the conditioner after shampooing your hair, leave it on for at least 1 minute, then it rinse it out thoroughly.

There are many shampoos indicated for keratin-treated hair. Unfortunately, many of these products are not sulfate free and can actually damage your hair.

Following extensive research, we narrowed the choices down to a single product that stood out from the rest: Keratin Complex Color Care Shampoo.

How long does it take to see the results.

Hey Juanita,

Great question. The answer really depends on your hair type and the level of damage your hair already has. These 2 factors will affect how well the product will work. Although keratin shampoo is effective for most hair types, it can be especially beneficial for frizzy, dry or curly hair. Since keratin will take time to build up on the hair and undergo keratinization, you definitely won’t see immediate results. For average dry hair that is not excessively damaged, I’d estimate that it would take at least a week to see results.
