8 Best Sulphate Free Shampoo For Keratin Treated Hair 2022

Using a sulphate free shampoo for keratin treated hair is all the rage right now. These prevent your keratin-treated hair from getting damaged or turning dry and frizzy.

Sodium Lauryl Sulphate or SLS and Sodium Laureth Sulphate or SLES are substances that are commonly added to shampoos and other hair products. 

They are extracted from petroleum and other plant sources like palm and coconut oil. Their primary function is to help you build a lather while using the shampoo.

Sulphates are also excellent cleansing agents that can get rid of any dirt or buildup from your hair. 

However, they also come with a set of cons that will make you reconsider your choice of shampoo. 

They remove not only excess oil and dirt but hair’s natural moisture, making tresses dry. Sulphates are also known to strip hair dye from strands.

Keratin treated hair is already vulnerable as they’ve been through a rigorous chemical rebonding process.

And using sulphate-based shampoos can damage hair further and leave it frizzy and untamed. Which is basically undoing a keratin treatment!

Why you should use a sulphate free shampoo for keratin treated hair

If you haven’t found enough reasons to stop using shampoos with sulphates, let us take an in-depth look into some of the benefits of sulphate-free shampoos. 

Strengthens hair

When your hair ends up being dry and brittle, it becomes fragile and thin. This will lead to a spike in hair fall. 

Sulphate-free shampoos, on the other hand, can help in avoiding this issue and make your hair stronger. 

They also contain many natural ingredients that can reinforcee the strength of your hair roots and make them immune to hair fall and breakage. 

Reduces scalp irritation

Excessive chemicals in any hair products are bad news for those with a sensitive scalp.  If you have a sensitive scalp, sulphates can aggravate your issues. 

You can experience itching and dryness of the scalp after using such chemical loaded hair products. But using a sulphate-free shampoo alone cannot fix your scalp issues. 

There are other harmful chemicals like parabens and mineral oils that could result in scalp inflammations and irritations.  

Protects hair color

Hair colour can fade quickly as you wash your hair, especially with shampoo. Most of them only stay intact for three to four washes. 

Sulphates are harsh chemicals that have the potential to make your hair colour fade. Using a shampoo with sulphates has a greater chance of stripping colour from your hair. 

Since most sulphate-free shampoos are colour safe, you do not have to worry about this. 

It preserves the permanent or semi-permanent colour on your hair and does not wash it off while showering. 

Doesn’t strip the natural moisture from your hair

This is perhaps the most important benefit of a sulphate free shampoo. Our scalp produces natural oils that are necessary to have healthy hair growth. 

When you use regular shampoo with sulphates, it dehydrates your hair in the process of cleaning by stripping these oils from your strands.

A sulphate-free shampoo can balance the moisture on your scalp and protect your hair from being dry and brittle. 

Sulphates are strong chemicals that can strip the natural moisture from your hair. 

It is an ingredient that can adversely affect your keratin-treated hair so make sure that you never use hair products with sulphates in them.

These harsh surfactants will make your hair dry, brittle and rough. 

If you’re shampoos with sulphates, it can also affect the quality of your Keratin treatment. 

Plus, if you have a sensitive scalp, it can also lead to scalp irritations and inflammations. 

So I always recommend using a sulphate free shampoo for keratin treated hair to keep your tresses silky straight and soft.
