If you’re struggling with a certain hair issue, there is no dearth of hair treatments to help you out. But choosing the right treatment for your specific hair concern and hair type is extremely important. If you want to tame frizzy and unruly hair, chances are you’ve heard of keratin and smoothening treatments as a solution. 

While they both aim to enhance hair texture, there are important distinctions between the two. In this blog post, we will explore the features of keratin vs smoothening treatment, and highlight their differences to help you make an informed decision for your hair care regimen.

What is Keratin Treatment? 

Keratin treatment is a chemical process that involves the application of a keratin-based solution to the hair, which is then sealed using heat. This treatment replenishes the natural keratin protein in the hair shaft, reducing frizz, adding shine, and improving manageability. 

Keratin treatment works by smoothing down the hair cuticles, which are the outer protective layers of the hair shaft. This process helps to repair and strengthen the hair, making it more resistant to humidity and external damage. 

Our experts recommend System Professional Luxeoil Keratin Conditioning Cream which protects the keratin and the hair fibre from the stress of hair styling. It deeply conditions and smoothens the hair resulting in nourished and frizz-free locks.

What is Smoothening Treatment?

Smoothening treatment, also known as hair rebonding, is a chemical process that alters the structure of the hair to make it straight and sleek. It involves the application of a relaxer or a straightening solution, followed by the use of a flat iron to seal in the new shape.  This process typically takes several hours and requires the expertise of a professional stylist. The smoothening treatment permanently changes the hair’s texture, eliminating frizz and creating a pencil-straight appearance.
