Notice to customers in the United States

The customs charge (approximately $54) that some orders receive is not applied by our company, but by US Customs and Border Protection due to a legal change effective September 2025 that eliminates the de minimis exemption for imports. This duty is mandatory and beyond our control. Thank you for your understanding.

Frequent questions

Why is it important to use a post-straightening kit after a keratin treatment?

Because it helps prolong the smoothing effect , preventing the treatment from wearing off with washing. This kit is formulated without salt or sulfates , so it doesn't strip the keratin and keeps hair frizz-free for longer.

Does it work if I don't have keratin-straightened hair?

Yes, although it is designed to maintain straightening, it also improves any type of hair thanks to its anti-frizz action, deep hydration and 3D shine , even on dry or dull hair.

How often should I use the shampoo and hair mask?

It's a daily or regular routine , depending on how often you wash your hair. The shampoo gently cleanses, and the mask can be used as an ongoing treatment since it's free of salt and harsh sulfates.

What are its advantages compared to a regular supermarket shampoo?

Unlike commercial shampoos that often contain sulfates and salt, this one doesn't remove the straightening treatment . It also includes Blend Protein and Amino Complex , which nourish, repair, and seal the cuticle , leaving hair shiny and frizz-free.

Does this kit add volume or reduce it?

Its formula controls frizz and static electricity , as well as improving hair manageability , resulting in a more polished finish with less unwanted volume .

Does the hair mask leave hair heavy or greasy?

No, its formula is designed to hydrate from within the hair fiber and seal the cuticle without weighing it down. It's applied only from mid-lengths to ends to keep hair light and with natural movement.
