With citric acid and bonding care complex that repairs weakened hair bonds, providing resistance and strength to the hair from within the fiber.
ACIDIC BONDING CONCENTRATE
Deep conditioning shampoo, provides strength and respects colored hair. Our most concentrated formula to date.
CONCENTRATED FORMULA
Acidic Bonding Concentrate is a treatment that repairs, hydrates and protects against loss of color in the hair. This range is made up of 3 references. Use of the full treatment is recommended for best results.
Acidic Bonding is a good shampoo. What I don’t like is the smell of the product. I also use All soft which has a better smell. Both products are good for curly hair

Perfect
Silicone-free shampoo that leaves your hair perfectly clean, protected, and with a very pleasant scent. Highly recommended.

More strength and shine in the first application
This shampoo has helped transform and improve my hair since the first application. It feels stronger, healthier and has incredible shine. Plus, it cleanses deeply without drying it out. Perfect for damaged hair!

Very good
This shampoo left my hair softer and more manageable from the first use, as well as giving it spectacular shine. I love how it strengthens and repairs my damaged hair while protecting it with its acidic pH formula.

The shampoo is super cool, easy to apply, leaves hair super clean and soft. It also gives hair an ideal texture and more strength. I notice my hair is healthier and stronger than ever. I have used it with the brand’s conditioner and the combination has been the best.

Good product
I liked this shampoo, although I think it’s not the best for my hair type. I really liked the feeling of softness it leaves and, together with the rest of the products, my hair feels and looks much healthier, softer and frizz-free. However, I feel like I lack a bit of volume because my hair is too fine. I think it should be perfect for another type of hair.

Hello, Thank you for contacting us. Yes, this is not a product for a specific hair tone. We remain at your disposal. Cheers.

Does it work like violet shampoos? That is, will the color of my highlights lighten?
Translated by Google
Andrea02/10/2021
Good morning Andrea, No, it is not a product that lightens or tones the blonde tone. It does provide a lot of shine and softness, but it does not fulfill the function of a shampoo with violet pigments. We remain at your disposal. All the best.
