Cationic polymers act as vehicles that optimize the penetration of dyes in order to achieve long-lasting color with complete coverage from the roots and maximum expression of the hair’s natural sheen.

How do the polymers work? These polymers generate particles with a positive charge which adhere to the negatively charged molecules found in the hair. By facilitating the fixation of the pigments during the coloring process, it is possible to increase color intensity and durability.

Both the COLLAGE and GLOSS lines of color incorporate this system of formulation, and each of them includes natural ingredients with high moisturizing and filmogenic properties in its cosmetic base. The hair becomes stronger and looks healthy and shiny after dyeing.
