How does the Bond Re-Plex technology actually work in this hair dye, and will it make my hair feel stronger after coloring?

The Bond Re-Plex technology in this formula incorporates amino acids, which are small molecular building blocks. During the permanent coloring process, these amino acids can integrate with the hair fiber as the dye develops. This integration aims to help reinforce the hair's internal structure during the chemical exposure, which in practical terms often results in hair feeling less brittle and rough after rinsing compared to some permanent dyes without similar ingredients. It's important to understand that this is a cosmetic treatment focused on the condition and feel of the hair during and immediately after the procedure, not a structural repair treatment for significantly damaged hair. The combination with oleic acid further contributes to a smoother feel by helping to soften the hair cuticle. For best results, the creamy texture of this dye also aids in even application, which helps minimize uneven processing that can lead to patchy damage.
