Aniline derivative tints do what to the hair shaft? - Answers

Aniline derivative tints penetrate the hair shaft to provide long-lasting color by interacting with the hair's natural proteins. These tints typically contain small dye molecules that can enter the hair cuticle and bond with the keratin, allowing for a more effective and durable color change. Additionally, they can enhance the vibrancy and depth of the hair color while minimizing fading over time. However, they may also lead to potential damage if not used properly, as they can alter the hair’s structure.
