TLDR Keratin helps protect and strengthen hair, reducing damage and color fading.

The study described how keratin actives with unique properties provided various benefits to different hair types. These functional keratins were observed to protect hair from damage caused by chemical treatments like perming and relaxation, help restore the mechanical strength of damaged fibers, and reduce the fading of colored hair.
