Overview
Not a single jar, this Nexxus pack holds twenty Keraphix masks, each using Keratin Resistance Therapy with serine to rebuild weak bonds. Humectants draw moisture inside the fiber, and a fine film smooths the surface.
Deep bond repair with fast visible results suits hair damaged by color or heat. Directions and leave-on time are missing from the listing.
Who it's for
People with over-processed, rough hair get structural repair and softness. Those with healthy hair may find a protein mask more than they need.
