Alterna Caviar Repair Rx Instant Recovery Shampoo is a deeply reparative shampoo which reconstruct each individual strand of hair from the inside out to rebuild, resurface and restore hair, leaving strands strong, healthy, smooth, shiny & fully restored. Key product benefits are derived from Strand-Building Proteins, which target damage at the microscopic level, working to repair each individual strand of hair: REBUILDS: This unique ingredient blend delivers essential nutrients to the hair's interior cortex, nourishing to help strengthen strands. Fills in gaps & tears in the damaged cuticle, reconstructing this protective layer to ensure that nutrients do not escape. Cements the newly constructed, exterior cuticle to the interior cortex, ensuring that the scales of the hair lay flat. RESURFACES: Seals and reinforces the cuticle layer with a defensive shield that strengthens the strand to increase resistance to breakage while infusing hair with vital antioxidants to help prevent free radical penetration and other damage from occurring. RESTORES: Leaves strands fully restored to their healthy, pre-damaged state. Hair is stronger, smoother, softer and shinier. Color Holdé: A proprietary color protection complex found in all Alterna products that provides the highest level of color protection from color fade caused by UVA, UVB and visible light rays - including artificial light sources.
