Original Unused/Unopened Split End Correction Formula. 12 oz. bottle with Pump. Split End Correction is a dual service innovation that can be used to instantly seal splits/tears or, used as a cutting lotion to preserve the shape of precision cuts for up to 4 weeks. Utilizing a bio reparative complex, Split End Correction rebuilds and fortifies weakened fibers, helping defend against cuticle cracking to prevent tears before they start. A proprietary Thermo-Marine Bonding System™ fills in and helps bind broken fibers together, instantly mending split ends. This creates a smooth surface area, reducing friction so blades glide more easily through the hair to optimize precision and keep cuts looking sharp between appointments. Future breakage is dramatically reduced as a protective heat activated coating surrounds each strand, defending against mechanical damage and hot tool styling.
