Dr. C. Tuna Intensive Repair Hair Mask

The Dr. C. Tuna Intensive Repair Hair Mask is a professional-strength treatment for severely damaged, over-processed, or heat-stressed hair. Its concentrated formula delivers an intensive dose of reparative actives directly into the hair shaft — visibly reducing split ends, breakage, and porosity over time. For best results, use weekly as the final step of the Intensive Repair routine before rinsing.
