L'Oréal Paris Total Repair 5 Restoring Conditioner excels at addressing the five visible indicators of damaged hair: hair loss, dryness, roughness, dullness, and split ends. Damaged hair sometimes lacks the natural cement required to make the hair strong and resilient. The L'Oréal team has combined the Keratin XS technology to compensate the hair with natural cement to ensure cohesiveness and strength. Keratin XS technology penetrates the core layer of the fibers, allowing for quicker repair.
