L'Oréal Paris Total Repair 5 Repairing Shampoo helps combat the five signs of damaged hair - Hair fall, Dryness, Roughness, Dullness, and Split ends without weighing it down. Damaged hair lacks the natural cement that keeps the hair strong and resilient. To make sure the hair gets the required strength, the L'Oréal Laboratories have included the Keratin XS technology to replicate the hair's natural cement to target the five major problems. The smallest form of Keratin XS deeply penetrates the fibres to ensure faster repair.
