Without weighting it down, L'Oréal Paris Total Repair 5 Repairing Shampoo combats the five indications of damaged hair: hair fall, dryness, roughness, dullness, and split ends. Damaged hair lacks the natural cement that holds the hair together and keeps it strong. L'Oréal Laboratories has integrated the Keratin XS technology to recreate the hair's natural cement to treat the five key concerns, ensuring that the hair receives the necessary strength. Keratin XS in its tiniest form deeply penetrates the fibers to allow quicker mending.
