L'Oreal Professionnel's Pro Longer concentrate treatment thickens long hair for visibly healthier and stronger looking lengths. ​When used with the Pro Longer shampoo and ends-filler treatment for long hair, split ends are visibly reduced. ​The unique Filler A-100 technology works by penetrating the fiber core to plump and thicken the hair from the inside.
