L'Oreal Professionnel's Pro Longer mask 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. Amino acids in the formula work to strengthen the hair from the outside. The formula works on thin ends, or areas where help is most needed.
