L'Oreal Professionnel Serie Expert Pro Longer Mask helps thicken 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 reduced visibly by 66%.
The Filler A-100 technology works by penetrating the fibre 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.
