Pro Longer Mask 250mL

Pro Longer Mask for Longer, Thicker Hair

Want to give your long hair a boost? The L'Oréal Professionnel's Pro Longer mask is formulated to strengthen and thicken your hair, giving you visibly healthier and stronger lengths. When used with the Pro Longer shampoo and ends-filler treatment, it can reduce the appearance of split ends by 66%.

This unique formula uses a powerful combination of technologies. Filler A-100 works by penetrating the hair's core to plump and thicken the hair from the inside out. At the same time, amino acids strengthen the hair from the outside. The result is hair that looks and feels thicker and healthier, especially in areas where it's needed most.
