The L'Oréal Professionnel Serie Expert Pro Longer Mask, powered by FILLER-A100 and amino acids, is designed to renew and strengthen the lengths and ends of long hair, giving it a fuller, shinier appearance.
The L'Oréal Pro Longer Mask is a targeted treatment for long hair prone to thinning at the ends. It utilizes FILLER-A100, a patented technology that penetrates the hair fiber core to thicken and resurface ends, combined with amino acids to add strength and resilience. This mask is particularly effective in reducing split ends—up to 66% when used as part of a full regimen including Pro Longer shampoo and, for an intensive treatment, the Ends Filler Concentrate.
To use the Pro Longer Mask, apply it to freshly shampooed hair, focusing on the lengths and ends. Leave it on for 3-5 minutes before rinsing thoroughly. For optimal results, use the mask once or twice a week and alternate weekly with the Pro Longer Ends Filler Concentrate for a more intensive, lasting effect on end thickness
