PRO LONGER concentrate from L'Oréal Professionnel , a single-dose tip filler concentrate.
This concentrated treatment is ideal for long hair with fine tips that suffer from breakage and split ends.
Thanks to the high concentration in the patented FILLER-A100 molecule and amino acids, this professional formula provides strength and lasting thickness immediately. These components penetrate the core of the fiber to thicken the ends and re-emerge the lengths.
