The Pro Longer family from L'Oreal Serie Expert is the perfect treatment for hair suffering from thinned ends.
Powered by FILLER-A100 and Amino Acid, the Serie Expert Pro Longer Ends Filler Concentrate is the go-to treatment for long hair suffering from thinned ends. Thanks to the high concentration of the patented FILLER-A100 molecule, this disruptive professional formula instantly provides strength and durable thickness to ends.
Visibly reduces split ends by 66% ( according to an instrumental test using shampoo, conditioner and the ends filler concentrate) and the hair feels and looks thicker and more plump from the very first application.
The Filler A-100 technology used is patented to L'Oréal Professionnel, and it 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.
