Pro Longer Concentrate Treatment
L'Oréal Professionnel Pro Longer Concentrate is a powerful hair treatment for long hair with weak and thin ends. It is particularly suitable for those who want to grow their hair longer and thicker without the need for regular hair trims. The professional formula contains the exclusive and patented FILLER A-100 and Amino Acids. On one hand, the FILLER A-100 will improve the hair from the inside by penetrating the fiber core and thickening the ends. On the other hand, Amino Acids will strengthen the hair from the outside while preventing breakage.
