L'Oréal Professionnel Pro Longer Ends Filler Concentrate 400ml

L'Oréal Professionnel Pro Longer Ends Filler Concentrate 400ml is an intensive professional treatment developed for long hair with thin, weakened and damaged ends.

Powered by patented FILLER-A100 technology and Amino Acid, this concentrated treatment penetrates the hair fibre to help visibly fill and thicken thinning ends, while strengthening weakened areas and improving the overall appearance of long hair. L'Oréal Professionnel specifically positions the treatment for long hair suffering from thinned ends and reports immediate filling from the first application with cumulative results over continued use.

Fill → Thicken Ends → Strengthen → Reduce Breakage → Improve Lengths

What Is It?

Pro Longer Ends Filler Concentrate is a targeted intensive treatment for thinning ends within the L'Oréal Professionnel Pro Longer range.

Rather than functioning as a standard conditioner or mask, its concentrated formula specifically targets the ends of long hair, where thinning, breakage and splitting are often most visible.

Its main positioning is:

Long Hair + Thinning Ends + Split Ends + Strengthening + Thicker-Looking Ends
