Pro Longer

The first professional routine that thickens the ends and strengthens the lengths. Ideal for long, fine or thinning hair.

Pro Longer is the iconic line of L’Oréal Professionnel designed for those who want longer hair that is healthier, stronger and fuller to the ends. Thanks to the exclusive technology FILLER-A100 and Glicoammina, each product works deeply to plump thinning ends, prevent breakage and keep the hair fiber compact and full-bodied.

All products in the collection are tested in our Celebre salons, on real clients with weakened lengths, to guarantee visible efficacy and professional results at home.

🧬 How does Pro Longer work?

🔹 FILLER-A100: patented molecule that penetrates the fiber to plump and rebuild the thinnest areas
🔹 Glicoammina: purifies the fiber from metallic residues and protects the hair structure
🔹 Visible results from the first applications: thicker, stronger and more uniform hair from root to tip
