L’Oréal Professionnel Série Expert Pro Longer Conditioner 250ml & 750ml

If you’re managing long hair that may be thinning at the ends or looking less full in the lengths, the Pro Longer Conditioner from the Série Expert range by L’Oréal Professionnel is a targeted solution. Powered by patented FILLER-A100 technology plus amino acids, this conditioner helps renew lengths, strengthen ends and make hair look visibly thicker, healthier and more resilient. 

Key Benefits

• Helps reduce hair breakage: up to ~94% reduction in breakage (when used with the corresponding shampoo) in instrument or brushing tests.  
• Promotes up to 5× shinier hair (instrumental test) when used as part of the Pro Longer system.  
• Specifically formulated for long hair with thinning ends: lengths that may have lost fullness or strength.  
• Smooths, conditions and strengthens the fibre from within (FILLER-A100 penetrates the fibre core; amino acids fortify the structure) to leave hair looking healthier, stronger and better-looking.  

How to Use

After cleansing with your shampoo (preferably the matching Pro Longer Shampoo), apply the conditioner to towel-dried hair, focusing on mid-lengths to ends. Comb through if needed, leave for 1-2 minutes (or slightly longer for more intense conditioning), then rinse thoroughly. For best results, use regularly as part of your long-hair maintenance routine. 

Why Choose It

Long hair can face a unique combination of challenges: maintaining length while keeping ends from thinning, resist breakage, and preserve shine and fullness. Many conditioners treat damage broadly, but the Pro Longer range specifically addresses this by reinforcing the fibre core (via FILLER-A100) and delivering visible improvements in thickness, strength and appearance of the entire length and ends. For salons or retail clients who want premium performance for long hair, this is a strong choice.
