*L’Oréal Professionnel Série Expert Pro Longer Shampoo 300ml & 1500ml

The Pro Longer Shampoo from the Série Expert range by L’Oréal Professionnel is specially designed for long hair with thinning ends. This professional-grade formula addresses the challenge of maintaining length while avoiding look or feel of thinning hair. The patented FILLER-A100 technology plus amino acids work together to renew lengths, plug fibre core, and strengthen ends for a fuller, healthier appearance. 

Key Benefits

• Proven to reduce hair breakage — up to 94% reduction in one test when used with the matching conditioner.  
• Hair appears visibly thicker at the ends and the entire length looks healthier.  
• Boosts shine — up to 5× more visible shine in instrument tests when used as directed.  
• Ideal for hair that’s long with thinning ends or where damage has made ends feel weak. The formula targets these key concerns.  
• Available in professional salon-friendly large size (1500 ml) making it cost-effective for high-volume use.  

How to Use

• Apply to wet hair, massage into lather from roots through lengths to ends.
• Rinse thoroughly.
• For best results, follow with the corresponding Pro Longer Conditioner and optionally the mask or leave-in treatment from the same range.  
• Use regularly as part of a length-maintenance routine.

Why Choose It

Long hair often faces two conflicting issues: maintaining significant length, and preserving the thickness, strength, and appearance of the ends. Many long-hair formulas prioritise length but neglect fibre integrity, leaving ends weak or prone to breaking. Pro Longer directly addresses this by reinforcing the core of the hair fibre (via FILLER-A100) and providing visible improvement in volume and shine. Ideal for salons aiming to deliver premium services to clients with long or frequent-let-grow hair.
