Give your long hair the care it deserves with the L’Oréal Professionnel Serie Expert Pro Longer Mask, a deeply nourishing and fortifying treatment specially designed to strengthen lengths and reduce the appearance of split ends. Developed for those who love their long locks but struggle with thinning, breakage, or damaged ends, this professional-quality mask helps you maintain length with confidence.

Formulated with Filler-A100—a patented technology exclusive to L’Oréal—and amino acids, this intensive mask penetrates deep into the hair fibre to thicken the ends, reinforce strength, and improve overall hair density. It fills in weak or thinning areas, leaving hair visibly fuller, smoother, and shinier without weighing it down.

Perfect as a weekly treatment or part of your regular hair care routine, the Pro Longer Mask restores vitality to long, tired hair, giving it renewed life from root to tip.

Key Benefits:

• Thickens Hair Lengths & Ends: Instantly fills in and strengthens weakened areas
• Reduces Breakage & Split Ends: Supports hair fibre renewal and resilience
• Deep Conditioning Care: Nourishes and hydrates without heaviness
• Smooth, Shiny Finish: Leaves hair soft, glossy, and easy to manage
