Long hair often thins out toward the ends over time, leaving lengths looking fragile and prone to splitting no matter how carefully they're handled. L'Oreal Professionnel Serie Expert Pro Longer Mask targets this directly: patented Filler A-100 technology penetrates the fiber core to plump and thicken hair from within, while amino acids reinforce strength from the outside.

Best For:
Long, thin hair with weak or splitting ends.
Key Benefits of L'Oreal Professionnel Serie Expert Pro Longer Mask 250ml:
  • Thickens the appearance of long hair for visibly healthier, stronger-looking lengths
  • Visibly reduces split ends by up to 66% when used with the Pro Longer Shampoo and ends-filler treatment
  • Filler A-100 technology plumps and thickens hair fiber from the inside
  • Amino acids strengthen and protect hair from the outside
  • Targets thin ends and other areas that need extra reinforcement
Active Ingredients & How They Work:
  • Filler A-100 (patented technology): penetrates deep into the hair fiber's core, plumping and thickening hair from within to improve the look of thin, fragile lengths.
  • Arginine: an amino acid and natural building block of hair keratin that helps strengthen the fiber and improve manageability.
  • Amodimethicone: a conditioning silicone that smooths the hair surface, adding shine and softness.
  • Panthenol (Pro-Vitamin B5): helps hydrate the hair and support overall fiber health.
