L’Oréal Professionnel Pro Longer Masque restores thickness and strength to long hair in one deep treatment. L'Oréal's Filler A-100 technology penetrates the fibre to reinforce the strand and boost apparent thickness, while rich conditioners moisturise and smooth from mid-lengths to ends.

Benefits
  • Boosts thickness — Filler A-100 reinforces and plumps the fibre.
  • Strengthens — reduces breakage and the look of thinning ends.
  • Deep moisture — silky, frizz-free, easier to detangle.
  • Lightweight — conditions without weighing long hair down.
How to use
  1. After washing, apply to damp hair from mid-lengths to ends.
  2. Leave 3–5 minutes to let the formula penetrate.
  3. Rinse thoroughly; use once or twice a week.
