Unruly, rebellious hair usually starts reacting to humidity within hours of leaving the shower, undoing a fresh blow-dry almost immediately. L'Oreal Professionnel Serie Expert Liss Unlimited Hair Mask is built to hold that line: Pro-Keratin works to reinforce and hydrate the hair fiber, while Kukui and Evening Primrose oils create a humidity barrier that keeps strands smooth and aligned for up to 4 days, even at 80% humidity.

Best For:
Rebellious, unruly, or frizz-prone hair.
Key Benefits of L'Oreal Professionnel Serie Expert Liss Unlimited Hair Mask 250ml:
  • Provides up to 4 days of anti-frizz effect, even in 80% humidity
  • Deeply nourishes and hydrates the hair fiber while polishing the hair's surface
  • Strengthens hair structure with Pro-Keratin for softer, shinier results
  • Helps discipline unruly, rebellious hair for longer-lasting smoothness
  • Enhances shine and control with continued use
Active Ingredients & How They Work:
  • Pro-Keratin: a blend of amino acids, oils, and keratin that reinforces the hair cuticle, keeping the fiber hydrated and structurally strong.
  • Xylose: a heat-protective sugar that attaches to the hair fiber, helping disperse heat and retain moisture.
  • Oenothera Biennis (Evening Primrose) Oil: rich in essential fatty acids that promote strength and softness in the hair strands.
  • Kukui Nut Oil: works as an anti-humidity barrier on the hair fiber, keeping strands aligned and frizz-free for longer.
