L'Oréal Professionnel Serie Expert Liss Unlimited Professional Mask is a rich, smoothing treatment designed for rebellious, frizz-prone hair. The creamy texture coats each strand to help nourish, soften and support a sleeker look that lasts. Enriched with Pro-Keratin and a blend of kukui and evening primrose oils, the formula works to support the hair fibre, helping it feel stronger, smoother and more supple while promoting a healthy-looking shine. Hair is left feeling more disciplined and easier to manage, even in humid conditions.

Ideal for unruly, straightened or frizzy hair types, this mask fits neatly into a weekly or twice-weekly care routine after shampooing. Apply to clean, towel-dried hair, focusing on mid-lengths and ends, and leave for a few minutes before rinsing thoroughly. Used regularly alongside the Liss Unlimited shampoo and finishing products, it helps to support long-lasting smoothness, added gloss and a more polished finish without weighing the hair down.
