The L'Oréal Professionnel Keratin Alpha Sleek Hair Mask Anti Frizz & Smoothing 250ml is a nourishing treatment designed to smooth and soften the hair after cleansing. Featuring a sumptuously rich texture, the formula coats the lengths with conditioning nourishment while helping to support the strands for a sleeker feel. Applied after shampoo and left for five minutes, the mask helps reduce the appearance of flyaways, while leaving hair feeling hydrated and easier to manage. The result is hair that appears smoother and glossier without feeling weighed down.
