Experience smoother, stronger, and more manageable hair with L'Oréal Professionnel Keratin Alpha Sleek Mask — a deeply nourishing treatment created to control frizz and bring unruly hair back under control.

Powered by advanced keratin technology, this professional-grade mask helps fortify the hair fibre while delivering intense nourishment from root to tip. It smooths the cuticle to minimise flyaways and defend against humidity, leaving hair looking sleek and refined. Perfect for thick, coarse, or frizz-prone hair, its rich, creamy formula penetrates deeply without leaving hair feeling heavy.

From the first application, hair feels noticeably softer, silkier, and easier to style. With regular use, it enhances manageability and boosts shine, helping to maintain a smooth, salon-quality finish. Whether you prefer a straight blow-dry or a polished, glossy look, this mask helps support long-lasting smoothness and improved texture.

Use weekly as an intensive treatment or incorporate it into your regular smoothing routine. L'Oréal Professionnel Keratin Alpha Sleek Mask helps transform dry, resistant hair into soft, sleek lengths with visible, professional results.
