L'Oréal Professionnel Serie Expert Keratin Alpha Sleek Mask 250ml

Discover smoother, stronger, and more manageable hair with L'Oréal Professionnel Keratin Alpha Sleek Mask — an intensive smoothing treatment designed to tame frizz and restore control to unruly hair.

Formulated with advanced Keratin technology, this professional-quality mask helps reinforce the hair fibre while delivering deep nourishment from root to tip. It works to smooth the cuticle layer, reducing flyaways and protecting against humidity, leaving hair visibly sleeker and more polished. Ideal for thick, coarse, or frizz-prone hair, the rich, creamy texture penetrates deeply without weighing hair down.

After just one use, hair feels softer, silkier, and significantly easier to style. With continued use, the formula helps improve manageability and enhances shine, creating a smooth, salon-finish look that lasts. Whether you’re blow-drying straight or embracing a controlled, glossy style, this mask supports long-lasting smoothness and improved texture.

Perfect as a weekly intensive treatment or as part of your regular smoothing routine, L'Oréal Professionnel Keratin Alpha Sleek Mask transforms dry, resistant hair into smooth, touchable soft lengths with professional results you can see and feel.

Achieve sleek perfection and long-lasting control — every wash day.

For instantly smoother hair, use this mask, for long-lasting smoothness, use Smooth Transformer once a week, and use this mask on other wash days of the week. After using Keratin Alpha Sleek professional shampoo, apply evenly from lengths to tips. Leave on for 5 minutes and rinse. In case of contact with eyes, rinse immediately and thoroughly.
