L’Oréal Professionnel Serie Expert Keratin Alpha Sleek Shampoo 1500ml

L'Oréal Professionnel Keratin Alpha Sleek Shampoo is carefully crafted to smooth, protect, and refine unruly hair, leaving it sleek and polished. Ideal for frizz-prone or chemically treated hair, this salon-quality formula gently cleanses while helping preserve the effects of keratin and smoothing treatments.

Infused with advanced smoothing technology, it helps tame flyaways, reduce excess volume, and improve manageability from the very first wash. The lightweight yet nourishing formula works to strengthen the hair fibre, leaving strands soft, flexible, and easier to style. By sealing the cuticle and shielding against humidity, it promotes lasting smoothness and shine without weighing the hair down.

Perfect for achieving professional results at home, Keratin Alpha Sleek Shampoo helps prolong the benefits of straightening treatments while restoring a silky, glossy finish. Hair feels smoother, appears healthier, and stays more resistant to frizz throughout the day.
