L'Oréal Professionnel Série Expert Keratin Alpha Sleek Shampoo 1500ml is a professional sulfate-free shampoo designed for salon backwash services, helping stylists smooth, strengthen and control frizz-prone hair during cleansing. Formulated with Keratin Sleeker technology and amino-acid chains, this advanced professional shampoo gently purifies the hair fibre while reinforcing keratin to improve manageability, softness and shine.

Its luxurious ultra-creamy texture works to reshape the hair’s keratin structure and reduce unwanted volume, allowing hairdressers and stylists to create sleek, controlled looks more efficiently during professional services. When used as part of the full Keratin Alpha Sleek routine, the system helps reprogramme hair for up to two weeks of frizz control while maintaining smoothness and shine.
