L'Oréal Professionnel Série Expert Keratin Alpha Sleek Hair Mask 500ml is a professional smoothing treatment created for salon environments where larger formats are required for frequent use. Developed with Keratin-Alpha shapers and amino-acid chains, this advanced formula works to smooth the hair fibre while improving softness, shine and manageability.

The rich, sensorial mask helps tame frizz-prone hair and reduce unwanted volume, leaving hair feeling noticeably smoother after each treatment. When used as part of the complete Keratin Alpha Sleek routine, it helps reprogramme the hair fibre for up to two weeks of frizz control, making daily styling quicker and more efficient for professionals.
