L'Oréal Professionnel Série Expert Keratin Alpha Sleek Professional Mirror Sleek Serum 50ml controls frizz and smooths hair for up to 10 washes.

Product Description

L'Oréal Professionnel Série Expert Keratin Alpha Sleek Professional Mirror Sleek Serum 50ml is a leave-in hair serum that delivers lasting smoothness and controlled frizz and volume. Its formula contains 5% of a Keratin Sealant, which, when activated by heat, seals the hair's keratin structure from within. In fact, it works at the level of Alpha-Keratin to reshape the fiber and target frizz and volume at the source. The result is smoothness and frizz control that lasts up to 10 washes when the complete routine is used. Beyond that, the formula controls frizz in up to 80% humidity, so results hold even in challenging conditions.

Furthermore, this serum provides thermal protection up to 230°C, and it reduces styling time by half. All in all, this serum delivers smooth, frizz-controlled results for softer, sleeker hair that stays that way.
