L'Oreal Keratin Alpha Sleek Progressive Treatment 200ml

The L’Oréal Professionnel Keratin Alpha Sleek Progressive Treatment 200ml is a professional weekly smoothing treatment designed to progressively transform hair for long-lasting smoothness, frizz control and volume control.

Formulated with Keratin Alpha Shaper and amino-acid chains, this intensive treatment works progressively, with performance peaking after four weekly applications. The result is up to 5x smoother hair, 2x less frizz and +77% instant shine, while helping preserve hair integrity.

Designed for all hair types, the treatment helps discipline difficult-to-manage hair and significantly simplify everyday styling. When used as part of the complete Keratin Alpha Sleek routine, daily styling can take half the time, with smoothing results lasting for up to 2 weeks.

For best results, use once weekly after shampooing, leave on for 10–15 minutes and rinse. Follow with the Keratin Alpha Sleek Serum, then completely blow-dry and straighten the hair to activate the smoothing technology.
