Keratin Alpha Sleek

The L’Oréal Professionnel Keratin Alpha Sleek range is a professional haircare system designed to deliver long-lasting smoothness & frizz control for all hair types. Read More

Built around advanced hair science, the range targets the internal structure of the hair fibre rather than just coating the surface. At the core of the technology is “Keratin Alpha,” the natural protein that determines hair’s shape, strength, and elasticity. By working at this deep level, the range aims to “reprogramme” hair for sleeker, softer results that last up to two weeks.

The range includes a complete routine: the L'Oréal Professionnel Keratin Alpha Sleek Shampoo, L'Oréal Professionnel Keratin Alpha Sleek Smooth Transformer Treatment 200ml, L'Oréal Professionnel Keratin Alpha Sleek Hair Mask For Anti Frizz & Smoothing 250ml and L'Oréal Professionnel Keratin Alpha Sleek Hair Serum Anti Frizz 50ml.

What makes Keratin Alpha Sleek stand out is its ability to provide salon-like results at home without traditional keratin treatments. Unlike surface-level products, it reshapes the hair fibre internally to control volume and frizz more effectively over time.

If you’re tired of battling frizz, spending too long styling or struggling to achieve that sleek, polished finish, Keratin Alpha Sleek is your solution. Imagine hair that stays smoother for up to two weeks, styles faster every morning, and shines with a healthy, mirror-like gloss.
