L'Oreal Professionnel Série Expert Keratin Alpha Sleek

Activate long-lasting smoothness with frizz and unwanted volume control for up to 2 weeks.

L'Oréal Professionnel Série Expert Keratin Alpha Sleek is a** professional smoothing care range for all hair types**. Developed in collaboration with stylists, this range is designed for those who want to reduce frizz, improve smoothness, and keep hair softer, sleeker, and more manageable for longer.

Despite its name, the range does not contain keratin. It uses Keratin Alpha Sleek technology, which works deep within the hair fibre at the Keratin Alpha level to help achieve a smoother-looking finish, control frizz and excess volume, and make everyday styling easier. When used as part of the recommended routine, it can deliver up to 2 weeks of smooth hair with control over frizz and unwanted volume.

The range includes a sulfate-free shampoo, a mask, Smooth Transformer smoothing care, and a serum, which work together to support long-lasting smoothness, shine, and a more disciplined hair look.

The result is smooth, soft, and shinier hair with long-lasting control of frizz and volume, and a professionally sleek finish.
