What it is

A professional keratin-based shampoo with an ultra-rich creamy texture. The sulfate-free formula gently cleanses, respecting the hair fiber and strengthening the hair's keratin structure. It is the first step in the complete Keratin Alpha Sleek routine.

Key Benefits

Ingredients and technology

The formula contains Keratin-Alpha shaper, a complex that reshapes the keratin structure, and amino acid chains that penetrate the fiber to strengthen it from within. The creamy sulfate-free texture respects the natural pH of the scalp.

How to use

Apply to wet hair, distributing evenly from roots to ends. Massage until a rich lather forms. Rinse thoroughly. For optimal results, follow once a week with the Smooth Transformer.
