L'Oréal Professionnel DUO Keratin Alpha Sleek Shampoo & Smooth Transformer 300ml, 200ml

Product Description

L’Oréal Professionnel’s DUO Keratin Alpha Sleek Shampoo & Smooth Transformer is a salon-style smoothing routine designed to tackle frizz and leave hair looking sleeker and more polished for up to two weeks. The Shampoo helps cleanse while keeping the Keratin Alpha Sleek benefits working after wash, while the Smooth Transformer is the step that focuses on visible smoothing and anti-frizz control. It’s all about making hair feel more disciplined and boosting the look of shine with a neat, glossy finish.

Key benefits include up to 2 weeks of frizz control, 5x more softness and 2x less frizz (claims shown by the brand from tests using the routine), plus styling time that feels quicker. It’s suitable for all hair types, including hair that’s coloured or lightened.

What makes it stand out is the Keratin-Alpha technology with amino-acid chains, described as helping remodel hair at the alpha-keratin level and supporting the hair’s integrity. The Smooth Transformer is free from artificial colourants and alcohol, and it’s designed to be left on for 10–15 minutes, then rinsed.
