L'Oréal Professionnel Keratin Alpha Sleek Hair Mask 250ml

Product Description

L’Oréal Professionnel’s Keratin Alpha Sleek Hair Mask is a professional smoothing mask designed to help tame frizz, soften and hydrate hair, and support a more controlled, sleek finish. It’s made to work as part of the Keratin Alpha Sleek routine, transforming hair for long-lasting smoothness and frizz & volume control.*

What makes it stand out is the in-fibre approach: the formula is designed with “Keratin-alpha shaper” and amino-acid chains to reshape and smooth the hair’s keratin structure. The brand also claims instant shine, plus measurable results such as 84% less frizz, 74% more shine and 61% more hydration (instrumental tests, after 4 applications as part of the full routine*).

Suitable for all hair types, the mask is used after the Keratin Alpha Sleek shampoo and left on for 5 minutes before rinsing. For best, longer-lasting smoothness, L’Oréal Professionnel recommends using Smooth Transformer once a week and this mask on other wash days.
