What it is
COSME DECORTE AQ Repair Smooth Treatment Conditioner feels like the kind of step you look forward to at the end of a long day. The creamy texture coats each strand without heaviness, making hair feel instantly softer when you rinse. Used after shampoo, it helps reduce roughness, smooth lifted cuticles, and bring back that glossy, well-kept finish you see in Japanese salon hair. Over time, the surface looks more even, less frizzy, and easier to style—especially on mornings when you want your hair to behave with minimal effort.
Ingredients
(1) Botanical oils: boost softness and slip
(2) Conditioning agents: smooth hair surface
(3) Moisturizing extracts: support hydrated feel
(4) Light-reflecting elements: enhance shine
How to use
After shampooing, apply COSME DECORTE AQ Repair Smooth Treatment Conditioner to the mid-lengths and ends. Comb through with fingers, leave for a short moment, then rinse thoroughly. For extra smoothness, focus on the driest areas and let it sit slightly longer before rinsing.
