Redken Extreme Cat Rinse Out Treatment

A protein-rich, rinse-out treatment spray that strengthens and reinforces distressed, chemically damaged hair.

What it does:

Redken Extreme CAT Treatment is a lightweight, protein-restructuring spray that helps repair and strengthen hair damaged by colouring, bleaching, and heat styling.

Formulated with Redken’s Strength Complex and proteins, CAT restores internal strength, improves resilience, and preps hair for chemical services.

Unlike masks or conditioners, this treatment delivers targeted protein without added moisture, making it ideal for fragile, over-processed hair that needs a pure protein boost.

Key ingredients:

• Strength Complex with Proteins + Amino Acids – Rebuilds hair structure from within
• Arginine – Supports root-to-tip hair strength
• Lightweight formula – Adds strength without weighing hair down

Who it’s for:

Perfect for highly sensitized, chemically treated, or fragile hair in need of protein rebuilding. Especially recommended before or after chemical services like bleaching or colouring.

How to use:

After shampooing, spray evenly on towel-dried hair. Leave on for 3–5 minutes, then rinse thoroughly. Do not use immediately after a conditioner or mask. Use 1–3 times per week, depending on hair damage.
