Redken Extreme CAT Protein Reconstructing Treatment for Distressed Hair — Rinse-Out with Ceramides, Strengthens & Adds Shine

Redken Extreme CAT is a rinse-out protein reconstructing treatment that instantly strengthens distressed, brittle hair while restoring smoothness and shine without weighing strands down.

Designed for hair weakened by heat, chemical services, or everyday breakage, this salon-grade treatment uses Redken's Strength Complex and targeted proteins to rebuild the fiber and reinforce elasticity. It works as a prep step before color or chemical services and fits into a regular care routine to reduce visible damage and improve manageability. The formula focuses on rebuilding internal structure while keeping hair light and soft, rather than coating it with heavy conditioners.

How quickly will I notice stronger hair after using this treatment?

Most users feel improved manageability and a firmer strand texture immediately after rinsing; longer-term improvement in breakage resistance becomes noticeable after several consistent applications. Results depend on hair condition and frequency of use, but the protein-rich formula is designed to give both immediate and progressive benefits.

• Visible smoothing and reduced frizz right after one application
• Progressive reduction in snap and split ends with regular use
• Preps hair for chemical services to limit future damage

Will this treatment weigh my hair down or make it feel stiff?

No — Redken engineered the formula to reconstruct using lightweight proteins and ceramides so hair gains strength without a heavy residue. It reconditions the fiber while maintaining natural movement, so styles remain touchable and flexible rather than stiff or coated.

• Rinse-out design prevents buildup when used as directed
• Ceramides smooth the cuticle for added shine without heaviness
• Suitable for fine to medium hair when applied sparingly

How should I use Extreme CAT for best results and when before salon services?

Use after shampooing: distribute evenly through towel-dried hair, leave on according to directions, then rinse thoroughly. If preparing for a chemical service, apply as part of the pre-service protocol to strengthen vulnerable areas and help the hair tolerate processing better.

• Apply to clean, damp hair focusing on mid-lengths and ends
• Leave in for the recommended time, then rinse completely
• Use weekly or as needed for distressed hair; more often for very damaged hair

What specific benefits does the formula deliver for damaged hair?

Beyond immediate fortification, the treatment reconstructs weakened fiber and reconditions the hair surface to improve shine and combability. The combination of Redken's Strength Complex and ceramides targets structural repair while smoothing the cuticle to reduce friction and breakage.

• Protein rebuilds internal structure to reduce hair breakage
• Ceramides reinforce cuticle adhesion for smoother strands and extra shine
• Lightweight finish prevents limpness while improving manageability

Who is this for: Redken Extreme CAT is intended for people with visibly distressed, brittle, chemically treated, or heat-damaged hair who want a salon-quality reconstructing treatment that strengthens without weight. It works well for those prepping hair before coloring or chemical services and for anyone seeking a weekly intensive reconstructing step. If you have extremely fine hair, use a smaller amount and focus on the mid-lengths and ends to avoid over-conditioning.
