Redken Extreme CAT Protein Reconstructing Treatment for Distressed Hair — 250ml Strengthens & Adds Shine

Redken Extreme CAT is a rinse-out protein reconstructing treatment that immediately strengthens distressed, brittle hair while rebuilding fiber without weighing strands down.

Built on Redken's Strength Complex and formulated for chemically or mechanically damaged hair, this salon-grade treatment delivers protein where hair needs it most. Use it between salon services or after at-home stressors like heat styling to reinforce weakened areas, reduce breakage risk, and restore a smoother surface and visible shine.

How quickly will I notice stronger hair?

Most users feel increased firmness and less breakage after the first application, with cumulative improvements over repeated uses. The formula deposits reparative protein along the shaft to fortify fragile sections immediately while ongoing use helps hair resist future damage.

• Rinse-out treatment delivers immediate tactile strength
• Protein reconstructs weakened fiber to reduce snapping
• Visible manageability and smoother strands after one use

Will this treatment make my hair heavy or greasy?

No — Redken Extreme CAT is designed to rebuild and recondition without adding unwanted weight. The lightweight reconstructing system targets damaged zones and rinses clean, leaving body intact and hair ready for styling.

• Rinse-out texture avoids residue buildup
• Reconditions while preserving natural movement
• Safe to use before chemical services for prep without heaviness

Can it help hair that’s been dyed, bleached, or heat-styled?

Yes — the treatment supports chemically treated and heat-stressed hair by reinforcing weakened cuticle and cortex areas. It works as a supportive reconstructing step to help hair withstand the mechanical and chemical stresses of color, bleach, and frequent heat styling.

• Preps hair before color or chemical services
• Strengthens strands after bleaching or frequent styling
• Helps reduce future breakage during processing

How do I use Extreme CAT for best results?

Apply to clean, towel-dried hair, focusing on mid-lengths and ends where damage is most visible. Leave according to directions, then rinse thoroughly; use weekly or as recommended by your stylist to maintain improved strength and smoothness.

• Use after shampoo on damp hair for optimal absorption
• Concentrate on fragile, distressed sections
• Rinse fully to keep hair lightweight and ready to style

Who is this for? Ideal for anyone with brittle, chemically-processed, heat-damaged, or mechanically stressed hair who wants a professional-strength, rinse-out reconstructing treatment. If you’re seeking immediate reinforcement, reduced breakage, and added shine without weight, Redken Extreme CAT is formulated to rebuild hair structure and improve manageability between salon visits.
