Redken Extreme Hair Mask for Damaged Hair, 8.5 fl oz — Strengthens & Smooths

Redken Extreme Hair Mask is an intensive rinse-out treatment that fortifies dry, brittle hair with protein and lactic acid to increase strength and smoothness for up to three washes.

Designed for hair weakened by chemical services, heat styling, or mechanical stress, this rich conditioning mask uses Redken's Strength Complex to rebuild and reinforce strands. The formula combines proteins, amino acids and citric acid to help restore structural integrity, balance pH and reduce friction that leads to breakage. Use weekly or as needed to improve manageability, shine and resilience between salon-strengthening treatments.

How does this mask rebuild weak or damaged hair?

The mask delivers concentrated building blocks—proteins and amino acids—that temporarily bond to compromised areas of the hair shaft, helping to reinforce fragile points. Lactic acid helps condition and smooth the cuticle so strands lie flatter and reflect light better. Results include reduced breakage during brushing and improved wet-to-dry handling.

• Strength Complex with protein and amino acids targets weakened fiber.
• Lactic acid helps smooth cuticle and balance hair surface pH.
• Formulated to treat root, core and tip for uniform reinforcement.

When should I use the Redken Extreme Mask in my routine?

Use this rinse-out mask 1–2 times per week for maintenance or more frequently if hair is highly compromised. Apply after shampooing to clean, towel-dried hair, leave on for the recommended time, then rinse thoroughly. It complements daily conditioners and leaves-on treatments rather than replacing professional salon services when needed.

• Apply after shampoo on damp hair for 5–15 minutes depending on damage level.
• Rinse fully and follow with styling products as usual.
• Use weekly for upkeep or more often for intensive repair cycles.

What visible benefits can I expect and how long do they last?

Immediately, hair feels softer and smoother with reduced friction during combing. The mask’s fortifying effect is designed to persist through daily washes—Redken notes benefits lasting up to three shampoos, depending on hair porosity and routine. With consistent use, split ends and breakage become more manageable and overall hair resilience improves.

• Instant smoothing and detangling for easier styling.
• Strength boost that can last through multiple washes.
• Progressive reduction in breakage and improved shine with repeated use.

How do ingredients like arginine and citric acid contribute?

Arginine and other amino acids support the hair’s protein network, helping refill weakened areas and add elasticity. Citric acid helps refine the cuticle surface and balance pH to lock in smoothness and shine. Together they work with soy-derived proteins in Redken’s Strength Complex to address both internal structure and external texture.

• Arginine and amino acids reinforce internal fiber strength.
• Citric acid smooths cuticle and stabilizes hair surface pH.
• Soy protein components help rebuild and bulk up fragile strands.

Who is this for: Redken Extreme Hair Mask is formulated for anyone with dry, chemically processed, heat-damaged or brittle hair seeking an in-shower strengthening treatment. It’s suitable for color-treated and textured hair types that need targeted reinforcement rather than lightweight daily conditioning. Choose this mask if you want an intensive regimen-level conditioner to reduce breakage, smooth the cuticle, and restore manageability between salon visits.
