Redken Extreme Length Strengthening Conditioner, 33.8 fl oz — Biotin & Castor Oil to Reduce Breakage

Redken Extreme Length Conditioner is a strengthening, detangling conditioner with biotin and castor oil designed to reduce breakage and support longer, healthier-looking hair.

Made for hair that stalls in length because of breakage, this salon-formulated conditioner pairs with the Extreme Length system to fortify strands from root to tip. Lightweight yet nourishing, it smooths cuticles, helps reduce the appearance of split ends, and leaves hair easier to comb and shinier after use. The 33.8 fl oz size is ideal for at-home maintenance or for stylists keeping a professional station stocked.

How does this conditioner strengthen hair without weighing it down?

The formula combines biotin, known for supporting resilient hair structure, with castor oil, which helps smooth and condition the strand surface. Together they deliver focused nourishment that reinforces weak points without leaving a heavy residue, so even finer textures feel clean and manageable.

• Biotin-enriched formula to support stronger strands
• Castor oil for slip and surface conditioning
• Light, non-greasy finish suitable for frequent use
• Helps improve wet combability to limit mechanical breakage

Will it actually help my hair grow longer?

The conditioner is designed to reduce breakage—the main reason hair appears not to grow—by strengthening and protecting the shaft. When used with Redken Extreme Length Shampoo and Sealer leave-in treatment, users can expect improved retention of existing length so hair can reach its growth potential.

• Part of a three-step Extreme Length system for best results
• Formulation targets breakage to improve length retention
• Visible reduction in split ends when used as a system
• Supports healthy-looking strands from root to tip

Is this conditioner right for my hair type and damaged ends?

Extreme Length Conditioner is formulated for all hair types and textures, particularly those with damage that prevents length retention. It provides lightweight nourishment that smooths and helps protect vulnerable ends, making it a practical daily or regular-use conditioner for damaged or frequently styled hair.

• Suitable for fine through coarse textures
• Works on chemically treated and heat-styled hair
• Helps reduce split-end appearance by smoothing the cuticle
• Safe to use with other Redken color and care products

How should I use it for best results?

Apply after shampooing, focusing on mid-lengths to ends, and leave on briefly to allow the active ingredients to penetrate. Rinse thoroughly and follow with the Sealer leave-in treatment or your preferred finishing products to protect newly strengthened strands.

• Use with Extreme Length Shampoo and Sealer for optimal benefit
• Massage into damp hair, comb through, then rinse
• Can be used regularly; adjust frequency based on dryness and styling
• Follow with heat protection if you blow-dry or style

Who this is for: Redken Extreme Length Conditioner is aimed at anyone who wants to reduce breakage and reveal longer, healthier-looking hair—especially people with damaged, chemically treated, or frequently styled hair. It suits salon professionals and consumers who prefer science-backed haircare and need a generous-sized conditioner for consistent use. If your hair tangles easily, shows split ends, or stalls in length, this conditioner can be a practical step in a routine focused on retention and visible strength.
