Redken Extreme Length Conditioner is a biotin- and castor oil–infused conditioner designed to fortify damaged hair, reduce breakage, and help strands grow longer when used as part of the Extreme Length system.

This lightweight conditioner combines biotin and castor oil to nourish and strengthen hair from root to tip. Formulated for those trying to grow past breakage points, it detangles, smooths, and helps minimize the appearance of split ends while leaving hair manageable and shiny. Use it alongside Redken Extreme Length Shampoo and the Sealer Leave-In Treatment for the full system benefits.

How does Extreme Length Conditioner strengthen fragile or damaged hair?

The formula targets weak areas along the hair shaft with fortifying ingredients like biotin and castor oil that help reinforce strands and reduce mechanical breakage. Conditioning agents smooth the cuticle, making hair less prone to snapping during brushing and styling.

• Biotin supports visible hair strength and resilience.
• Castor oil nourishes and helps improve strand flexibility.
• Light conditioning reduces tangles and friction during detangling.
• Recommended use as part of the Extreme Length system for best results.

Will this conditioner help reduce split ends and breakage?

When used together with Extreme Length Shampoo and the Sealer Leave-In Treatment, the system has been shown to significantly reduce breakage and the visible look of split ends. The conditioner itself provides smoothing and reinforcement to help hair endure daily styling and handling.

• System use reported up to 81% less breakage.*
• Visible split ends reduced when the full system is used.
• Leaves hair conditioned and easier to comb through.
• Suitable for repeat use to maintain improved strand integrity.

Is this suitable for my hair type and how does it feel on hair?

Extreme Length Conditioner is formulated to work across hair types and textures, particularly for hair that struggles to get past breakage-prone lengths. It delivers lightweight nourishment so hair feels conditioned without excess weight or residue.

• Works on straight, wavy, curly, and coily hair textures.
• Provides detangling benefits without heavy buildup.
• Helps maintain shine and manageability after rinsing.
• Safe for regular use as part of a length-focused routine.

How should I use this conditioner for best results?

After shampooing with Extreme Length Shampoo, apply an even amount of conditioner from mid-lengths to ends, leave on briefly, then rinse thoroughly. For optimal improvement in breakage and split ends, add the Sealer Leave-In Treatment to your routine as directed.

• Use after Extreme Length Shampoo for system benefits.
• Concentrate on mid-lengths and ends; avoid heavy roots if you are fine-haired.
• Rinse well and follow with Sealer Leave-In Treatment for long-term results.
• 10.1 fl oz size supports many applications for routine use.
