Redken Extreme Length Conditioner for Damaged Hair, 33.8 fl oz — Biotin & Castor Oil, Strengthens and Detangles

Redken Extreme Length Conditioner is a strengthening, detangling conditioner with biotin and castor oil designed to reduce breakage and help damaged hair grow longer and healthier.

If your hair stalls in length because of snapping strands and split ends, this salon-formulated conditioner is built to reinforce fragile hair while adding slip, softness, and shine. As part of the Extreme Length regimen (shampoo, conditioner, sealer leave-in), it targets weakened areas along the shaft to improve manageability and support longer-looking hair with fewer interruptions from breakage. The 33.8 fl oz format is sized for regular use at home or in professional settings, ideal for anyone who wants ongoing fortifying care without heavy buildup.

How does this conditioner strengthen hair without weighing it down?

The formula pairs biotin, known for its supportive role in hair fiber health, with castor oil to add conditioning and sheen. Together they deliver lightweight nourishment that smooths and detangles without creating a greasy residue, so hair feels softer and moves naturally.

• Biotin-infused complex to support resilient strands.
• Castor oil for added slip and shine.
• Fast detangling for easier comb-through and reduced mechanical breakage.
• Non-heavy texture suitable for repeated use.

Will this help reduce split ends and visible breakage?

When used consistently alongside the Extreme Length Shampoo and Sealer Leave-In Treatment, the system is designed to reduce visible split ends and minimize breaking points. Conditioning the shaft and improving manageability decreases the friction and stress that cause breakage.

• Conditions the hair surface to lower friction during styling.
• Helps smooth rough fibers that lead to split ends.
• Designed to work as part of a three-step routine for best results.
• Promotes stronger-feeling hair from root to tip.

Is this suitable for my hair type and daily routine?

Yes — the formula is created for all hair types and textures, particularly for people with damaged or fragile hair that resists growing past a certain length. Its lightweight conditioning makes it appropriate for regular, even daily, use depending on your styling needs.

• Safe for straight, wavy, curly, and coily textures.
• Light enough for frequent use without heavy buildup.
• Works well before heat styling to improve smoothness.
• Large size supports consistent at-home maintenance or salon use.

How should I use it for best results?

Apply after shampooing, distribute evenly from mid-lengths to ends, leave on briefly, then rinse. For optimal fortification and visible reduction in breakage, use it as part of the Extreme Length system along with the matching shampoo and the Sealer Leave-In Treatment.

• Use after Extreme Length Shampoo for system benefits.
• Comb through in the shower to detangle and coat strands.
• Rinse thoroughly; follow with Sealer Leave-In for targeted care.
• Use consistently to support long-term improvement.

Who is this for? Redken Extreme Length Conditioner is aimed at anyone who struggles to achieve longer hair because of breakage, split ends, or weakened strands — from salon clients and busy professionals to at-home users who want a professional-strength, easy-to-use conditioner. It fits all textures and is especially helpful for hair that needs reinforcement to grow longer with fewer interruptions. Pair it with the Extreme Length Shampoo and Sealer Leave-In Treatment for the most consistent results in strength and length retention.
