Redken Extreme Length Conditioner for Damaged Hair, 10.1 fl oz — Biotin & Castor Oil Strengthening

Redken Extreme Length Conditioner is a biotin- and castor-oil infused conditioner that detangles, fortifies damaged strands, and helps reduce breakage so hair can grow longer and healthier-looking.

Formulated by Redken professionals, this lightweight conditioner is designed to be used as part of the Extreme Length system (with the matching shampoo and leave-in sealer) to reinforce fragile hair from root to tip. The formula combines biotin — a nutrient associated with hair strength — and nourishing castor oil to condition, smooth, and minimize the visible effects of split ends while keeping hair manageable and shiny.

How does this conditioner reduce breakage and support length?

The formula targets weakened areas along the hair shaft to make strands more resilient to everyday stressors like brushing, styling, and environmental wear. With repeated use in the Extreme Length regimen, hair shows fewer breakage points and appears fuller and more continuous in length.

• Contains biotin to support strand strength and structure.
• Castor oil helps nourish and smooth the cuticle for less friction.
• Lightweight conditioning avoids weighing hair down while protecting it.
• Designed to work with Extreme Length Shampoo and Sealer Leave-In for best results.

Will it work for my hair type and texture?

Extreme Length Conditioner is formulated for all hair types and textures, from fine to coarse and straight to curly. The balancing formula provides enough moisture for drier or textured hair without leaving fine hair limp, making it a versatile option for people trying to grow out their hair.

• Safe for color-treated hair when used as directed.
• Suitable for chemically treated or naturally textured hair that needs reinforcement.
• Light enough for daily or regular use depending on your routine.

How should I use this conditioner for the best results?

Apply after shampooing with the matching Extreme Length Shampoo, focusing on mid-lengths to ends where breakage and split ends commonly occur. Rinse thoroughly and follow with the Extreme Length Sealer Leave-In if you want additional protection and extra targeting of split ends.

• Use on wet hair after shampooing; leave for a minute or two for penetration.
• Combine with Extreme Length Shampoo and Sealer Leave-In for optimal reduction in breakage.
• Regular use helps maintain smoother, more manageable lengths over time.

What visible improvements can I expect and when?

Visible changes depend on hair condition and how consistently you use the full system, but many users report reduced breakage and fewer visible split ends with continued use. The product aims to support healthy-looking growth rather than instantly increasing length overnight.

• Reduces appearance of split ends when used with the system.
• Helps hair feel nourished, softer, and easier to detangle.
• Designed to fortify strands so breakage is minimized over weeks to months.

Who is this for: Redken Extreme Length Conditioner is ideal for anyone who struggles to grow hair past a certain point due to snapping, split ends, or breakage. It suits people with damaged, chemically-treated, or naturally textured hair who want a professional-strength conditioner that supports length, reduces breakage, and leaves hair conditioned without heavy buildup. For best outcomes, use it as part of the Extreme Length system recommended by Redken professionals.
