Redken Extreme Length Shampoo for Damaged Hair — 10.1 fl oz | Biotin Strengthens & Reduces Breakage

Redken Extreme Length Shampoo is a biotin-enriched strengthening cleanser designed to fortify fragile, damaged hair and help reduce breakage so strands can grow longer.

This shampoo gently cleanses while delivering fortifying ingredients from root to tip. Formulated with biotin and Redken's Length Care Complex, it targets weak spots along the hair shaft to help minimize breakage and improve the appearance of split ends when used as part of the full Extreme Length system. The 10.1 fl oz size is suitable for regular at-home use and for anyone building a routine focused on healthier, longer-looking hair.

How does this shampoo help hair grow longer?

The formula focuses on strengthening existing strands so they resist breakage, which allows hair to retain length over time. Rather than speeding biological growth, it reduces the loss of length caused by fragile, damaged ends and weakened fibers.

• Contains biotin to help fortify weakened hair fibers.
• Length Care Complex helps reinforce strands from root to tip.
• Gentle cleansing preserves moisture while removing buildup that can stress hair.

Will it reduce split ends and breakage?

Regular use can improve the look and resilience of hair, decreasing visible split ends and breakage when combined with the matching conditioner and leave-in sealer. The product is formulated to smooth and strengthen the hair surface to better withstand daily wear.

• Targets weak points that commonly lead to breakage.
• Helps reduce the appearance of split ends with consistent use.
• Works best as a system with Extreme Length Conditioner and Sealer for full benefits.

Is this suitable for my hair type?

Redken Extreme Length Shampoo is formulated to be effective across hair types and textures, particularly for hair that is fragile, damaged, chemically treated, or prone to breakage. It cleanses without over-stripping, making it appropriate for regular routines.

• Safe for color-treated and chemically processed hair.
• Recommended for fine to medium textures that need strengthening.
• Can be used on curly and straight hair as part of a length-care regimen.

How should I use it for best results?

Massage into wet hair, focusing on roots to ends, then rinse thoroughly; follow with Extreme Length Conditioner and use the Sealer leave-in treatment to lock benefits in. Consistent, system-based use maximizes visible improvements in strength and split-end control.

• Apply to wet hair, lather gently, rinse and repeat if needed.
• Pair with Extreme Length Conditioner and Sealer for optimal outcomes.
• Use regularly—weekly routines deliver the most consistent improvement.

Who is this for: Redken Extreme Length Shampoo is aimed at anyone seeking stronger, longer-looking hair—especially people with damaged, fragile, or breakage-prone hair who want to preserve and build length without harsh stripping. It suits salon-minded users who prefer professional-grade formulations and those who plan to use a coordinated system for visible length-care results.
