Redken Extreme Length Shampoo for Damaged Hair — 10.1 fl oz Biotin Strengthening, Prevents Breakage

Redken Extreme Length Shampoo is a biotin-enriched strengthening shampoo that gently cleanses while helping fortify fragile, damaged hair from root to tip to support longer, stronger strands.

Designed by Redken, a professional salon brand, this 10.1 fl oz formula combines cleansing agents with a Length Care Complex and biotin to target the common causes of breakage. When used as part of the Extreme Length system (shampoo, conditioner and sealer), Redken reports measurable improvements in breakage reduction and the visible appearance of split ends, supporting healthier-looking hair so it can grow longer.

How does this shampoo reduce breakage and support length?

The formula uses biotin, a nutrient often chosen to fortify strands, together with Redken's Length Care Complex to strengthen weak areas along the hair shaft. It gently removes dirt and buildup while leaving hair easier to detangle and less prone to snapping during styling.

• Biotin helps fortify hair structure for improved resilience.
• Length Care Complex targets fragile points from root to tip.
• Gentle cleansing minimizes mechanical stress during shampooing.
• Best results when paired with the matching conditioner and sealer.

Will it help reduce the appearance of split ends?

Used alone this shampoo helps strengthen strands and smooth the hair surface, which can reduce the visible look of split ends. In Redken’s in-house system testing, combining Extreme Length Shampoo, Conditioner and Sealer led to a noticeable reduction in the appearance of split ends versus a non-conditioning shampoo.

• Improves manageability so split ends are less conspicuous.
• System use (shampoo + conditioner + sealer) reported better visual results.
• Regular use supports a healthier length profile over time.

Is this suitable for my hair type and daily routine?

Extreme Length Shampoo is formulated for all hair types but is especially helpful for hair that is fragile, damaged or prone to breakage. Its gentle lather fits into most washing schedules; for best outcomes, follow with the Extreme Length Conditioner and leave-in Sealer to protect and lock in strength.

• Safe for color-treated and chemically processed hair when used as directed.
• Light cleansing suitable for frequent use depending on personal needs.
• Complements professional salon services and at-home care routines.

What results can I expect and how soon?

Individual results vary, but when used consistently as a complete Extreme Length system, Redken testing showed improvements in breakage and split end appearance versus a non-conditioning shampoo. Typical benefits include stronger-feeling strands, easier detangling and a smoother look along the hair shaft.

• Progressive strengthening with regular system use over weeks to months.
• Improved detangling and reduced mechanical breakage during styling.
• Reported system benefits documented in Redken’s internal evaluations.

Who is this for: Redken Extreme Length Shampoo is ideal for anyone struggling to grow hair longer because of fragility, breakage or visible split ends. It suits all textures and lengths, particularly hair that has been weakened by heat, color or chemical processes and needs targeted root-to-tip strengthening as part of a consistent care routine.
