Redken Extreme Length Shampoo — 10.1 fl oz Biotin Strengthening Cleanser for Damaged, Breakage-Prone Hair

Redken Extreme Length Shampoo is a biotin-enriched strengthening cleanser designed to fortify fragile, damaged hair so it can grow longer with reduced breakage.

Formulated by a professional salon brand, this 10.1 fl oz shampoo gently cleanses while delivering ingredients that support stronger strands from root to tip. It’s built around Redken's Length Care Complex and biotin to target weak points along the hair shaft and help reduce the visible signs of split ends when used as part of the full Extreme Length regimen. The texture lathers easily, rinses clean, and pairs with the matching conditioner and sealer for best results.

How does this shampoo help hair that breaks easily?

The formula focuses on strengthening compromised areas of the hair fiber so strands resist snapping during brushing and styling. Biotin works with Redken’s strengthening complex to reinforce structure along the length of the hair rather than just coating the surface.

• Biotin-infused cleanser that supports internal strand strength
• Length Care Complex targets vulnerable root-to-tip zones
• Gentle surfactants that clean without over-drying
• Designed to reduce breakage when used regularly

Can this shampoo reduce the appearance of split ends?

Regular use helps improve hair resilience and smooth the look of the ends, making splits less obvious. While a shampoo cannot permanently repair existing splits, it helps prevent new splitting by strengthening and protecting fragile lengths.

• Helps make ends look healthier and less frayed
• Supports preventative care to minimize future split ends
• Works best combined with Extreme Length Conditioner and Sealer

Will it help my hair grow longer?

The product supports the conditions needed for length retention by reducing breakage and protecting delicate strands so hair can reach longer lengths over time. Growth rate is individual, but minimizing breakage is a key factor in achieving and maintaining longer hair.

• Creates a stronger foundation for length retention
• Helps reduce breakage that can prevent visible length gains
• Most effective as part of the full Extreme Length system

Is this suitable for my hair type and routine?

Extreme Length Shampoo is formulated for all hair textures, particularly hair that is fragile, chemically processed, or prone to snapping. It integrates into typical wash-and-style routines: shampoo, rinse, follow with conditioner, and add the leave-in sealer for targeted protection.

• Safe for color-treated and chemically styled hair
• Gentle enough for frequent use without weighing hair down
• Complementary with Redken professional treatments and styling products

Who is this for: Redken Extreme Length Shampoo is aimed at anyone struggling to grow hair past a fragile point—people with damaged, thinning, or breakage-prone hair who want a strengthening daily cleanser. Ideal if you regularly color, heat-style, or find strands snap before they reach your desired length. For best outcomes, use it with the Extreme Length Conditioner and Leave-In Sealer, and follow a consistent gentle-care routine to protect and preserve newly strengthened lengths.
