Redken Extreme Length Shampoo 33.8 fl oz — Biotin Strengthening Formula to Reduce Breakage

Redken Extreme Length Shampoo is a biotin-enriched strengthening shampoo that gently cleanses damaged, fragile hair while helping reduce breakage and support longer-looking lengths.

Designed by the salon pro brand Redken, this 33.8 fl oz formula combines a mild cleanse with a fortifying Length Care Complex and biotin to reinforce strands from root to tip. It’s formulated to work as part of a full system—shampoo, conditioner and leave-in sealer—to help hair appear stronger and reduce the visible signs of split ends when used consistently.

How does this shampoo help hair grow longer?

The shampoo focuses on strengthening weakened hair rather than accelerating biological growth. By reinforcing the fiber and reducing breakage, hair can retain more length over time. Use with the matching conditioner and sealer for a complete regimen that maximizes the strengthening benefits.

• Contains biotin to help fortify the hair fiber
• Length Care Complex supports strand resilience root to tip
• Large 33.8 fl oz size for frequent use and salon-style routines

Will it reduce split ends and make hair look healthier?

This formula helps minimize the appearance of split ends by strengthening and smoothing the surface of the hair. While it won’t restore already-cut split ends, it reduces new breakage and makes strands look more uniform and healthy when used regularly.

• Visibly reduces the look of split ends when used as a system
• Strengthening action helps prevent further strand fraying
• Gentle cleansing keeps hair manageable without over-drying

Is Redken Extreme Length Shampoo suitable for all hair types and textures?

The shampoo is formulated to be compatible with various hair textures, including fine, medium and coarse. It’s particularly useful for hair that’s fragile, chemically treated or prone to mechanical damage from styling, but it can be included in most care routines to add resilience.

• Works on color-treated and chemically processed hair
• Suitable for daily or regular use depending on hair needs
• Safe to combine with other Redken professional treatments

How should I use it to get the best results?

For optimal performance, massage into wet hair, rinse and follow with Redken Extreme Length Conditioner and the matching leave-in sealer. Consistent use over weeks supports stronger strands and reduced breakage compared to non-conditioning shampoos.

• Apply to wet hair, lather, rinse thoroughly
• Follow with Extreme Length Conditioner and Sealer for system benefits
• Use regularly; system results are cumulative over time

Who is this for: Redken Extreme Length Shampoo is ideal for anyone with fragile, weakened, or damage-prone hair who wants to protect existing length and reduce visible split ends. Professionals and everyday users who prefer salon-grade formulas will appreciate the large bottle size for frequent use. If your primary goal is to minimize breakage and support stronger-looking hair while maintaining a gentle cleanse, this formula is designed to fit into a routine that favors strength, manageability, and longer-lasting length.
