Redken Extreme Length Biotin Shampoo for Longer, Stronger Hair - Shampoo

Redken Extreme Length Biotin Shampoo for Longer, Stronger Hair arrives as a professional-strength formula designed to nourish and fortify fragile lengths.

This 300 ml shampoo is specially formulated for women with damaged hair and works across all hair colours to deliver a strengthening effect that visibly improves resilience.

The professional shampoo contains key actives such as biotin and 2-oleamido-1,3-octadecanediol, supported by gentle cleansers like sodium laureth sulfate and cocamidopropyl betaine to remove buildup while protecting the fibre.

To use, apply to wet hair, massage into a rich lather and rinse thoroughly; for best results, follow with the Extreme Length conditioner and leave-in treatment as a complete system. Take care to rinse immediately in case of eye contact.

The product comes in a convenient bottle dispenser and is supplied as a single 300 ml unit, making it an easy addition to a home or salon routine focused on repair and length retention.

Ideal use cases include weekly treatments for chemically treated or heat-styled hair, a strengthening step in a growth-focused regimen, or a professional salon service where improving tensile strength and reducing breakage are priorities.
