Why You’ll love it

Fresh, light scent and creamy lather make wash day more enjoyable.

Description

Redken Extreme Length Shampoo with Biotin is a strengthening shampoo that supports longer-looking hair with less breakage.

This creamy formula gently cleanses from root to tip, helping to remove daily build-up while protecting fragile lengths. Biotin and strengthening polymers work together to fortify weak strands, so hair feels stronger and less prone to snapping.

The lather feels soft and cushiony, with a light, clean scent that doesn’t overpower. Hair is left feeling smoother, easier to detangle, and ready for conditioner without that stripped, squeaky feel.

Ideal for those growing out their hair, dealing with split ends, or noticing breakage when brushing. Use it as your everyday shampoo to support longer, more resilient hair that feels touchably soft and looks more polished from roots to ends.

Directions

How To Use Redken Extreme Length Shampoo with Biotin

Wet hair thoroughly with warm water.
Apply a small amount of shampoo to scalp and roots.
Massage gently to create a rich lather, working through lengths.
Rinse thoroughly until water runs clear.
Repeat if needed, then follow with Extreme Length conditioner or treatment.
