Redken Extreme Length Conditioner with Biotin is a nourishing conditioner for breakage-prone hair, made with biotin, castor oil and a 4% Length Care Complex to help strengthen fragile strands and ends.

It follows Extreme Length Shampoo and conditions the older, more fragile lengths where breakage usually starts. Used in the complete Extreme Length system with the shampoo and Sealer, Redken reports 81% less breakage compared with a non-conditioning shampoo, and the system is suitable for colour-treated hair.

Biotin, castor oil and 4% Length Care Complex
Nourishes and conditions fragile ends
Suitable for colour-treated hair
Sizes: 10.1 oz (300 ml) and 33.8 oz (1000 ml)

People growing their hair whose mid-lengths and ends are dry, fragile or splitting. It suits most hair types including colour-treated hair and is made for everyday home use.

The ends of long hair are the oldest and most worn part of the strand, so that is where length is lost. Extreme Length Conditioner puts castor oil, biotin and its 4% Length Care Complex exactly there, and as part of the three-step system Redken measured 81% less breakage. If you are already using the Extreme Length Shampoo, this is the step that does most of the conditioning work.

After shampooing with Extreme Length Shampoo, apply to damp hair.
Distribute through the lengths and ends, then rinse thoroughly.
Follow with Extreme Length Sealer. In case of contact with eyes, rinse them immediately.

Pros:

Castor oil and conditioning agents soften dry ends
Biotin-based Length Care Complex aimed at keeping length
Suitable for colour-treated hair
Litre size available

Cons:

Can feel rich on very fine hair; keep it off the roots
Contains mineral oil
Reduces breakage rather than speeding up growth
