Extreme Length Conditioner with Biotin — Reddit Reviews
by Redken
Updated November 6, 2026
Lightweight conditioner for fuller-feeling fine hair and less breakage; detangling is rough.
What the community says
A lightweight rinse-out conditioner with biotin, castor seed oil, glycerin, and mineral oil that leaves hair soft without a greasy finish. Fine-haired users chasing less breakage may like it, but serious detangling problems and occasional dry, flaky scalps are deal-breakers.
