Redken Extreme Conditioner is a professional hair-strengthening conditioner for damaged, distressed and brittle hair, formulated around Redken's Strength Complex — a blend of amino acids, arginine and citric acid that works to reinforce and smooth the hair fiber after shampooing. It detangles, helps fortify weakened areas along the hair shaft, and leaves hair feeling more supple and looking shinier without adding heaviness.
As part of Redken's complete Extreme system — Extreme Shampoo, this conditioner, and the Extreme Anti-Snap leave-in treatment used together — Redken reports breakage reduced by up to 75% compared to a non-strengthening routine; used on its own, this conditioner contributes to that result, but the published figure reflects all three steps used together, not the conditioner in isolation.
The formula is built on conventional conditioning agents (cetearyl alcohol, behentrimonium chloride) plus silicone derivatives for slip and shine, along with hydrolyzed soy protein and arginine for strengthening — it is not a natural or organic formula, and is intended for damaged or over-processed hair rather than as a routine everyday conditioner for healthy hair.
- All hair types, textures and lengths experiencing damage, breakage or brittleness
- Salon-quality professional formula, safe for at-home application after shampooing
- Best used alongside Extreme Shampoo and Anti-Snap for the full strengthening system
