Olaplex wins on repair. Redken wins on condition.
Olaplex's bond-building approach genuinely rebuilds disulfide bonds, the more lasting structural repair. Redken Acidic Bonding is a pH-balanced conditioner that reduces breakage in the shower. Used together (Olaplex shampoo + Redken conditioner), they're complementary. For single-product choice: Olaplex for serious damage, Redken for damaged-but-less-severe.
