A next-generation leave-in treatment that works in just 4 minutes, using patented K18PEPTIDE technology to reconnect broken polypeptide chains and disulfide bonds at a molecular level. Lightweight, silicone-free, and no-rinse — it reverses damage from bleach, colour, chemical services and heat for soft, strong, bouncy hair. Like Olaplex No.3, you're getting serious science-backed bond repair that goes beyond surface conditioning — this targets the actual structural chains inside the hair fibre, not just the outside. It's a treatment ritual that sits apart from your normal shampoo-and-condition routine, making it a direct spiritual sibling to the No.3 in how you use it. Where it diverges is its leave-in format and biomimetic peptide approach, which means you apply it post-wash and simply don't rinse — no sitting with it wrapped in a towel for 30 minutes. If you love the purposeful, weekly repair ritual of No.3 but want something that works faster and feels lighter in the hair, K18 is the natural next step.

An intensive rinse-off pre-shampoo treatment powered by a 12% Citric Acid Complex that targets and recreates inner broken hair bonds from the inside out. Used before shampooing, it delivers up to 98% less breakage, 90% more shine, and 82% stronger hair. This is the closest match to the Olaplex No.3 experience in terms of usage ritual: you apply it before you shampoo, leave it to penetrate, then rinse — exactly the kind of dedicated, step-one bond repair moment that No.3 built its reputation on. The bond-rebuilding chemistry via Citric Acid Complex mirrors the core mission of strengthening damaged hair from within. It's a smart pick if you want to access that same premium-feeling treatment format at a more accessible price point, without compromising on the underlying science. L'Oréal's concentration of active ingredients here is genuinely high, making this a serious contender for bleached, coloured or heat-damaged hair.

A professional-grade, 5-minute rinse-off pre-shampoo treatment with Redken's highest concentration of 14% Citric Acid and Bonding Care Complex. Delivers up to 2x stronger hair and 14x smoother results after just one use — salon credibility in a bottle you can use at home. The wildcard here is the professional pedigree: this is a salon-brand formula that hairdressers use backstage brought into your home routine. It shares the same weekly pre-shampoo format as No.3, but the 14% Citric Acid concentration takes the bond-repair potency up a notch — a genuinely noticeable step up for heavily processed or bleached hair. If you've been loyal to the Olaplex system and want to try something that operates in the same treatment world but with a different formulation philosophy — and one that reviewers frequently describe as outperforming No.3 on severely damaged hair — this Redken pre-treatment is the discovery worth making.
