Olaplex Nº.4 Bond Maintenance™ Shampoo is a concentrated bond-repairing cleanser that strengthens hair, reduces breakage, and restores hydration in a single wash.
Designed for medium-to-coarse textures across straight, wavy, curly, and coily hair, this color-safe, vegan shampoo cleans without stripping and targets everyday damage at the molecular level. It produces a rich lather that gently lifts dirt and product buildup while replenishing moisture and smoothing the hair surface for improved manageability and shine.
Many users notice improved softness, smoother texture, and easier detangling after the first wash when used as directed. Strengthening effects accumulate with repeated use as the patented bond-reinforcing technology integrates into the hair structure.
Yes — the formulation is color-safe and suitable for chemically treated hair. It gently cleanses while preserving color vibrancy and helps reinforce fragile areas created by chemical processes.
The shampoo was engineered for medium to coarse hair and performs well across all porosities. It supports straight, wavy, curly, and coily patterns by repairing bonds and restoring manageable moisture balance without weighing hair down.
The shampoo foams richly and rinses clean while leaving hair feeling soft rather than stripped. Expect smoother strands, reduced tangles, and a polished appearance after drying, especially when paired with complementary Olaplex products.
Who is this for: Olaplex Nº.4 Bond Maintenance Shampoo is ideal for anyone with medium to coarse hair seeking to repair everyday wear, lower breakage, and improve shine and manageability. It’s a strong fit for color-treated or chemically processed hair, those combating frizz and split ends, and anyone who wants a gentle yet effective daily-strength shampoo that supports longer, healthier-looking hair.
