Olaplex Nº4 Bond Maintenance Shampoo: Reduce Breakage, Strengthen & Detangle – For All Hair Types, 100 mL

Olaplex Nº4 Bond Maintenance Shampoo: Color-Safe Cleansing for Stronger, More Manageable Hair

This highly concentrated, color-safe shampoo targets bond health while delivering a thorough cleanse that leaves hair feeling smoother, shinier, and easier to manage with each wash. The formula relies on coconut oil–derived surfactants to create a rich, abundant lather that hydrates the scalp and hair without stripping moisture.

Designed for all textures—coily, curly, straight, and wavy—it works as part of a broader care routine to help reduce breakage and support softness and shine over time. When used regularly, you may notice improved detangling and longer-lasting smoothness, even on color-treated hair. The product is gentle enough for daily use and pairs well with other Olaplex treatments to form a reinforcing system.

Key benefits

• Reduces breakage and strengthens hair
• Gently cleanses without stripping moisture
• Hydrates, smooths, nourishes, and detangles

Clinically tested benefits are often described when used as part of a system with Nº3 and Nº5, including smoother detangling and improved conditioning. While individual results vary, many users report a noticeable difference in texture and manageability over time.

How to use for best results

• Apply to wet hair, massage from scalp to ends, then rinse thoroughly.
• Follow with No.5 for daily use or your preferred conditioner to seal in moisture.
• Use as part of a regular wash routine to maintain hydrated, supple hair and easier detangling.

Tip: If you wear color, this shampoo is formulated to be color-safe, helping you maintain vibrant tones while supporting hair health. Use it consistently to support a balanced cleanse that respects scalp and strand integrity.
