Olaplex No.4 Bond Maintenance Shampoo Liter 33.8 oz

Deeply nourish, strengthen, and smooth damaged hair with Olaplex No.5 Bond Maintenance Conditioner Liter (33.8 oz), a professional salon size conditioner designed to repair broken hair bonds while restoring softness, shine, hydration, and manageability. Powered by patented OLAPLEX Bond Building Technology™, this highly concentrated conditioner helps repair everyday hair damage caused by coloring, bleaching, heat styling, environmental stress, and daily wear without weighing the hair down. 

Unlike ordinary conditioners that only coat the surface of the hair, Olaplex No.5 works on a molecular level to help reconnect broken disulfide bonds inside the hair structure. The result is hair that feels healthier, softer, smoother, and visibly less frizzy with continued use.

Its rich creamy texture hydrates medium to coarse hair while still rinsing clean without excessive heaviness or buildup. The sulfate free, vegan, and color safe formula is suitable for chemically treated, bleached, highlighted, curly, coily, straight, and wavy hair types.

Many beauty editors and users praise the conditioner for improving manageability, reducing breakage, and leaving hair noticeably shinier after regular use. Allure readers voted the No.4 and No.5 duo among their favorite hair repair products because the system helps hair become “smoother and shinier” over time.

Why You’ll Love It

Unlike heavy repair conditioners that can leave hair greasy or flat, Olaplex No.5 delivers intensive hydration while maintaining softness, movement, and bounce.

Beauty editors at Vogue described Olaplex as “hair insurance” because of its bond repairing technology that helps strengthen hair from within rather than temporarily masking damage.

Users with bleached, dry, frizzy, and color treated hair often mention that the conditioner leaves hair noticeably softer, smoother, and healthier looking after just a few uses. Sephora reviewers also highlighted improvements in shine, manageability, and overall hair texture.
