Olaplex No.4C – The Clarifying Shampoo That Actually Repairs While It Cleans

Most clarifying shampoos make a deal with the devil. Yes, they strip buildup — but they also strip moisture, colour, and whatever integrity your hair had left. You're left with clean hair that feels like straw. Olaplex No.4C Bond Maintenance Clarifying Shampoo tears up that deal entirely.

This is clarifying reimagined. The same patented bond-building technology that made Olaplex a global phenomenon is built into every drop of No.4C — meaning while it deep-cleans product buildup, hard water minerals, and environmental pollutants from your scalp and strands, it simultaneously seeks out and repairs broken disulfide bonds at the molecular level. Cleaning and restoring happening in the same lather. At the same time. No compromise.

The shine restoration is immediate and genuinely impressive. Once buildup is cleared and bonds are reconnected, light reflects off the hair surface the way it's supposed to — evenly, brilliantly, with a glossy finish that no amount of serum can fake on top of dirty, compromised hair.

Use it once a week, once a fortnight, or whenever your hair feels heavy and dull — No.4C slots into any routine without disrupting it. Follow with No.5 conditioner or No.8 bond intense moisture mask and the results compound with every use.

Sulphate-free. Vegan. Safe for colour-treated hair — because of course it is. This is Olaplex. Colour protection isn't an afterthought, it's built into the DNA of everything they make.

Reset your hair. Restore your shine. No.4C does both without asking your hair to pay the price.
