OLAPLEX No.4 Bond Maintenance Strengthening, Hydrating Hair Repair Shampoo
by OLAPLEX · hair_care
Editor's Take
Olaplex earns its repair reputation here, but the clean-beauty shopper gets a crowded synthetic back room behind that very polished wash.
Four-pillar formula scores
- Efficacy: 9.2 / 10
- Modern Tech: 9.5 / 10
- Clean Beauty: 2.3 / 10
- Sustainability: 7.3 / 10
The Verdict
Performance is the easy sell: this is a top-tier performer in the shampoo category with exceptional efficacy alignment, led by Bis-Aminopropyl Diglycol Dimaleate and a mild Sodium Lauroyl Methyl Isethionate cleansing base. Cutting Edge is fair for the tech side, with Keravis™, Panthenol, and deposition polymers helping damaged lengths feel smoother after washing. Clean is the obvious trade-off: Fragrance, PEGs, Amodimethicone, acrylates, and quats make it a poor fit for strict clean-beauty baskets, even though the sustainability read is Good rather than grim. Worth it as a repair-minded daily shampoo for chemically treated hair, with the clean-label compromise sitting right on the counter.
