OLAPLEX No.5L Moisturize & Mend Leave-In Conditioner

Editor's Take

Olaplex earns its treatment billing here: patented bond repair and Murumuru butter go well beyond routine detangling, though the fragranced quat base complicates the clean-beauty pitch.

Four-pillar formula scores

• Performance: 8.8 / 10
• Innovative Ingredients: 9.2 / 10
• Clean Standards: 6.0 / 10
• Formula Sustainability: 6.6 / 10

The Verdict

Bis-Aminopropyl Diglycol Dimaleate addresses damaged disulfide bonds, while Murumuru butter, Squalane, and AminoSensyl™ HC give dry lengths softness and cuticle control. The compromise is a conventional quat base with fragrance allergens and phenoxyethanol, so sensitive users have reason to pause. Among leave-ins, this is a credible treatment rather than a glorified detangler, with performance strong enough to justify the less pristine ingredient profile.
