OLAPLEX No.5L Moisturize & Mend Leave-In Conditioner
by OLAPLEX · hair_care
Editor's Take
Patented bond repair meets rich plant butter in a silicone-free leave-in, but the conditioning base leans on quaternary ammonium compounds and undisclosed fragrance.
Four-pillar formula scores
- Efficacy: 8.8 / 10
- Modern Tech: 9.2 / 10
- Clean Beauty: 4.5 / 10
- Sustainability: 8.5 / 10
The Verdict
This is a credible structural treatment disguised as a leave-in conditioner. The Bis-Aminopropyl Diglycol Dimaleate at the top of the INCI list does real disulfide bond work, and the Murumuru butter and Squalane deliver weightless slip without silicones. The trade: Behentrimonium Chloride and Cetrimonium Chloride handle the conditioning, which keeps the clean score low despite the plant-forward lipid base. The fragrance allergen load is high for a leave-on formula. Worth it if you want bond repair in a daily product and can tolerate quats.
