OLAPLEX No.5 Bond Maintenance Strengthening, Moisturizing Hair Repair Conditioner
by OLAPLEX · hair_care
Editor's Take
Patented bond-repair chemistry wrapped in a silicone-heavy, petrochemical-dense conditioning base; it works, but the clean score reflects the trade.
Four-pillar formula scores
- Efficacy: 8.8 / 10
- Modern Tech: 9.2 / 10
- Clean Beauty: 1.0 / 10
- Sustainability: 6.4 / 10
The Verdict
This is Olaplex's signature disulfide-bridging technology doing what it does best: rebuilding broken bonds inside the hair shaft while a dense network of quats, silicones, and biomimetic lipids smooth the surface. The formula is structurally advanced, pairing the patented Bis-Aminopropyl Diglycol Dimaleate with CMC-mimetic lipids and bio-fermented oils for both internal repair and immediate slip. The clean score is low because the conditioning base leans on ethoxylated surfactants, synthetic polymers, and persistent silicones. Worth it if bond repair is the priority and you're comfortable with the chemistry required to deliver it at this level.
