Olaplex No. 7 Bonding Frizz Reduction & Heat Protectant Hair Oil
by Olaplex · hair_care
Editor's Take
A bottle of silicone masquerading as an oil, built for instant shine and heat defense, not strand nutrition.
Four-pillar formula scores
- Efficacy: 7.4 / 10
- Modern Tech: 5.8 / 10
- Clean Beauty: 2.8 / 10
- Sustainability: 0.0 / 10
The Verdict
Marketed as an oil, formulated as a silicone serum with a splash of plant extracts. Dimethicone and Phenyl Trimethicone lead the formula, delivering professional-grade shine and thermal protection up to 450°F , the efficacy is real, the frizz control is immediate, and the heat shield works. But the base is pure legacy salon chemistry: persistent silicones, petrochemical hydrocarbons, and a chemical UV filter that tanks the clean score to 2.8. Worth it if you need high-gloss armor for heat styling and don't care what's coating the cuticle.
