Olaplex N°.7 Bonding Hair Oil — 450°F Heat Protection

What is it and what's it for?

Unlike a regular shine oil, this one contains Olaplex's 'bonding' technology that helps rebuild the internal bonds of damaged hair, in addition to protecting from flat-iron and blow-dryer heat up to 450°F.

Real-world use cases

• In your daily routine: You apply it to wet hair before drying or flat-ironing — it protects from heat and adds shine, two steps in one.
• Professional use: A hairstylist uses it before any heat tool (flat iron, dryer, curling iron) to reduce cumulative damage in clients who style with heat often.

How to avoid buying the wrong one

• It's applied to wet hair BEFORE using heat — applying it after doesn't give the same heat protection.
• It also works on dry hair as a finishing shine touch, in a minimal amount (2-3 drops).
• It doesn't replace a deep repair treatment (like Olaplex No.3) if hair is already very damaged — this is prevention, not intensive repair.
