Our take on the Olaplex No. 7 Bonding Oil

Olaplex No. 7 Bonding Oil is a 1-ounce finishing oil that adds shine, smooths frizz and offers heat protection up to 450°F. It is built around Olaplex's bond-building chemistry and works on damp or dry hair. Its price has held flat at $42.45 at Target since October 28, 2026, so there is no cheaper day to wait for.

Questions and answers

Is Olaplex No. 7 worth $42.45?
If you fight frizz and want shine plus heat protection in one step, yes; a bottle lasts months at a few drops per use. If you mainly want repair, put the money toward a treatment like No. 3 instead.
How is it different from Olaplex No. 6?
No. 6 is a styling cream for smoothing and hold; No. 7 is a lightweight finishing oil for shine and heat protection. Many people use No. 6 on damp hair and No. 7 as the final step.
How much should I use?
Start with two to three drops for medium hair, rubbed between the palms and worked through mid-lengths and ends. Add more only if needed; over-application is the main cause of greasy results.
Does it protect against heat styling?
Yes, Olaplex rates it for heat protection up to 450°F. Apply it before blow-drying or flat-ironing for the protection to count.
Can I use it on damp hair?
Yes. It works on damp hair before styling and on dry hair as a finishing shine. On damp hair, use it sparingly so it doesn't weigh hair down.
When is the best time to buy it?
The price at Target has been flat at $42.45 since October 28, 2026, so waiting hasn't paid off recently. Watch for salon or retailer sales and value sets instead.
