Olaplex No.9 Bond Protector Nourishing Hair Serum 3 oz / 90 ml - Ultimate Heat & Pollution Shield
No.9 is the leave-in in the Olaplex range, and the simplest way to think about it is as the step that guards the work the other numbers have done. It is a serum rather than a cream, silicone-free, and it goes on damp hair before you style.
Two protections run at once. The antioxidant side takes on pollution, and Olaplex put a 48 hour figure on that. The heat side covers you to 232C, so straighteners and tongs are not going in unprotected. Bond Building Technology sits underneath both.
- Heat cover to 232C
- Pollution defence for up to 48 hours
- Cuts static, so hair stops clinging in cold weather
- Satin finish rather than a wet-look shine
- 90 ml
Silicone-free matters more than it sounds. A silicone serum smooths by coating, and the coating builds until you clarify. This one leaves hair easier to handle without that trade, which makes it usable several times a week rather than occasionally.
