Overview
Olaplex No. 9 Bond Protector is a 90ml lightweight hair serum built to shield strands from heat up to 450F/232C and reduce tangles, static and frizz on damp or dry hair of any texture.
This sits in Olaplex's line as a heat-protecting finishing serum rather than the brand's bond-repair treatments, so it is meant to be layered before styling rather than used as a standalone repair step. It is color-safe and vegan, and applies to damp or dry strands.
- 90ml serum with PVP and cetrimonium chloride
- Heat protection up to 450F/232C
- Brand-stated 48-hour pollution protection
- Color-safe, vegan formula
Who it's for
Fits anyone who heat-styles regularly and wants added shine, softness and static control before using tools. Less necessary for hair that air-dries without heat.
Pros and cons
- Heat protection rated to 450F/232C
- Reduces tangles, static and frizz
- Color-safe and vegan formula
- Works on damp or dry hair of any texture
- Small 90ml bottle for frequent heat-styling use
- A finishing serum, not a standalone bond-repair treatment
Performance notes
PVP, a flexible polymer, helps hold style shape and cuts frizz, while cetrimonium chloride conditions strands and reduces static. Together the brand states this combination protects hair up to 450F/232C and adds a claimed 48-hour shield against pollution exposure, applied to damp or dry hair before styling.
