Our verdict

A concentrated styling oil for anyone heat styling who wants shine, frizz control and protection from a few drops. It is a finishing and styling oil, not a bond repair treatment step.

Overview

Heat stylers and anyone fighting frizz get a weightless Olaplex bonding oil that adds shine and protects hair from hot tools. A few drops smooth flyaways, and a blend of coconut derived emollient, vitamin E and sunflower seed oil conditions the strands.

Heat protection plus long frizz control from a few drops makes a small bottle last through many styling sessions. Using too much can weigh down very fine hair.

Who it's for

People who blow dry or flat iron often, including those with color treated or bleached hair. Anyone wanting a deep repair mask or rinse out treatment should look at other steps in the line.

Pros and cons

Pros
  • Heat protection for hot tools
  • Long lasting frizz control
  • Few drops per use
  • Works on all hair types
Cons
  • Can weigh down very fine hair
  • Small bottle size
  • Not a rinse out treatment

Performance notes

Shine and smoothness come from the emollient blend coating the hair surface, which also slows humidity from reaching the strand. Heat protection depends on applying it evenly before styling, so spread the drops through mid lengths and ends.
