Our Take

A newer addition to the range and arguably the most interesting for curl purists: an out-of-shower leave-in conditioner confirmed silicone-free by Olaplex, making it CGM-approved. Provides heat protection, helps mend split ends, and reduces breakage. The brand recommends using it in addition to (not instead of) your rinse-out conditioner. Fine curlies should use sparingly; it layers well with No.9 for extra protection.
