What it is
A leave in oil serum carrying COSRX's 132 peptide complex, designed to bond down raised cuticle and seal split ends without weighing hair flat.
Why we chose it
COSRX brought its skincare discipline to hair and it shows. This is the finishing step that makes second day hair look intentional rather than tired.
How to use
Two or three drops through damp ends before drying, and one drop on dry hair to finish. Avoid the roots.
