Olaplex No. 9 Hair Serum

Step 1: As the first step in your styling routine, apply a small amount to damp hair, working upward from ends to roots.

Step 2: Use more as needed for longer, thicker hair.

Step 3: Style as usual. Use on wash days and any days in between for added protection.

Pro tip: Suitable for all hair types and textures, it layers under any styler without weighing hair down.
