Olaplex no. 4 Blonde Enhancer Toning Shampoo is infused with patented Olaplex Bond Building Technology. This customizable toning shampoo strengthens, softens and neutralizes unwanted yellow tones for brighter, more manageable hair.

How to use:

1. Apply to wet hair.  Lather fully and let process 1-3 minutes. Rinse. For more intense toning, leave on hair up to 5 minutes.
2. Follow with No. 5 Bond Maintenance Conditioner for everyday moisture or No. 8 Bond Intensive Moisture Mask for extra hydration.

We recommend pre-washing with No.4 Bond Maintenance Shampoo to remove product buildup.
