Introducing OLAPLEX's No 4P Blonde Enhancer Toning Shampoo, an update on the No 4 Bond Maintenance Shampoo with hardworking purple toner that will leave blondes three times brighter than regular purple shampoos.

Infused with patented OLAPLEX's Bond Building Technology, this customisable toning shampoo strengthens, softens, and neutralises unwanted yellow tones for brighter, more manageable hair. By combining a high concentration of pigment, with the brand's patented technology and conditioning benefits, this just became your new go-to purple shampoo. Use after the brand’s No 3 Hair Perfector weekly treatment and follow with the No 5 Bond Maintenance Conditioner.

HOW TO USE:

Apply to wet hair. Lather fully & let process 1-3 minutes. Rinse. For more intense toning, leave on up to 5 minutes.

TIP: Remove any buildup with No.4 Bond Maintenance™ Shampoo prior to using No.4P.
