Introducing OLAPLEX's No 4P Blonde Enhancer Toning Shampoo!
 
The new Olaplex turns 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. 
 
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.
