OLAPLEX’s No 4P Blonde Enhancer Toning Shampoo. An update on the classic No 4 Bond Maintenance Shampoo, this new addition stars the same patented active ingredient that seeks out broken bonds in the hair (which are caused by chemical, thermal and mechanical damage) and repairs them, restoring compromised hair to former glory, but now with a purple toner to help keep warm toned hues from your precious hair.
For all blonde, lightened and grey hair.
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.
