Blondes, are you ready to be unbreakable? With the launch of the new OLAPLEX Nº.4P, blondes, lightened hair and grey haired beauties are seeing brighter tones like never before. We cracked the code using our patented bond-building chemistry to create a purple shampoo that’s gentle on the hair, hydrating, and reparative.
Nº.4P repairs cleanses and tones with patented OLAPLEX technology for all blondes, lightened, and grey hair. While hydrating, Nº.4P neutralizes brassiness and brightens blonde. The highly concentrated pigment allows customizable toning levels ideal for medium to light blonde tones (levels 7 and up) in which yellow or brassy tones need to be controlled. Compared to top purple shampoos, users found their hair 3x brighter using OLAPLEX Nº.4P. The longer you treat, the brighter the toning results.
Inspired by salons, proven by science. No.4P Blonde Enhancer Toning Shampoo combines a high amount of pigment concentration with our patented bond-building technology & mild surfactants to provide a highly concentrated purple shampoo to deliver 3X brighter results (compared to top brands), yet gentle enough for frequent use (we recommend 2-3x weekly).
