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 the blonde. The highly concentrated pigment allows customizable toning levels ideal for medium to light blonde tones in which yellow or brassy tones need to be controlled. The longer you treat, the brighter the toning results.
