No. 4P Blonde Enhancing Toner Shampoo

About

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 (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, but we recommend starting with one minute and going from there.

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 and 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).

Clinically tested, stylist approved. Alternate washes with N°4 Bond Maintenance™ Shampoo as often as needed. Compared to top purple shampoos, users found their hair 3x brighter using OLAPLEX Nº.4P. We cannot wait to see all the unbreakable blondes! 

OLAPLEX products are thoroughly tested in-house and by independent third-party laboratories for safety and efficacy. This product testing includes the industry standard Human Repeat Insult Patch Test (HRIPT), which tests for skin irritation or sensitivity. All of OLAPLEX products passed the HRIPT, meaning the products show no signs of causing irritation, inflammation, or sensitivity.
