Nº.4P Blonde Enhancer Toning Shampoo. 1 in 3 women have blonde hair, whether naturally or salon enhanced. Thanks to OLAPLEX, many of those blondes are healthy. When creating a new product, we thought, how do could we improve every step of the clients’ at-home care, which until now, hasn’t included colour. Say hello to our first foray into colour, Nº.4P!

Nº.4P repairs, cleanses, and tones with patented OLAPLEX technology for all blondes, lightened, and grey hair. While hydrating, Nº.4P neutralises brassiness and brightens the blonde. The highly concentrated pigment allows customisable 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!
