OLAPLEX have given the people what they want, a staple for every blonde - a customisable toning shampoo that strengthens, softens and neutralizes unwanted yellow tones for brighter, more manageable hair. This highly pigmented purple shampoo is scientifically proven to provide 3x brighter results compared to the top purple shampoos on the market. The sulfate-free formula creates a rich lather to neutralize brassiness for all blonde, lightened, and grey hair. Depending on the level of toning required, the shampoo can be left on for as little as one minute or for a maximum of 5 minutes - the longer you treat, the brighter the results.
The most frequent issue with purple toning shampoos is that they dry the hair. With OLAPLEX No.4P Blonde Enhancer Toning Shampoo this is a problem of the past, this highly concentrated purple shampoo hydrates the hair from roots to end whilst cleaning, toning and repairing.
