Your highlights called, and they want this shampoo

Purple shampoo is nothing new, and anyone who takes their blonde seriously likely hits the bottle once every week or so to keep color bright and ward off brassiness. My colorist got me started at least 10 years ago, and back then there were only a handful of purple shampoos laypeople like ourselves (i.e. non-professionals) could get their hands on, and Clairol Professional’s Shimmer Lights was one of them. The fact that it cost less than $10 at was available at the drugstore or supermarket gave me no excuse not to use it.

Fast forward to today, and virtually every upscale haircare brand includes a purple shampoo—however the latest incarnation from Olaplex stands out from the rest. Sure, No.4P Blonde Enhancer Toning Shampoo helps keep your blonde its brightest—but it also features the same signature Olaplex technology your colorist likely adds to your formula to help reinforce the bonds along the hair shaft that can become damaged with bleaching and over-processing. Even more, the sulfate-free formula actually lathers, and you can leave it on for up to five minutes before rinsing for even more of a brightening boost.

Unfortunately it won’t prevent your roots from growing in, but it can help keep your blonde looking as fresh as the day you got it done.
