Platinum Purple Showdown: Cools Brass, Tested Highlights, (Blonde magic!) We’ve tested countlessPurple shampoos, but the Paul Mitchell Platinum Plus truly delivers. Designed for medium to dark blondes and highlights, it tackles brassiness with precision. The purple hue neutralizes warm tones instantly, transforming our hair from dull and brassy to cool and vibrant. Our strands felt instantly refreshed, without stripping moisture—a rare find in purple clean-up treatments. The first wash noticeable difference was ours—it balanced tones and amplified brightness without compromising texture. While it’s not a miracle worker for severe discoloration, it’s an excellent日常 maintenance tool. We appreciate how it leaves hair feeling soft and polished, not ashy. For those targeting warm undertones, this is a must-try. The platinum formula delivers its promise, making us question if we’ve found our holy grail of purple magic.
