If you have platinum-blonde or near-white hair, you know the struggle: Brassy orange tones are your enemy. Even under the care of hair-color genius Aura Friedman, I feel like I'm perpetually trying to tone it, trying nearly every purple shampoo and conditioner on the market to neutralize unwanted warm tones. And there's no doubt that some shades are stronger than others. You can tell by the color of the formula itself: Some are bright purple, while others are closer to silvery lilac. But I've noticed that many of the options with more-intense pigments can actually be quite drying. That is, until I found this.
