Transcript

Okay, can we stop pretending purple shampoo is only for blondes? Because brunette hair gets brassy too. If your brown hair suddenly looks orange, dull, or weirdly warm after summer styling or color, this is exactly why. Dark hair still has underlying warm pigment, but over time those cooler tones fade first. Do you need blue or purple shampoo? Before, after. Before, after. Dark blonde/brunette for brassy orange undertones. Blonde/platinum/grey for brassy yellow undertones. Blue shampoo & conditioner, cleanse, tone & condition. Purple shampoo & conditioner, cleanse, tone & condition. So purple shampoos work because color theory is real. Blue cancels orange, purple cancels yellow. So you're neutralizing the brassiness without recoloring your hair. And for anyone like me, that colors their hair a lighter brown, this is super helpful to keep your color fresh and less brassy. Pro tip: Brunettes actually need to leave it on longer than blondes because the pigment has more depth to work through. Think 5 to 10 minutes, not a quick rinse. And if your color pulls super orange, try blue shampoo instead of purple that actually works better.
