To keep your hair from getting orange, put something that's on the opposite side of the color wheel on top of it, and bam! Brass neutralized. Blondie Bella uses purple shampoo every other day, and says it definitely helps you get the most wear out of your color. If you have any gray hair, these are also great to keep it from taking on a yellowish cast. There are also enough options to satisfy most people's needs, from drugstore bargains like One 'n Only Shiny Silver Conditioning Shampoo ($5) to more natural products like Lush Daddy-O ($9) and Unite Eurotherapy Blonda Shampoo, which is only available in salons. A brighter future (at least on top of your head) is a shampoo away.
