The Best Products To Keep Your New Hair Color Brass-Free

Photographed by Amelia Alpaugh.
If you dye your hair blonde, or even certain shades of brunette, brassy hues are like cockroaches after the apocalypse. They just keep on comin', reappearing no matter how cool-toned your original shade was. Blame the sun, your shampoo, or post-summer fun. Regardless of the cause, once that brass shows up, you gotta deal with it, stat. (Unless you like it, in which case, you do you — and maybe send this article to a friend who needs it.)
When your color turns brassy, it can be tempting to just call the salon and have it redone. But, that habit gets expensive real fast — plus, most colorists recommend waiting six to eight weeks between dye jobs to avoid damage. What's an unintentionally brass-ified girl to do? Ahead, the products you need to stay cool — in more ways than one.

This foaming gloss has a permanent place in our showers, for good reason. It once maintained the frosty baby-blond that Jessica Simpson sported at her wedding, so it can definitely cut through our brassy tones — and even prevent them. Use it after you shampoo, and let it sit for about five minutes. It'll make your locks extra shiny, too. "You'll notice a difference after one or two washes," celebrity hair colorist Rita Hazan tells us.

Worth noting: This product works well on blonde, brown, and gray hair.
