Kate Walsh has a red hair secret: She uses three different shampoos to keep up the intensity of her auburn hue! “When you have hair that is colored and worked on every single day, you’ve got to spoil your hair a little bit,” the actress told InStyle.com. “And I don’t feel so bad because I read an interview with Sofia Vergara, where she said she uses eight!” Kidding aside, Walsh said her go-to is Bumble & Bumble’s True Red Color Support line ($23 each; bumbleandbumble.com). “Some shampoos for color-treated hair turn red hair a little pink, but Bumble & Bumble’s is a coppery red, which works great for me,” she said. “And I try not to wash it every day since red hair fades super fast.” See the redhead in a new episode of Private Practice tonight at 10/9c on ABC.
