Nailing a celebrity's hair color has never been easier! According to InStyle, Hendricks rarely strays from Clairol's Nice N Easy in Sandy Copper Blonde. "I was that same color red for about 20 years, and because I've been using it for so long, I know it will be consistent, and I know what it's going to look like," she explains. The star's top advice for dying your hair at home: "My main tip is not to leave it on for too long—that's the only mistake I've ever made."

In terms of aftercare, Hendricks likes to keep her haircare routine minimal. "I will use a color-safe shampoo and conditioner because it's milder, and I'm obsessed with the conditioner that comes in the dye box [like Clairol Nice 'N Easy CC+ Colorseal Conditioner]; I love that stuff," she revealed to Glamour. "Also, going a couple of days without washing it helps keep the color fresh longer. And I always wear a hat when I'm in the sun because it bleaches my hair so quickly," she added.
