Hair to Dye For

For Easy Application

The latest technology, foam color, is "a mousselike product that stays put where you apply it," Canale says. "Foam is great for someone who's coloring her hair for the first time and wants to avoid dripping or making a mess."

Try Garnier Nutrisse Nourishing Color Foam ($9, drugstores)

Make It Last

Stick with either color-safe or color-preserving shampoos and conditioners, like Bumble and Bumble Color Minded Sulfate-Free Shampoo ($29) and Conditioner ($32, Sephora stores), that are free of hue-stripping sulfates. To prevent fading, Robinson recommends that you wash hair with warm water rather than hot, which can strip and damage color-treated strands.
