Revlon Root Erase by ColorSilk

Covering your roots either means spending an hour in the salon (and dropping a sizeable amount of cash to conceal a minor amount of gray) or making a mess of your bathroom with a DIY touch-up kit. But this drip-free sponge applicator and ammonia-free formula get rid of roots in 10 minutes. Plus, each shade seamlessly blends with at-home or salon haircolor brands—making the process foolproof.
