Digital Studio In the past touching up your roots was a messy proposition that involved bowls, brushes and invariably a few stains.

The Mixer by Colour Revolution comes in a syringelike applicator that eliminates the need for mixing-just aim it at your regrowth, squeeze out the formula, leave it in for 30 minutes, and then wash it out. Another shortcut: Revlon Color Silk Root Perfect, which features a built-in sponge applicator. 06 of 06 Eye Lights Time Inc.
