Add shampoo. If your ends are very dry and you're dyeing your entire head, don't put dye on your ends. Instead, three minutes before you're supposed to rinse, add two squirts of shampoo into the dye left in the bottle. Shake it up and apply the mixture to your ends. "It dilutes the dye but still gives you a pinch of color and shine," says Louis Licari of the Louis Licari Salon in New York City. Let your hair down : You know how the models in the commercial always have their dye_coated hair artfully twisted up into a bun? Don't do that. "The color won't be even when you rinse it out," says Ionato. "Leave it down until the timer rings."
Highlight with a toothbrush. Several testers shared a smart trick for subtle results : Use a dye kit two shades lighter than your color and paint on highlights with a clean toothbrush or mascara wand. Place them sparingly where the sun would hit around the hairline and stemming from your part, Hill suggests. Start from the top : Since roots need the most color (and processing time), apply dye there first, then comb through the rest of hair to distribute it. Work in four to six sections, like pros do in the salon, to ensure full coverage.
