Don't trust the model on the box. Sure, the woman smiling on the front of the box looks beautiful, but the color of her hair is a fantasy. "The color always ends up lighter than the model's hair on the packaging," says colorist Dana Ionato of the Sally Hershberger Downtown salon in New York City. "The developer in at_home permanent dyes is very strong stronger that the ones we use in the salon so it lifts the color and makes it lighter than what you see on the box." A better estimate on how the color will end up is the chart on the top of the box, which shows you the final color you get from a range of different hair_color shades.
Add water. Before you rinse out the color, sprinkle a little water on your head and mush your hair around with your hands for a few seconds. "It emulsifies the dye and moves it all around so you don't end up with any lines or streaks," says Ionato. Tweak the results : After your hair is dry, if you're unhappy with the color, you can mute it by applying a deep conditioner to damp hair. Then cover your head with plastic wrap and a hot, damp towel. Leave on for 20 minutes (at ten minutes, blast your head with a blow_dryer), then shampoo and condition your hair. If you're still not happy with your shade, well, it looks like you're heading to the salon.
