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.
Use a shower cap : Once all color is on (but before you wander around) cover hair with a disposable shower cap to keep dye from dripping and staining. Then you can feel free to prep dinner or Netflix_binge. Get extra gloves : You slipped on the box's plastic gloves to protect your hands while putting on the dye, but you need to wear them while washing it off too. Have a fresh pair ready in case you can't reuse the originals. A tester who forgot ended up with seriously stained fingers!
