Use two mirrors : Coloring the back of your head can be tricky. As you apply dye in front of your bathroom mirror, hold up a handheld one to ensure you don't miss spots, Hill recommends. Have cleansing cloths on hand : Use wipes like Neutrogena Makeup Remover Cleansing Towelettes to soak up any dye splatters as they happen. If you wait until you're done, they may have already set. ("I still have stains I can't get off!" one tester sighed.)
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!
