When you dyed your hair from blonde to black you thought it would look totally hot, but it definitely did not. If your hairdresser is booked solid until next month, or you just can't stand the idea of going in public looking the way you do, don't worry, it's easier than you think to fix the problem yourself at home.
Follow all instructions on the removal kit to remove unwanted dye from your hair. The solution will not only strip the dye from your hair, but also most of your natural hair color. After washing out the solution, you should be left with a fairly unattractive brassy shade of hair. This is normal, no matter what your natural hair color is.
Wait one day before applying the hair dye. Hair-dye removal kits weaken the hair, and the natural oils in the scalp will protect the hair follicles from the additional harsh chemicals of the dye. Do not wash your hair prior to dyeing it.
Mix the hair dye according to the specifications and your desired color. Set aside for several minutes for the color to develop. While the color is developing, rub Vaseline on your forehead and neck along the hairline and put on a pair of gloves to prevent the dye from staining your skin.
Work the dye evenly through the hair starting at the ends and working toward the roots. The heat from your head causes the color of the dye to develop more quickly at the roots than in the rest of your hair. Let it set for the specified amount of time and rinse thoroughly until water runs clear.
Apply a deep-conditioning treatment to your hair weekly. Excessive dying can lead to weak and brittle hair that feels very dry to the touch. The deep-conditioning will prevent breakage and leave your strands silky smooth.
