OK I have a ? I was before I dyed my hair a dark blonde and went and bought a light blonde to dye my hair with... well when I dyed it the ends are light but the roots and top of my hair is real brassy in color... what would be the best way to correct it... should I put the other box of light blonde on it and try to see if it will fix it that way? I don't want to go to the salon to fix it simply because I can do anything they can here at home...
