Badly Need coloring advice!!

Box dyes are not a good choice to begin with lol. Blonde box dyes were made for girls with already light blonde hair. You can try toning your roots now to take out the orange you can get white lady from sally's since i am assuming your going to do this your self. If that doesn't take out enough of the orange your going to have to bleach it out. You can get bleach from sally's as well even though i personally wont use there products as i feel they are more damaging then redken bleach, matrix, scruples, etc. The reason it turned so much more orange this time is because you said it... let your roots grow out to much. So the color activates off of the heat of your scalp and the less heat it gets from your scalp from being further away it activates at a different pace.
Hope this helps and let us know of any other questions.
