How do you wash you hair whilst preventing colour from black dye running onto bleached parts of hair??

So the heading pretty much says it all. Im bleaching parts of my hair, dying them pink, then dying the left over bits black. I just wanna know how i wash my hair, without black dye running onto the the bleached parts and going a gross, green dirty colour.How do you wash you hair whilst preventing colour from black dye running onto bleached parts of hair??
Hmm, that could be tough and its happened to me which resulted in me having the blonde parts be gray -_-





just try to keep the bleached ones as separated as possible, and when you rinse it out maybe have someone help you make sure the dye doesnt get on the blonde. But if it does turn a little grayish I'm sure once you put pink over it it wont be noticable.


If it does turn a really bad colour just bleach it a little bit to get rid of it.





good luck!
