I have a racoon tail and the ends of my layers bleached, i'm wanting to do a dark brown/black on the unbleached part of my hair and a purple on the bleached parts but I dont know how to go about it. I was thinking to do the purple first then do the black the next night so the black doesnt bleed on the bleached parts but would it still bleed onto the purple? Any tips or tricks on how to do this?🥲
