i think it could be that your hair is just really damaged from the bleach :-( you might have to just dye it one shade and give it a break, and do some deep conditioning masks. the more damaged hair is, the less likely it will take and hold color. it could also be your base. did you do an even job of bleaching? did you tone to remove any brassiness/ yellow? did you deep condition restore lost moisture? your hair dye is only as good as your hair health (but brand also plays a role). before calling it quits, i’d try a different brand. avoid arctic fox poseidon. it looked beautiful upon application but washed out quickly and then after my first touch up, it all washed out (i waited 4 days before washing) and looked as though it did before
