Hair failure :(

There's a lot of things going on here.

Bleaching your hair twice in two days could easily have been enough to have damaged your hair to the point that the cuticles have been ripped off. This means there's nowhere for the dye to cling on to and so just washes off easily.

Manic panic and ion are not the best dyes, by far. Some people love manic panic, but most of us finds it washes out fast. Use Special Effects or Directions and they're likely to last longer as the purples are more highly pigmented and tend to stain more (sometimes a bad thing if you want to change often!).

You need to wash your hair less. I know, it's super oily. It's almost certainly super oily because you over wash it and with shampoo that's harsher than it needs to be. Generally, unless you live in a huge city like London, New York, or any other over populated and highly polluted city once a week is more than enough to remove dirt, but your scalp needs time to get used to it. If it doesn't and it's still getting oily after a few months, then it's possible there's something else wrong and a doctors visit might be in need. But mostly, we need to get used to the idea that hair needs a little oil! A little oil for a day or so as you're stretching washes out is not a bad thing. You just adapt with hairstyles that help mask it.

Conditioner only washing is a good method of keeping colour, but also washes quite effectively. Many of us here co wash once a week.it would even be a better way of washing for you if you don't want to cut down from every other day. You just need a silicone free, light conditioner to 'shampoo' and then a slightly heavier one to finish off with.

Purple shampoo, while I get the logic of what the person in Sally's suggested, isn't really the best way. The shampoo is probably quite harsh and due to the condition of your hair it's likely it's washing out more dye than it can deposit. You'd be better off adding some of the manic panic or ion to your conditioner and leaving it on for 10 mins when you wash. I've been washing my hair about once a week for my entire life and I only really start to feel oil in my hair when it's been more than a week and I've forgotten to wash!

For future reference. When you've been using box dyes and you want to go lighter, use a colour remover before reaching for the bleach! You can use them up to three times. They're a little drying, but a good conditioner will sort that out. Only then, after another week to make sure the colour remover has fully done its job, should you bleach.

Also you can still use a colour remover now to get some of the staining from your lengths. I would wait a bit to let your hair recover somewHat from bleaching first.
