Also due to money this is definitely an at home thing. I'm pretty broke but my roots are showing so I either gotta go red again or change it up

If you're keen on doing at home it will take a few steps. But first you're going to have to get bleach/developer (if you go to a Sally's they'll help you find the right one). You will also need a very light blonde dye, something with cool/ash tones (not golden) if you want the icy toned blonde. Apply the bleach, wait, rinse out. You will probably end up with an unattractive yellowy-blonde colour. That's when you apply the blonde dye, which will hopefully give you a much nicer platinum.
I used to dye my roots this way, the first time I had it done I went to a salon, but this is basically what they did... it took like 5 hours, but I was dark brown to start. If you screw it up then you can always go in and have them fix it :P But just be aware that this will all be very very damaging to your hair.0
