My results! Now what?

Also when I apply shimmer lights my hair color is perfect, minus the purple but it doesn't seem to really change my hair color much after I rinse and also I'm going for a platinum/pale blonde look  *whip*

The general rule is at least a month between bleaches, or at least a week if you're just using a bleach bath.

I think you probably won't need a full bleach to get platinum blonde now, one or possibly two bleach baths should do it. You'll need to wait a month since you bleached, and give your hair some TLC in that month too - some coconut oil soaks, some deep conditioning treatments, etc. Then you can bleach bathe your hair; a bleach bath will only lift you one or maybe two shades but you're almost there now, so if one isn't quite right you can wait a week and do another.

Then you can use your purple shampoo as a toner - leave it on for 10 minutes, say - and you should go nice a platinum.

(I don't know anything about the Wella stuff, sorry.)
