"in general you should wait a week, but you should use your discretion. if your hair is pretty much destroyed you should completely avoid chemical processes. it just depends on how much you think your hair can handle. always do a strand test to make sure too, just in case."

"this is why you always need to do a strand test before you dye all of your hair. every time you need to bleach it back you do a lot of damage, so you need to be careful with the colors you choose. i would say the best thing to do right now is to use a veggie violet toner. this will condition your damaged hair, and the violet will cancel out the yellow from having bleached hair, so you will end up with a soft natural white/platinum blond. i hope this helps!"
Sounds like you should be OK dying it, just do a strand test to make sure it's going to look how you want.
Thanks. What should I wait a week from, since I last dyed it?
Veggie violet toner? Never heard of it, I could imagine it to be quite hard to get hold of.
Kudoss!
