I know lots will tell me it shouldn't be attempted, but I've gone from mid brunette to a lovely blonde using 40vol bleach x 2, Olaplex 1 + 2, and lots of purple shampoo and toner!
So it's a success and I'm delighted, but after the first bleach I waited 48hours before re-bleaching, how does this work when doing root touch up?? Will I have to have brown roots... then orange for a few days, then finally blonde??
I'm an amateur here....
