A few month ago I got my hair dyed black with a few Electric blue streaks. (that part had to be bleached and I simply had to add blue to my hair every 2 weeks to keep the colour going). I now would like something new for spring and was thinking to go really snow white blond. I will go to a salon, but wondering if its even possible, or do I need to do something first before I go see my hairdresser?

Leave head and shoulders in over night, that will strip you're hair, then either do 2 bleach sessions with 30vol or do two sessions with live colour xxl max blonde, this will be less damaging than the bleach
