Hey! I wanna bleach my hair to a lighter blonde (a bit short of platinum, i’ve attached a pic!) and have been slowly getting there. The last time I bleached my actual hair and not my roots was probably around january, so I feel it’s time to re bleach. How can I lighten it without damaging it too much? Would I be able to use 20 Vol? or is it not light enough, Thank you!:))

(I’ve attached a picture of my hair below also! Ignore that it’s a bit messy lol)
