This is my go to bleach! I've bleached my hair myself many many times and I've found that a few packets of this bleach mixed with 30 volume works wonders. I usually use color oops, a color remover on my black hair (dyed) to get it to a dark brown/orange, then this bleach takes it straight to blonde. I do usually bleach it a second time with a weaker bleach and developer to get any spots I missed and also lighten it a tad more, then I just use a blue/purple toner and purple shampoo to get perfect and beautiful platinum hair! My hair is always in good condition afterwards as well.
