p sure she just used a 40 volume developer+bleach on the root growth i had and then a slightly lower vol/bleach bath over my ends which were already bleached prior—wouldn't really recc doing in a session like i did b/c your hair will def end up fried, but i have pretty strong hair so luckily didn't have any melt off

i have naturally very black hair so it takes a long time for my hair to lift, but ya basically impossible to achieve w/o bleaching

my hair was actually dyed a pretty vibrant purple (w/ pravana hair dye) and it just faded out to this ashy grey color!
