before just recently i had never in my life dyed my hair. i decided i wanted to be a blonde. i had super dark brown hair, and i wanted to do something fun. i got a bleaching kit, bleached it, and then dyed it semipermanent blue grey. or i thought it was blue grey. the the color did not come out like i had wanted, so i haven’t put that color in since. my hair currently looks like this.

i’m getting it cut today, probably shoulder length. the blue green is super faded, so if i want to dye it back dark could i just do it over that? instead of bleaching my hair again?
