Dark Brown

What is the easiest way to dye my hair light brown / dark blonde after I dyed it black a month ago?
I dyed my hair hair dark brown / black (not a deep black, but a dark brown-black of course.) I want to be a very light brown / dirty blond. Do I have pulling my hair completely, or I can somehow ease so I can dye the lighter color? The color seems to have eased considerably and it seems that only a brown quite dark. Have some cash on the same background.
First use a bleach. Strip it of its color as much as possible otherwise it will be clear hair for ages! Clarify that as far as poss with a bleach and starts to whiten, but wait 48 hours between each otherwise you destroy your hair. After half contrast to the color you want to leave him alone for a few months, the hair will thank you. I have dark hair and am constantly changing its color. Watch out for split ends and be kind to her.
