dark brown to light brown

ok so about 9 months ago i dyed my hair so many times, so many different colors to try different things and when i finally bleached my hair to  make it a little bit lighter it just broke off, so i decided to do a light brown but it kept fading back to blonde so then i put a medium brown and still the same thing so then i put a burgundy and i liked it but it faded away fast so then i finally just did it dark brown to match my roots and my natural hair color.... that was about 2 1/2 months ago...... i did many deep conditioning, treatments, and hot oils........my hair is finally shiny and wayyyyyy healthier with very little damage but i cant stand the way i look with dark hair  and i want to lighten up to at least a light brown....i bought  a box of haircolor by loreal paris superior preference meant for dark hair in a ultra light ash brown but i tried a strand and it came out to a reddish brown what do i doooooooooo???
