I had dark brown hair, i dyed it g9olden brown, but its in patches of colour now.what shud i do?

Im chinese, with natural black hair. But i have had dark brown hair dyed from last year and black low lights. I decided to dye it light brown. So i used Loreal paris lighten golden brown. I have black roots like 3cm long. My cousin helped me dye. But problem is, colour was nice, but its really light brown at roots, thn its dark after roots, but if u tie hair up, thn its all the same colour. We realize when hair let down, only roots seem to be light brown. n the bottom part of hair brown. But not the middle hair? howcome? what shud i do now?

Go to a really good hair dresser and ask them to dye it out (((fix it)))
