sooo in february i dyed my hair from blonde to black. it faded to medium brown but my roots grew out a lot and my natural color is very ashy light brown almost dirty blonde. i decided about a week ago to color over it a medium/dark brown to go over my roots . i guess the color was too light and now my roots are way noticeable than before and my roots are so light then my other hair is dark brown. how should i blend my roots in without going black again?? should i just dye it dark brown ?my hair is extremely strong and can handle a lot, but i will wait about a month before dying it again i just need suggestions .

***** this i how my hair looks at the moment******
