I dyed my hair turquoise and pink cruella. The pink faded to white but the blue will not budge. I've bleach bathed my hair as much as I'd like to without damaging it in the past few months but there's still a blue tint (like granny rinse blue? Very pale) but now is like to do an ombré style as I'm trying to grow my hair out so I wanted to dye about 2 inches of my roots back to my natural colour which is a mousey blonde. But I'm worried the blue will make it go horrible (even though it's very pale) will it work? Or what can I do?
