I've dyed my hair recently to a turquoise blue, and I seem to be having some trouble with parts of my hair actually taking to the colour. I don't mean like the bottom or the roots, I'm talking half way down my head a random patch will be green right Inbetween the bright blue, or better yet a random square of bleach colour still that hasn't took to colour at all! Why is my hair not taking to the colours no matter how many times I've touched it up? And is there anyway I can fix this?

or:It sounds like certain parts of your hair aren't getting dyed there's not enough dye on those strands of hair I would color your hair in strands this might help to get a brush and do sections of your hair this will help those sections take the color that's what I had to do.
